Has anyone done this calculation? It seems to me that if light and time disappear at the event horizon, it's a gravitation limit as well.
They don't, some popularised descriptions notwithstanding.Shaw said:It seems to me that if light and time disappear at the event horizon
You seem to be confusing fields with disturbances of fields (waves):Shaw said:It seems to me that if light and time disappear at the event horizon, it's a gravitation limit as well.
Thank you. That's reasonable. Do we have any information about what happens to time inside the black hole since gravitation and time are bound together. At the event horizon, time dilation can't increase since it shares the light limit velocity. If gravitation is calculated from the centre, and the max. velocity in gravitational space is c, we seem to have a void of gravitation and time from the centre to the event horizon.Dale said:No. In any sense that gravitation starts, it starts at the white hole's singularity. Or in a more realistic spacetime it starts with the material of the original star before it collapses or even forms in the first place
"time dilation" is never something that happens at a location.Shaw said:At the event horizon, time dilation can't increase
You've certainly picked up some very strange misconceptions about black holes!Shaw said:Thank you. That's reasonable.

Well, we don't have any experimental information, but we do have plenty of theoretical information. Clocks continue to function normally until they get close enough to the singularity that the tidal forces break it. Depending on the size of the black hole and the delicateness of the clock this can happen inside or outside the horizon. The only thing is that clocks inside the black hole cannot communicate outside, but they can continue to function.Shaw said:Do we have any information about what happens to time inside the black hole since gravitation and time are bound together.
The event horizon of a black hole is the point of no return, where the gravitational pull is so strong that not even light can escape. It marks the boundary of the black hole where the escape velocity exceeds the speed of light.
Yes, gravitation does start at the black hole event horizon. The event horizon is where the black hole's strong gravitational pull begins to take effect and objects are pulled towards the singularity at the center of the black hole.
No, nothing can escape from the black hole event horizon. The gravitational pull is so strong that even light cannot escape, making it impossible for any object or information to escape from the event horizon.
The event horizon of a black hole has a significant impact on time and space. As an object approaches the event horizon, time slows down and space becomes distorted due to the strong gravitational pull. This phenomenon is known as gravitational time dilation.
Yes, the event horizon of a black hole is a physical barrier. Once an object crosses the event horizon, it is impossible for it to escape the black hole's gravitational pull. The event horizon acts as a one-way membrane, allowing objects to enter but not leave the black hole.
