If there was gravity inside a black hole then matter would accelerate faster than light. Their solution to this is to say nothing can fall faster than light. If this is the case then they can't say there is anymore gravity in a black hole.

There is a problem with black hole theory. They say time ends at the event horizon but somehow restarts and ends again at the singularity.They can't match the metric to what's really happening. It's divided in two. The metric doesn't match space-time.

There have been some unsucceful attempts to remove the end of time in the metric by Kruskal. I say time doesn't end at all and there is a limit to gravity. People will argue that what I am saying is wrong that black holes don't say that matter reaches light speed. They don't understand the physics. Time ending and falling at the speed of light go hand in hand in the theory of Einstein.

There really are no event horizons(ends to time.)

Hi Nick,
The way I see it (which could well be wrong) is that the mass in the hole curves the space so much that any light falling on the event horizon will shine (ultimately) on the thing in the middle (which may be a singularity). The curved space doesn't care one way or the other about light going through it or where it goes next so the curve is continuous through the event horizon. Roughly, I think this means gravity escapes from the singularity without worrying about the velocity of light.

A black-hole drops off into infinity. Light, therefore, would be travelling an infinite path...its not that it cannot escape.

Hi MMC,
Need to get my head round this - you suggest a black hole is bigger inside than out? As it tends to a singularity the singularity gets 'further away' ?

The infinities in black holes are the problem. Stephen Hawking pointed this out but he didn't actually pose a solution. Gravity is limited.

The first physicists that solved the equations for black holes thought they literally saw matter dropping out of the universe. We would see galaxies unraveling from their "black hole" centers if that were true.

There is no infinite path. In fact black holes are just the opposite.They are a complete end to space and time. There's no matter if there is no space-time.

This is from relativity:

A BH is a curvature of space, rather like a cliff face, that drops off into infinity, essentially a "hole". Beyond 4D space (Makowski), its internal structure is subject to speculation. We understand from relativity that the process is possible and there is some direct evidence of their existence. Optical blackholes are used in labs.

This would suggest that dilation is the key factor in the process.

Exactly, it arises from positive gain on dilation. In fact, a blackhole would continue to expand internally.

Sometimes I get the image of "blowing a bubble" and letting it float off...

It could be argued that a Black Hole is the formation of an independent universe...

Which would provide the "illusion" of an expanding universe from the interior, no less...

[COLOR=red]At the event horizon the reverse of inflation would occur and this is where the Einstein Tensor fails completely. I see space time being consumed gravitationally by matter aggregations. I think that Einstein should have worked on his field equations instead of the cosmological constant. There would be a warping and consumption of space time. [COLOR=red]
