If you had the knowledge to build a portal that links to parallel universes or the opportunity to slide a whom hole to other worlds what would you do. This is what happened to the inviter of such a portal Quinn Mallory  Inventions and discoveries are discovered by accident tweaking with inventions all the time. It happened to a university student Quinn Mallory in a science fiction TV series called the sliders experimenting with antigravity in his basement in an attempt to revolutionize heavy lifting. Instead of antigravity the experiment ended up creating the holly grail of cosmology the Einstein-Rosen-bridge to us a wormhole. They are cosmic tunnels bridging one part of the universe to the other. In Mallory's case a portal exiting into the dimension of parallel universes.
The pilot opens Quinn waking up one morning reflecting on an antigravity experiment he was running the night before. Wondering into the kitchen his mother was up pottering with breakfast.
A conversation about his father revealed he was very close that had died when Quinn was only seven missing his father very much. After motherly fussing Quinn wondered down stares to the basement that looked more like a science lab the a typical student's study. He reached for a video cassette pushing it into the machine sitting in an armchair.
The video revelled a diary of his antigravity experiment working. He watched his own descriptive chronology describing the roaring midd air whirlpool with a camcorder in a hurricane force winds
Pondering on his antigravity he reached out and took a framed photo pose of himself and both parents reflecting how much he missed his father.
Realizing he was going to be late for his lecture he replaced the photo and hurriedly shut down and hrried  stares, hurriedly snatching a bite to eat from the breakfast table. Down the front walk he went opening the front gate that squeaked closing it. He jumped into his car and set off to campus.
Running though the  campus grounds he passed a homeless guy raving on about the end of the world coming pointing a accusing finger at him. Quinn was in to much of a hurry to stop telling him was as he on running past the familiar statue of President Lincoln.
In a lecture room a professor at a scientific scribbled math's formulae blackboard one of the stares of the New Zealand movie Lord of the Rings John Ryes-Davies, playing the part of, Maximilian Arturo, showing his annoyance Quinn was late for class "again". Quinn humbly apologized seating in his chair.
When he explained he was onto something interesting his co-students were dubious much to the annoyance of the professor constantly trying to keep his students focused on his lecture.
After scolding Quinn and trying to keep his student in check in van for ten minutes the school bell ring Arturo dismissing the class. As the class broke up Quinn headed off to his part time Job at a PC store
There he discussed his find with his disbelieving best friend Wade Wells and co-workers. When his time was up he made tracks back home to his basement.
There he settled down to more reflecting, studying and pondering staring at his scientific scribed blackboard full of scientific formulae trying to see a Patten that could describe his experiment.
He cranked up his experiment once more. Chirorrrrrrrrrrrrrrrrr it went spreading from a small point opening several meters wide looking like some midd air water whirlpool roaring and sucking at the basement atmosphere like a giant air conditioner. He stood for a moment before walking round behind it.
He passed behind doing a complete circle checking where the tunnel was disappearing to. What was his antigravity experiment creating ? The roaring midd air vortex collapsed in on itself with a Shawormph! leaving a normal and quiet basement environment behind. His experiment had somehow managed to reproduce something He started it again. Chirorrrrrrrrrrrrrrrr it went expanding wide open pulling in on the air.
Quinn did some more running complementary though his video view finder reporting what was happening. It collapsed inward on itself closed with a shawrrrrrrmph.
After a while he began realizing what this midd air vertex was. It was a quite a surprise. Had Quinn's antigravity experiment had somehow created a singularity in his basement here on earth?
Mallory excitedly cranked up his machine again. With a chirorrrrrrrrrrrrrrrrrrrrrrrrrrr! roared the vortex like a hurricane. Studying it he observed as much as he could before the vertex collapsed with shawormph! on itself again.
He considered testing the stable entrance placing objects through it. Placing a beach ball at the foot of the mouth it snatched it disappearing into the center closing on it with shawormph!
After a few minutes waiting while he studied scientific filed equation blackboard he started the machine again. With a chiorrrrrrrrr on opening. The ball shot back across his basement. Retrieving it he reflected what he was holding.
