Does a Black Hole Represent a State of Absolute Rest in the Universe?

In summary, the event horizon of a black hole is a place where time appears to stop and light becomes infinitely redshifted. However, for a falling observer, the experience is different and nothing significant happens at the event horizon. The center of a black hole is a place of absolute rest, and it is possible for it to move through the cosmos from its place of birth. The center of a black hole also serves as the "Either," where objects and light have a relative speed with respect to a place of absolute rest. The escape velocity formula with v=c can be used to calculate the Schwarzschild radius, and the gravitational redshift for light moving away from the horizon approaches infinity. However, for a free falling observer, the

Hello...

If time stops at the event horizon of a black hole..which means there is no motion happening or can be observed..does that not mean that the centre of a black hole is a place of absolute rest?

Could such a place of ab/rest 'move' thru the cosmos (basically a black hole which is a dead star) from its place of birth?

I would think that the centre of black holes would fill the role of the 'Either'...where both objects and light would have a relative speed with respect to a place of ab/rest?

Why can a light wave not leave the region of a black hole?

Thank you for any and all responses..it will help me to pin down certain ideas I have.
Bye

Use the escape velocity formula with v=c to get the schwarzschild radius.
If you calculate the http://en.wikipedia.org/wiki/Gravitational_redshift" for light moving normally away, you get z→∞ as r→rs+, so for r=rs it is physically dead

It is oversimplified popular explanation.
Yes, light from horizon gets infinitely redshifted.
But for the falling observer nothing happens when he crosses the event horizon.
For the free falling observer metrics is normal (locally) all the way to singularity

What is absolute rest?

Absolute rest, also known as absolute zero, is the theoretical state at which an object has no kinetic energy and all molecular motion ceases. It is considered the lowest possible temperature and cannot be reached in reality.

What are black holes?

Black holes are regions in space where the gravitational pull is so strong that nothing, including light, can escape. They are formed from the collapse of massive stars and can vary in size from a few kilometers to billions of times the mass of our sun.

How do black holes form?

Black holes are formed when a massive star runs out of nuclear fuel and can no longer sustain its own weight. The star then collapses under its own gravity, creating a singularity, which is a point of infinite density and zero volume, surrounded by an event horizon.

What happens at the event horizon of a black hole?

The event horizon is the point of no return for anything that enters a black hole. Once an object crosses the event horizon, it is pulled towards the singularity and cannot escape. The event horizon is also where the gravitational pull is strongest, and time and space are distorted.

Can anything escape from a black hole?

According to current scientific understanding, nothing can escape from a black hole. However, some theories suggest that tiny particles, known as Hawking radiation, can escape from a black hole, but this has not been observed or proven yet.
