  1. Quite the contrary. Your perception of the universe is actually sped up immensely. It's confusing, but because you have a slower clock than the rest of the universe, the rest of the universe would see you slower, but you would see the universe faster.
  2. That was a very interesting article. Wow, its an intriguing concept, the firewall. I'ma have to take a break from watching theories about resolving quantum gravity.
  3. As seen by the person falling into the black hole. If you were an outside observer, everything would be normal, there would be no time dilation, unless of course the outside observer was travelling close to the speed of light.
  4. For K^2: Yeah, there has been no concrete proof for Hawking Radiation. There have indeed been tests to find evidence of an evaporating black hole, specifically one in its final death throws, in order to find evidence for primordial black holes. However, we do know that subatomic black holes have formed in the LHC (probably/maybe), and they appear to have evaporated. - - - Updated - - - For Bill Phil: You are correct about the thing with entropy. Black holes would violate the laws of thermodynamics (I'm pretty sure that you people know what they are) because they appear to decrease entropy in a supposedly closed system, the universe. Thus the universe is not a closed system, or black holes radiate something. P.S. If anything in here is incorrect, I'm sorry. I don't remember everything from all of my physics books and A Brief History of Time.
  5. For Bryce Ring: Steven Hawking proved that black holes evaporate. The idea is that pairs of virtual particles, an example being a positron and an electron paired, pop into existence because their energy is borrowed from the vacuum, and then annihilate soon after. However, if these particles form close enough to a black hole, the antiparticle can fall into black hole, and the other particle escapes to infinity. From an outside observer's point of view, the black hole will have emitted the particle. Smaller black holes will evaporate faster because of things to do with smaller operational surface area of the event horizon and the black hole's mass.
  6. Well, I was thinking about this, mainly about the fact that as you are falling in, the black hole is evaporating faster and faster from your point of view, so it must evaporate completely before you reach it, and I came up with something quite interesting. As you are falling towards the event horizon, the region of space that is closest to the horizon, the place where the virtual particles that matter would form, would appeared drastically slowed. This is because they are obviously closer than you are to the black hole. But does the time dilation of this region actually effect the formation of the particles from the vacuum energy? If it does, than to any observer outside of the event horizon, unless they are at it, would see the particles forming more slowly, and thus it would take even longer for the black hole to evaporate. And, If you are, once again, an observer falling in, than the black hole would decay more slowly than usual until you pass beyond the tiny layer beyond it, and unless time dilation is significant over such small distances, you would fall into the black hole possibly before it decays. That last part also brings in the question: Will the time dilation increasing as you get closer and closer to the black whole kill you anyway, as different parts of your body have different clocks?
  7. Okay, so here is my question. *NERD MODE ENGAGE* So, as some of you know, high gravity fields can warp time, due to the effects of relativity. This effect is so extreme near black holes, due to their gravity, that an hour close to a black hole can be a thousand years on Earth. Now, as an observer falling into the black hole, as you looked out you would see, in the little disk that is the universe around you (gravitational lens effects) you would see it aging and dying, faster and faster, until you pass through the event horizon.. Once you passed the event horizon, you wouldn't notice anything different, you would just keep falling until you are spaghettified by the gravitational forces. However, at this point, you are closer to the singularity than the virtual particles around the event horizon. These are the particles that contribute to Hawking radiation, and eventually cause the black hole to be destroyed. As you are closer to the singularity of the black hole than the virtual particles at the event horizon, they will experience a faster time than you do. Thus, you would expect the black hole to be destroyed as the particles take away its mass faster and faster from your point of view, possibly even before you are spaghettified. Therefore, you would be witness to the death of the black hole, and would likely be killed in the final explosion, due to the effects of the black hole itself. Whew, that was an explosion of science. *NERD MODE DISENGAGE*
  8. What happened to this? Has it moved, or is it gone, or am I just an Idiot who is a newb at fourums? Im just really, really new