"Where had theses objects been"?
Some investigative thinking staring at the scientific formulae scribbled blackboard again looking for a pattern written in the mathematics
What was holding open the vortex? Antigravity maybe? Power!! But why not for long?"
He soon realized their was a drain while holding the roaring hole open quickly running down until it could not hold it open any longer. Anybody familiar with on the road with laptop batteries know the feeling as they automatically shut themselves down when the batteries are to flat. Observing the behaviour of the formula he realized there was a some sort of timing pattern.
Quinn soon realized his machine was automatically recharging back enough power he could restart the vortex again. He considered sending his believed cat but though again reluctant in case his feline panicked on the other side never seeing her again. Eventually he considered trying it himself. Soon his confidence in taking the plunge was growing.
With much reflection and self arguments for the pros and cons of jumping into the wormhole, to satisfy his curiosity he set to work on a electronic hand held trimming device to count down when the time was right to open the vertex to get back home. With the timer in his hand he pressed the timer bottom. With a chiorrrrrrrrrrrrrrrrrr! the vertex opened expanding to full size in front of him.
Finally he took the plunge. He dived into the vortex disappearing into the centre or more like he was snatched in. It collapsed behind him with a shawromph! The basement quite and deserted, then the chirorrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrrr! sound expanding open a vertex from a point of light to full size. Out shot Quinn yelling at the top of his lungs somersaulting landing on his back on the floor.
Picking himself up he examined his surroundings the vertex still roaring away open. Then it collapsed in on itself with a shawromoph He studied where he was for some time taking in the very familiar surroundings. Looking back at the point where the vertex opened although he experienced sliding something incredibly unique apparently he never left this world.
Considering linking to another world was a failure he tidied up before setting off back to university. Outside he looked back to his front porch were everything about his house exactly the same as he remembers it, even his own car parked on the curb. As he opened the gate he paused with a curious frown. Strange, there wasn't the familiar squeak when he opened it. Oh well, dismissing their hired gardener may have fixed it he closed the gat jumping into his car.
Approaching an intersection deep thought he ran a green light.
To his suppressed motorists reacted the way we would when some one runs a red light on us at a intersection. With screeching of tires cars nearly collided pulling up to sharp stops all over the intersection inches from each other.
Scratching to a stop himself avoiding an accident he looked out the window in amazement at the behaviour of the other motorists road raging abuse at him and driving round tooting their horns as they drive on though red lights and waited at greens .
It was then he realized he must have landed on another world after all. It was a mirror image of his own. With excitement he realized he'd just slid an singularity ( the gravitational field right in the centre of black holes ) or the holly grail what is known as the Einstein/Roseburg bridge. After getting over the shock he excitedly u-turned careful to stop at green lights and run red lights back to his parallel world home.
Waiting at a green light he happened to spot a billboard advertising a current Elvis Presley gig. There was Elvis as large as life. He hug the wheel amused wonder peering though the cars windscreen. His radio was blaring a talkback show host interviewing John Kennedy.
Shaking his head in wonder he drive on. Quinn pulled up to his parallel world home. Opening the gate he stopped short at the sight of his mother arm in arm escort style with the hired Gardner.
It appeared as his mum was married to him for some time. During a confused conversation he heard a quiet beeping in his pants pocket.
What's that?
Realizing it was him he whipped out the timer seeing the sixth digit was counting down to zero 00.00.05, 00.00.04, 00.00.03, 00.00.02, 00.00.01 then all six 0's blinked a couple of times
With a chirorrrrrrrrrrrrrrrrrrrrrrrrrr! the vertex opened behind him snatching him disappearing backwards into it closing with a Shawormoph!
The next thing he lands flat on his back in his basement the wormhole collapsing closing with Shawromph! much to the frightened astonishment of his cat.
It took him a minute to gather his bearings before he realized where he was back home. With great joy he bounded up stares to check his mother wasn't married to the gardener kissing her on the forehead racing outside.
