I’ve heard some talk lately about Black Holes being used a gate to another part of space. Let’s be straight, I’m not a physicist by any means, but from what I do know, it’s rubbish.
Now, wormholes are still a valid theory on paper, but here’s the snag: they’re really, really small. Horrendously small. Quantum small. Next to nothing could fit through these little rips in quantum-foam, so they’re effectively negligible. Expanding them is effectively impossible, as it would take techniques that we haven’t discovered, cannot exact, and probably require an insane amount of energy.
This leaves a rather large hole in my argument: what about inside a black hole? We don’t know what goes on in there, so by the logic that makes Schrödinger’s Cat work, it could quite possibly exist. We could even scratch off one of the requirements above, as where infinite mass is not only possible but in fact present, massive amounts of energy and defiance of common physical laws are no longer an issue. Except here’s the next issue:
We will never definitely know that this works. Observing a black hole is impossible, partially because they’re so far away that they are a challenge to see as it is, and mostly because the contents of the inside of a black hole are in perpetual darkness, as all light that passes the event horizon is devoured. They way we’ve found them is comparable to finding an animal’s tracks rather than the actual animal, but that’s somewhat irrelevant right now. The real point is that if the escape velocity for a black hole exceeds the speed of light, and the maximum speed limit for matter is 299,792,458 - (1/∞) meters per second, just shy of the speed of light. Thereby, even if you traveled top-speed directly into the singularity at the heart of the black hole, you literally couldn’t enter it fast enough. You’d be destroyed. I can’t even explain this at this point, but it’s relatively safe to assume this, as while traveling just shy of the speed of light, you collide with everything that isn’t. The black hole would probably pull your ship apart, as a singularity with infinite mass means has an insane gravitational pull, and the fact that the singularity exists alone is proof that physics get kinda weird when this kind of thing happens.
Well, what if you could exceed the speed of light?
Some say they’ve found a way to beat around the bush here by expanding and contracting space (space is not matter, and as far as I know no intrinsic properties, so if you can distort it fast enough to travel faster than light, that’s a valid loophole, right?), and although I still find it a bit sketchy, I’ll let it slide. Except that we don’t have the energy or materials to develop that either, so scratch that for now.
Two more thoughts occurred to me:
1. A black hole isn’t a flat portal through space and time (boo on Star Trek XI for that one). It’s more spherical in nature, although, it does have a massive debris ring. The actual “black hole” is the space within the singularity’s event horizon, where physics start to get weird. What would the other side look like?
2. If a wormhole opened up at the other end of a black hole, you’d have a straight shot to another part of the galaxy, except that the gravity from the black hole would pervade that region of space that it opened up to. So now you wouldn’t have a black hole sucking in matter, and a so-called “white hole” ejecting matter, you’d have two black holes. Which are actually in truth the same black hole. Physics.
Again, I don’t claim to be an expert. This is just me putting up my reasoning process for the examination and critique of others. These photos are not mine, credit to those who produced them.
