trying to make a video about a star going into a black hole

In fact its hands will asymptotically approach a certain time, which we might as well call 12:00. What we notice as the clock approaches the event horizon is that it slows down compared to our clock. We will stand a long way from the black hole and watch the clock fall in. By 'classical' I mean a black-hole solution to Einstein's equations, which we imagine not to emit Hawking radiation (for now). I will attempt to describe the situation as best I can, to the best of my knowledge.įirst, let's imagine a classical black hole. It is true that, from an outside perspective, nothing can ever pass the event horizon. If observers see objects slowly fade and slowly disappear as they approach the event horizon would that mean that over time the event horizon would be 'lumpy' with objects invisible, but not passed through? We should be able to detect the 'lumpiness' should we not through? Again, please keep thinking from an observers point of view. OK - just an edit based on responses so far. Why would it slowly fade and if it would how long would this fading take? If it is going to red shift at some point would the red shifting not slow down to a standstill? This question has been bugging me for years! I am getting ready for the response of the object would slowly fade. If I was able to train the telescope onto the black hole for millions of years would I still see the rock at the edge of the event horizon?

I have it focused on the black hole and watch as a large rock approaches the event horizon.Īm I correct in saying that from my far-away-position the rock would freeze outside the event horizon and would never pass it? If this is the case how can a black hole ever consume any material, let alone grow to millions of solar masses. In my thought experiment I am in a spaceship with a powerful telescope that can detect light at a wide range of wavelengths. If this is the case how can anything ever fall into a black hole.

This is also the point I understand that according to Einstein time dilation will be infinite for a far-away-observer. The event horizon of a black hole is where gravity is such that not even light can escape.