In euphoria he hug the grader who was suppressed, and oh joy the gate squeaked when he opened it. He Jumped back into his car and raced off to campus to tell everybody what happened to him. After all not everybody gets to slide a Einstein/Rosenberg's bridge to another world.
Arriving late again he eagerly interrupted the professor in the middle of a lecture. The professor sorely told him he had a nerve to show back at class. Quinn stepped back a bit not understanding. Still, he was eager to talk to him about his discovery and eagerly persisted. Now the professor felt Quinn was mocking him and his theories.
Quinn desperately tries to explain he wasn't. Quinn finally got though enough of the professors resistance to come to his house and see for himself.
Not fully understanding what was going on with the professor, he heads off to his part time job. Arriving for work, Wade confronts him at what he's doing back there.
A surprised Quinn replies he works there. She informs him the manager fired him a little while ago when he told him off. Quinn claims he didn't remember. Then Wade asks if he doesn't remember the kiss either?
Quinn was astonished wondering why he do that to his best buddy not believing the accusations thrown at him. First he successfully created a Einstein/Rosenberg bridge then slid it to another world and back and then this.... all in one day? Wade walks off huffily on him leaving him flabbergasted.
Quinn, still not understanding what's going on and since he'd been fired from his job he doesn't remember decides to head home.
Quinn returns to his dark scientific lab. He switches on the light reflecting on the machine consoling himself nursing his cat surrounded by electrical coil windings. He wonders over to the formula scribbled blackboard and studies it for a minute. Then his face changed into a curious frown.
He discovers the formula he wrote down unable to finish altered. He doesn't understand it. At this point Quinn hears a slight stir and turns to look straight into the eyes of himself. Getting over the initial shock, Quinn's twin seemed to be a bit of a brag revealing he was from a parallel world showing off he too experimenting with an antigravity machine turned into this bridge.
Quinn's double revealed he'd visited his university and admitting he was the caused of the stir with his professor. Quinn learnt he was the one also responsible for kissing his wade as Quinn's double was married to Wade's double. To Quinn's relief it reveled why he was in so much trouble.
Both spent ten minutes discussing and comparing their inventions. Quinn's double showed off pointing out were this Quinn went wrong with his formulae. Then it was time for Quinn's double to leave. Quinn's double opened the vertex. Chirorrrrrrrrrrrrrrrrrrrrrrr it went, spreading from a small point to wide open. The noise was defining like the middle of a hurricane. Quinn's double tried to speak over the roar. But all Quinn could yell back pointing to one ear.
"I CANT' HEAR YOU!!".
At that Quinn's double was snatched away disappearing into the vertex and was gone.
Meanwhile Wade and the professor on Quinn's door step were concerned about his strange behaviour and obsession with his invention.
The professor rang the door bell. The door opened to revile Quinn's mum. The professor explained they were her to see Quinn. Invited inside there was much introduction pleasantries the professor and Wade intrigued meeting Quinn's mother.
Meanwhile a washed out 1960's black rhythm blues singer an X-member of a pop group getting ready for an expected solo come back. His manger hovering in the background was advising him of the potential disappointments if was a failure and the consequences of going solo from his band.
Rembrandt Brown liked to think he was renowned for one of his particular favourite sad songs he was obsessed with he could bring tears to everybody's eyes when singing it calling himself Gyring man brown.
Meanwhile Quinn was engrossed an electronic assembly of his timer while Wade and the professor were coming down the basement stairwell still concerned about Quinn's odd behaviour.
When Quinn looked up from his job he was pleased to see them excitedly welcoming them promising he will be with them in a second turning back to the finishing touches of his timer.
When the professor saw Quinn's formulae scribed blackboard complete with the solution to the bridge he was beside himself with admiration dismay.
Quinn put on the finishing touches and excitedly showed the processor what he was holding was the key to getting back home when visiting the other side of the bridge.
Rembrandt comes out of his San Francisco apartment building to his big bright red Cadillac getting in and drive off down a San Francisco street.
