Let us know what you think

Mr. ScientistWhat are the four boundaries?Thank you my friend!Webo
What is beyond the event horizon of a blackhole?Nothing. There is no beyond it. At the event horizon of a black hole, the time dilation is infinite for observers in the universe at large. That means the "coordinate speed of light" is zero. So a photon heading towards the black hole simply stops.
People talk about the "proper time" of an infalling observer, but imagine this is being measured using a light clock. That photon has stopped, so that light clock is stopped too. That proper time is being measured with a stopped clock. So it isn't proper at all.
Since we define our second and our metre using the motion of light, when light doesn't move you can't measure anything. So the internal dimensions of the black hole are undefined.
Actually, you have it exactly backwards. The light clock matches the proper time and the infalling observer sees the light clock operate normally.
