Some of us believe a black hole spinning at light speed should have sufficient centrifugal force to create a donut out of a black hole. Passing though a black hole is a renowned for short cuts across the other side of the universe millions of light years in a few minutes to most pof us known as a wormhole Certainly much faster than light.
In popular many worlds theory culture as portals to parallel universes. It is suggested some form of exotic matter may do the trick. But at the end of the day the infinite gravitational pull is neutralized by the spinning finite speed of light speed.
Images show black holes as black discs silhouetted in the black drop of stars. What we the images show the outer edge where light disappears called the event horizon. It is believed there is a black hole in the center of our galaxy. Video clips show a tiny event horizon right in the center.
Gravity is renowned for compressing the mass of matter into a sphere. Video clips seem to support the view black holes are spherical with a center believed to be a point of infinite density and zero volume called the singularity.
The special shape of a black hole is the event horizon in collapsed inward pull force of the singularity. The unit is Newton's.
What would a black hole look like? Think of a glass sphere the size of a basket ball with a tiny near invisible steel ball trapped right in the center. The glass represents the inward pull of the event horizon. The outside edge the point where light disappears. If the glass ball spins it would be spinning like a planet the steel ball spinning on the spot inside while the outer edge travels a distance.
If the Planck constant is anything to go by the singularity is finite.
A Planck constant is 1 divided by 6262 followed by 39 zeros a total of a 34 decimal number of a meter. That is smaller than a atom. Known as a Planck length. It is also known of a second (Planck time), a kilogram of mass (Planck mass) a Planck volume, a Joule (Planck energy) and temperature. It is a fixed minimum and maximum. It just doesn't get any smaller or bigger than that. The scientific notation is 6.262 times 10 to the minus 34. If this is anything to go by a Planck mass is a gravitational force of 6.262 times 10 to the 34 kilograms of gravitational force center to the edge (radius) of the singularity.
If the line of the equator of any sphere is opened out to a straight line reveals the fact that all straight lines are the equators (the circumference) of all spheres. Proof of this all straight lines when rolled into a circle will equal the circumference. We can measure the length of all straight lines equal to rolled into a circle the circumference of all spheres and the singularity should be no exception.
If a black hole was spinning on a light speed scale the boundary of the event horizon would be spinning at the speed the speed of light. The singularity in the center would be spinning on the spot deep in the center. Spinning on the spot there would be very little to no centrifugal force. However the boundary of the event horizon would have distance to travel round where the force will be concentrated. Whether the finite speed of light would be able to effect the infinite gravitational pull is a matter of debate.
We often learn much when Black holes are static voids. If we look out of a black hole to the universe we may see a blinding heavenly white light of incoming light from the universe. From the universes point of a total black void. If a Planck constant is anything to go by, by looking outwards to the universe time would be 6.262 times 10 the 34 times as fast while looking into the black void time is equally 6.262 as slow.
From earth an astronaut would look suspended in the event horizon every 6.262 times 10 to the 34 years. But to the astronaut point of view 6.234 times 10 to the 34 years pass in every second.