In Quinn's Basement Quinn was eagerly ready to open the vertex much to the professors reluctance pausing a bit while the professor wasn't sure about it, Quinn pointed and pressed the timer button. Chirorrrrrrrrrrrrrrrr it went spreading open.
Wade and the professor faces was  shocked with surprise at a roaring, quivering vortex hole in mid air in front of them that seemed to be sucking the hole of the earth's atmosphere into it like some giant air conditioner.
Back to Rembrandt he comes out of his San Francisco apartment jumping into his big bright red Cadillac drove off down a San Francisco street.
In Quinn's Basement Quinn was eagerly ready to open the vertex much to the professors reluctance pausing a bit the professor wasn't sure about
Quinn pointed and pressed the timer button. Chirorrrrrrrrrrrrrrrr it went spreading open.
After they got over the initial shock at what they were witnessing before their very eyes Quinn asked what would they do with this opportunity to see what's on the other side.
Wade beside herself exclaimed "You mean we can just like, slide though this and BOOM! we're on another planet"!!
"NO"! exclaimed Mallory. "Same planet! Different dimension"
What would you do if you had the opportunity to slide a wormhole to explore a different dimension? The professor was a very reluctant and unsure holding back. Wade was beside herself with excitement.
As giddy as a little school girl over puppy love she talk them into jumping much to the professors arguments against it. The pair argued for and against to the backdrop of the roaring vortex.
It took quite a bit a bit of persuasion to the reluctant Quinn and the professor, but she finally persuaded Quinn to let them try.
Rembrandt drive his a bright a red Pontiac convertible happily rhythmically beating to his favourite crying man Brown song at the wheel.
"Oh yeaaaar baby. It's gona be good"!
The trio prepared themselves ready ride the vertex. Quinn had originally set the vertex to carry only one person. He had adjusted the power for three more people. Then at a one, two, three, count they let the vortex snatch them into it and they were gone. The vortex collapsed with a Shawormph!! and all were gone.
All that was left was the scientific formulae scribbled blackboard in a deserted and silent basement. Outside the side of Quinn's house, the roaring vertex expanded open to full wideness outside it's designated area. Rembrandt Brown at the wheel of his car stiffened with a curious frown at a spectre like circle at an intersection in front of him.
In shocked surprise and fear he saw as if the whirlpool spotted pray changed directing turning straight towards him. Over the front of the car bonnet he saw the roaring whirlpool mouth like a horror movie scene glide straight toward him.
Yelling at the top of his lungs, frozen with fear at the wheel the car drove straight into the roaring mouth closing behind him with a Shawormmmmmph!! leaving a normal and deserted street behind.
Inside the vortex Quinn, the professor and wade sailed along in a sideways plane like falling from a high sky scraper at high velocity. The bright red convertible sailed pasted past with the screaming crying-man Brown at the wheel narrowly missing them by inches. The bridge was taking them on a wild twisting and snaking Rolla coaster ride.
A basement looking like something out of the a frozen scene from the day after tomorrow movie set. Chirorrrrrrrrrrrrrrrrr a vertex expanded opening spreading wide from a tiny spot in midd air. Out flew Rembrandt's red Cadillac convertible Brown yelling at the top of his lungs skipping across an ice frozen yard banging to an abrupt halt into a ice wall.
Finally the professor and wade next. A moment later Quinn shot out just as the vertex collapsed inwards closing behind them with a Shaworrrrrrrrrrmph. Rembrandts car was quite for a moment. Then the cardiac door opened and out stepped brown into freezing snow.
The professor, Quinn and wade, recovering their wits, could see they were not in a familiar environment. Wade had got her wish. The trio began exploring the parallel reality surroundings. Some candles were found. lighting them they were little islands of flickering light in the near darkness. For some time an interesting discussion about what could have happed and to all the occupants for about ten minutes or so. Wade found a crumpled photograph handing it to Quinn.
He took the photo showing the same shot he had at home only with a strange girl and his pet dog he recognized. He explained the pet had died a while ago and didn't know anything about the girl in the picture. Quinn and the professor discussed some scenarios of what could have happened to his familiarly considering this frozen world.
