Where's exit for Black Holes in curved space?

If it's going in.....it must be coming out somewhere right?. Maybe the opposite side of an inside sphere?. Or Klines Bottle maybe?.....maybe I should stick to smashing atoms on the sidewalk with a hammer.

Pretty good question Larry, but I'm not 100% sure if there "IS" an "EXIT"...

Let's wait and see if our group experts respond to this one... interesting one indeed...



Clear skies!

As I understand it there is no general agreement as to what happens inside the black hole. Relativity would say everything just gets crushed into singularity and stays there, but lots of physicists say that the singularity isn't a real result and just a sign that our physics models break down at that point. I think quantum physics makes the creation of actual point-singularities impossible. We need a unified theory of gravity and everything.

Maybe it's similar to flow into other singularities. The ocean (earth has just 1 ocean, regardless how we name it) is an example. Water flows in. Then where does it go? If you ignore the environment you say 'nowhere'. But we know that's not true because eventually all the water would be in the ocean.

In reality it "comes out" in coastal groundwater, and by evaporation, and in ice caps, and even in complex life forms. It's only when you recognize the different forms of water that the cyclic flow becomes apparent.

Assuming Occam's razor works on a universal scale, I'd go with there being a cyclic flow of light/matter (in different forms/phases) between the black hole and it's environment. To me it's 'more acceptable' than having stuff just disappear down the drain. Of course, I'm an avid re-cycler so I may be biased.

Now if I could just figure a way to use my 120mm refractor to prove all this....

IMHO, I don't think one can assume that "it must be coming out somewhere" just because it's going in. For example, the idea of BHs being the entry point to wormholes with an exit somewhere or somewhen else in the universe remains speculative. Furthermore, the rate of Hawking evaporation is so small that it can be disregarded for all time scales less than trillions of trillions of years. BHs would be subject to the same laws of orbital mechanics as any other object. That implies they don't suck up matter any faster than any other massive object, and that less massive objects can remain in stable orbits around them for billions of years. The fact that galaxies do not disappear into their central BHs, despite huge masses, is the case in point. What distinguishes BHs is that they have **serious** gravity well gradients that distort local time and space to the degree that mass inside the event horizon is undefined, save for mass, charge, and spin. One could as well speculate that inside the event horizon is a world where fairytales really exist. Cinderella remains at the ball, because the clock never strikes twelve. Of course, you could never get that information to the universe outside the event horizon.
