criscodisco posted:Lol how the gently caress did you know that? I think black holes are pretty cool too. I always liked the idea of time showing way down and I wonder if your brain can somehow work faster than time and you get a millenia of starting at a black hole and being alone with your thoughts. That sounds pretty awesome. afaik, your experience of time would be perfectly normal for you (you wouldn't get to "live longer" and if you had a watch on, it would tick normally). However in certain circumstances, you could be right near the event horizon and time would slow down for you so much compared to someone outside the black hole (their watch would be ticking super fast as you observe it, and your watch would be ticking super slow as they observe it), that you could "see" the future of the universe unfold before you. Of course then you would get sucked in and your feet would stretch out far below you as you are pulled part... Sophy Wackles fucked around with this message at 21:59 on May 1, 2016 |

Also how could I see the hands on their watches spinning? Wouldn't the photons making their way to my eyeballs also be slowed way down?

A black hole contains a universe inside. Our universe is a black hole. It's a "singularity" in that nothing can ever escape and nothing can ever see inside. That is why 0 is a circle. 0 doesn't mean nothing, it is a circle that represents the set that contains the entire universe, which is the equivalent of a singularity, or 0. Also, .99999 = 1.

Decebal posted:Is there anything in the Universe more fascinating and terrifying than Black Holes ? NO there isn't ! Here on Earth if I die at least my atoms will be recycled into other beings, rivers , a tree, etc. But if you die in a singularity you don't even exist in this Universe anymore. Lol op I can answer all these questions. You got the first one right: black holes are awesome. Scientists have an explanation for the existence of black holes: gravitational collapse. If there is enough mass in the core of a star when it goes supernova then it will collapse into a black hole. The only place where we don't know what's going on is at the singularity. Black holes can spin yes, actually I think most black holes are rotating. Because they come from a star which was rotating: angular momentum is conserved. Rotating black holes have oblong shaped event horizons which are stretched out on the plane of rotation. They also have this region called the ergo sphere wherein it is impossible for an object to maintain an orbit. They can move through space same as any other object in the universe. Yes one could just show up in the solar system and I'm pretty sure it would result in everyone dying because earth gets flung out of its orbit or something. You can pass the event horizon easily and physics still works fine. If you pass the event horizon of a supermassive black hole you may not even notice (besides all the hosed up light physics). Things break at the middle, at the singularity.

In your local frame of reference everything is "normal". The spaghetti thing happens because of the gravitational force increasing super rapidly as you get close. Like the ops picture, it is a "cliff". A local inertial frame of reference is where space-time is mostly flat in your immediate proximity. When you get close to the black hole, space-time is changing so fast that your body is bigger than the characteristic size of the reference frames.

The EH is where you can't escape anymore. It looks cool from the perspective of a distant observer though. They will never see anything actually go past the horizon. Everything just slows way down and takes infinite time to get there. https://www.youtube.com/watch?v=eI9CvipHl_c

I read somewhere that since a black hole pulls in all light and you can't see it, the only way to determine it's there is to look at the gravitational lensing effects where it bends light like like a glass lens but doesn't actually pull it into the black hole.

That is precisely how they are detected. You can also infer their existence by measuring the orbital parameters of some stuff and finding that the only thing that could explain it is a black hole. Also all mass bends light. They use gravitational lending to measure stuff in galaxy clusters.

black holes are pretty fascinating because all the stuff we know about physics and science completely break down when we try to study black holes or something like that. also i saw once in a movie that the only thing which can escape a black hole is the power of love

You can also look at the motion of stuff around it. We discovered the supermassive black hole at the center of the Milky Way by watching a bunch of stars orbiting a point that seemed to be empty. The orbits are so tight that a very heavy black hole is the only explanation. E: Yeah.