Shivering Rembrandt blowing mist of warm air into cupped hands spotted the tree island of flicking candle light in the porch doorway of an ice covered house just ahead of him.
When the professor, Wade and Quinn stepped out onto the porch they were shocked at the spooky panoramic view of San Francisco harbour complete with the Golden Gate bridge locked in ice with spooky dark tornado storm clouds hanging over the whole city.
Getting over the shock their attention was brought to the dazed traveller gathering his wits out side the house beside his car in an the snow yelling confused obscenities at the trio.
They joined Rembrandt who was demanding answers to what the hell was going. To keep warm it was suggested the canvas roof to be razed in place. As soon as canvas roof settled on the rim of the windscreen they all got into the car completing the four travelers.
Brown was by now raving mad demanding to know who the hell these strangers where and what ever's happing to be returned home immediately. A discussion amid snapping tempers specially from the processor, trying to analyses the situation ensued.
Soon they felt and heard something in the air by the change in air pressure. To their horror they discovered the place was full of tornados, the one they felt coming in screaming a whirlwind precariously close to the little group huddled in the convertible. The roof was lowered back everybody scrambling to stand on the back seat the storm snapping at them in an effert the vertex could snatch them away to safety.
Quinn fumbled at the timer pointing to the sky initialized it. Chirorrrrrrrrrrrrrrr went the vertex opening wide above them.
One by one they got into position letting the gravity snatch them up into the roaring hole in the air. Again like falling from a high sky scraper velocity.
The deep depth of a blue sky above. Chirrrrrrrrrrrrrrrrrr went the vortex spreading open.
Out fell the professor landing heavily on his side rolling face up when Wade landed on him face down steering into each other eyes. Then it was Rembrandts turn. landing on his backside nearby. Picking themselves up there was a long pause as the vertex continued to roar still wide open above them. Where’s Quinn?
There was a frightening long wait expecting the vertex to close any second without depositing him. The wait was becoming excruciating. Still the vertex remand open
Just when Wade was in tears at the shock of loosing Quinn to god knows what, not seeing him again. Then out fell Quinn, the vertex collapsing with a Shirorrrrrrrrrrrrph even before he hit ground landing hard face down on the grass All members were glad he was safe, specially wade.
Quinn and wade hugged each other gratefully Rembrandt smiling like an ape in the background. Assuming they were all back home Rembrandt was still angry telling them off. He reminded Quinn he'd lost his car and not going to hang around and miss his singing appointment. Spotting a taxi coming down the street he hailed down the cab promising to get back to Quinn about his favourite convertible.
Meanwhile Wade said she was off to find a phone box to ring home to tell them about the adventure she had. She had no problems with her family not believing her as Rembrandt Brown the crying man, Quinn and the professor would collaborate her story. So off she went.
Quinn and the professor set off discussing their next move when suddenly the professor pulled Quinn up short pointing up to the park statue of the historic Russian figure of Joseph Lennon of the Russian revolution fame during our world war one. It was then they realized the truth of were they were.
Meanwhile Wade inserted a coin in the phone booth trying to contact her family number witch didn't exit. Strange. When she came out she saw the well known Russian hammer and cycle symbol above the door and the words in bold red capital letters in English
PEOPLE'S TELEPHONE AND TELEGRAPH
Meanwhile there a couple of shadowy figures looking typically FBI watching Wade with close attention for a minuite.
Meanwhile Rembrandt was telling the cab driver who he was and going too, while spotting the strange cab drivers identification passport which seemed a bit odd for a taxi cab driver. Still. The cab driver said he'd never heard of him. Then Rembrandt frowned in indignation and puzzlement at the strange behaviour of the cab driver specially when he suddenly pulled up abruptly and saluted stiffly in Russian in imposing Russian military uniform..
Rembrandt looked curiously to the direction out the cab window to a political rally of the suited homeless guy of his world shouting and ranting politically, flanked either side by two Russian solders. Although Rembrandt didn't recognize him Quinn, and the professor passing by sure did. Still indignant remembering had a few words to say puling out a dollar note from his trouser pocket flicking it handing it to the driver. The driver took the note examining it like someone spotting a countrified note when they see one.
