Thread: Einstein, time reversals and black holes

I have a question that is indirectly linked to what happens inside of a black hole. I know the standard answer is that it is undefined, however I would like to take a different approach.

Lets take a 1 d diagram with a stong gravitational source ( OK a Black hole ) that looks like this:

--------X----------------EH----------Singularity

Where X is an infaller
EH is the EH
and Singularity is the Singularity

Now for a distant observer as X approaches the EH the infallers time will appear to stop. At the EH time appears to stop.

The natural progression is that the flow of time would be negative after the EH or would it just be imaginary? or just undefined.

If it is negative ... what would that mean?
for dx/-dt = -dx/dt ... which should mean that relative to the distant observer ( although he could never observe it ) X's velocity is in the direction of the EH and not the singularity right? Locally the infaller is rushing to the singularity at full speed.

Now one may say that if time is stopped at the EH then from the prospective of the distant observer nothing can fall past the EH ... however with that being said there are ways of getting past hte EH ...

1) at the collapse of a star at the point where the mass density is above the critical density to form a black hole most of the mass is already inside of the EH ....

2) as a black hole attracts more mass the potential gravity of the new mass will make the EH expand past the mass at the EH ... Although time is stopped at the EH the EH is expanding outwards.

i always wondered what would a distant observer see if they were to watch a person fall into a black hole? if time stops for the person entering the bh and light cant escape a bh, what would someone from a space ship see as their friend enters the event horizon? would his friend instantaneously disappear?

Well lets say their friend had a blinking flashlight ( at set intervals lets say 1 blink every second ) and were sending signals back to them ... as their friend approached the EH the distant observer would see the signals becoming slower and slower and more red shifted for each blink. The period of time between each blink would get very large ( I dont think it approaches infinity because the EH actually will expand outwards as the friend got near it ) until the last photon would be sent ... then nothing ... ( except hawking radiation at some point ).

Hi Tom,

One of the problem of current physics is the notion that time, which Quantum-Geometry Dynamics shows is a concept and not a property of reality, is treated as if it was a property of reality.

I have shown in Quantum-Geometry Dynamics that time does not slow down, it does not expand, it just 'disappears' at the fundamental level of reality (see Part 1 of the Introduction to Quantum-Geometry Dynamics which can be downloaded here in PDF format.

As you will see, QGD shows that Einstein's inference of the relativity of time to explain the consistency of the speed of light measured by the Michelson-Morley experiments, not only wasn't the only possible explanation, it was an inference that was not mathematically sound. QGD shows that there is no need for the concept of time to describe interactions at the fundamental level of reality.

This resolves all the paradoxes that result from General Relativity. It also resolves the problem known as the Vacuum Catastrophe, which discrepancy has been termed "the worst theoretical prediction in the history of physics!" The Vacuum Catastrophe is probably the most spectacular demonstration of the inconsistency and failure of the Standard Model.