The driver hailed over a tough looking woman officer who's face peered in the window. The driver showed the note. The officer taking one look at it, Rembrandt found himself encircled in the back seat of a Taxi cab by a armed gang of Russian solders pointing guns menacingly at him though all windows.
Nearby Quinn the professor noticed the missing presence of Wade. Then suddenly they found themselves surrounded by what looked like a gang of menacing FBI agents.
Quinn and the professor chained hanging from a wall by their wrists were unshackled and marched off under escort. They found wade unharmed and learnt they were captured by an underground resistant moment. They also learnt Wade's double was a martyr hereon leader killed in action by the Russian authorities in this world. It turned out in this world America was a Russian Dominion.
Quinn, felt it strange one of his part time co-worker there even though he knew he was only his double as one of the resistance fighters who had a crush on wades double monitoring a live court room TV program in progress. It turned out Wades double had a lover leader of the resistance who missed her dearly.
Wade had convinced him where she and her group had come from. Quinn insisted Rembrandt had to be found reunited with the group.
Casually watching the court room drama on television, Wade recognized the cab driver thinking nothing of it. Wades eyes pop out of her head in shock at who she saw in court. She cried out to Quinn and the professor to come and have a look at this. Quinn and the professor came over just in time to see Rembrandt stepping into the defendant stand.
Rembrandt was made to swear the oath of truth and the cab driver did the same. He was accused as criminal counterfeiter much to the shock of the Quinn wade and the professor. The group watch the proceedings unfold till the next case while outside the court room doors Rembrandt was intervened how he felt.
That was all it took for Quinn, backed by the professor and Wade they now had to rescue Rembrandt. A plan of action was hatched. The professor looked the type to be General, while the others were busy discizing  in various army officers and solders uniforms. They marched off to rescue Rembrandt from the caught room holding cell.
A tense moment the rescue group was challenged by a army unit where the professor bluffed his uniform authority to an officer which wasn't sure it was going to work until the intimated officer allowed them on.
Rembrandt was lead out of the cell pleading with a heartless officer when their was a attack. Then a gun fight erupted.
After it was over there was a drama moment Quinn thinking Wade had been killed. It was OK as wade appeared behind him. Turning round they immediately hug at each other.
With a sombre remembrance of their brave martyr was held while Quinn and the professor attended to the damaged timer. News of them now wanted reached the resistance. A renewed urgency to escape was called for.
Quinn and the professor picked up the pace fixing the timer. Once ready to go they needed to be at the right coordinates which was Lennon’s statue a k1/2km away.
The resistance leader offered to hold up the search team buying time. Soon our little group was on their way passing a homeless guy swigging at a bottle of cheep wine. With shock they recognized Quinn and Wades part time job boss sucking at a stubby cigarette. Getting over the shock they resumed their walk
They heard the sound of the posy far behind. Our group quickly broke into sprinted haste the pursuing squad gaining ground behind them. Reaching Lennon’s statue Quinn checked the timer finding it wasn’t quite timed out yet, only a matter of a few seconds left.
They Checked the pursuers behind them appearing only yards ahead. They weren’t going to make? Finally the timer could be initiated. Quinn hastily pressed the button pointing to a hedge.
Chirrrrrrrrrrrrrrrrr went the vertex spreading open. There was no time to wait. One by one they dived disappearing into the vertex.
Wade and the professor laid sprawled in roses, with Rembrandt on his backside close by. Quinn come out head first as a Shawormmmmmmph the vortex closing behind him. When everybody picked themselves up they had landed at the feet the President Lincoln statue. There was great rejoicing and laughing. Then they were ready to move on. Quinn stopped short the group. There sleeping under the Lincoln Statue was the homeless guy Quinn knew all to well.
"Nice to see you man" he said.
They saw a pair of headlights coming up the street. It was a taxi. They hailed it down. Getting in was the same taxi driver Rembrandt in the Russian American Domain world. In the corner of the back seat Rembrandt cringed panicky saying a few aggravated words at seeing who the taxi driver was. The driver wondered what was wrong with their friend to the rest of the Group. The professor looked at the diver as if to say that's a long story. Rembrandt check to see if the driver had heard of crying man brown.
"Year Sure! I know crying man brown!"
Rembrandt was happily pleased to hear that. Arriving at Quinn's address they got out, the professor paying off the driver the cab pulled away.
There was tension when Quinn was about to check to see if his front gate squeaked. To all there relief it did. Wade and Rembrandt hugged each other at the delight of Quinn and the professor behind. They went up the front porch stares Quinn opening the front door calling his mum announcing he was home.
When his mum came down the stares, he gave her the biggest cuddle he could please to see her. They went into the lounge where to reflect and disused the adventure they had riding Einstein/Rosenberg over drinks. Finally Quinn razed his glass of red wine in toast of his antigravity experiment. Just then there was the sound of the classing of the front door.
Everybody looked over to a man coming into the lounge. Quinn stood face solemn recognizing his father. His mother welcoming him in. Wade looked at Quinn with a Ohu-oh opps look on her face. Rembrandt and the professor's looks of disappointed realization.
Quinn in shock just closed his eyes as if to block out the site, letting the the glass of red win fall crashing to the floor.
There the pilot left it at that rounding of the family a TV screen displaying Rembrandt brown doing a live show on television with rolling credits.
The timer was not in control of the bridge until fully charged. When fully charged enough the timer would let them know with electronic beeping. When the number reach a long list of zeros the quad could open it. Just pointing and pressing a button sent opened the vortex.
There was a dead short power drain very time the portal was opened.  The self rechargeable DC power supply battery arrangement immediately discharged flat. This left the quad forced to hang around each world until the power supply was charged enough to open it again.
Quinn didn't realize until a few episode latter, what the warning of his double meant. If the timer was prematurely activated before fully charged it would corrupt the coordinates to get back home. This was what happened when trying to escape the approaching tornado Ice world.
Thus began the on going adventures of the sliders sliding from one world to the next hopping the next one would take them back home all throughout the series.
One episode the professor's double news media lecture referred to as an Einstein/Pulaski/Rosenberg bridge for the first time. Einstein and a couple of his collages Rosen and Pulaski  trying to prove quantum physics was incomplete ending up discovering Einstein's general theory of reality pointed to the theory of black holes predicting the bridge effect.
A few episodes later the series introduced to alternate world beings called Crowmags illustrating different life forms evolved from any number of the combinations including us and our entire history on earth of our ancestral brothers the Cro-Magnon men that once lived along side us humans.
Theory goes billions of alternate realties these Crowmags evolved along side humans on one earth that was at constant war with these humans for centuries. In the sliders program Crowmags where also sliders bent on enslaving humans in the different worlds they travelled to. If you saw the series one can only imagine what it would be like to travel to parallel human worlds for ourselves.
The curious romanced by the exciting possibility of creating a home grown wormhole in their bedroom or even the right conditions for time travel, have a wealth of text books on Einstein his theory of reality, wormholes and time travel theory's can turn to these library books.
They uncover vast amount of data about Einstein and his theory that can become vary familiar with. His theories are well worth looking at for the curious if Mallory's machine could be duplicated. The sliders TV show showed implications of doubles that exist in the same space and time as us living different life because of the infinite amount of decisions we make alternately deciding our doubles and us outcome.
The curious discover Quantum physics getting more and more intrigued become very familiar with what it is and how it works in relation to explaining how our doubles could exist in other parallel earth's.
The intrigued have so far been introduced to gateways to these double earths though the legendary wormholes though swatting up on black holes familiar with the books describing how Einstein's matter bending space believed to created by the massive gravitational pull of the centre supposed to great create infinitely deep sink wells in the very fabric of space.
According to the sliders TV show the intrigued wish's they to can visit parallel earth's sliding inside one of the deep wells landing in worlds expecting to find slight but differences in Geological features almost identical to their our own
