What's your speculation for what happens in a singularity? Personally, I've always kinda hoped they are inter-dimdensional portals, and they'd spit you out in a different galaxy... I mean there's a smb in every galaxy. It just makes sense... but more it's more likely that I'm just crazy. Oh and I have another thing... so in Star Trek, they have warp speed, which is faster than light travel. If you are moving faster than light, and you travel for, say 5 minutes in one direction, then stop and turn around, wouldn't you see yourself from before you traveled faster than light 5 minutes ago?

  • A dimension is a measurement. A line is one dimension, a square is two, and a cube is three. A singularity is zero-one dimensional. Don't think of "different dimensions" as in "different universe." But no, I don't believe that to be true. A black hole is a just rip in space time. Don't think of it as a hole per say, it's still a spherical object, it's just that light cannot escape. It doesn't lead anywhere, it won't teleport you anywhere, it will just rip you apart and eventually evaporate. A black hole has two intrinsic properties: mass and spin. That's it. Black holes are actually pretty boring objects, what science is interested in is what happens [i]around[/i] the black hole. And the singularity is just nothing we can even talk about. FTL travel is fine, if you're not actually traveling faster than light. Like, galaxies do it all the time, as they're not moving away but space is expanding at a faster rate than the speed of light. So, if we can manipulate spacetime so that we could travel that fast, then yes it's possible. And presumably yes, about the looking back thing, although I'm not sure if warped space time would change this matter.

  • Okay I have one more for you if you're up to it: What are you're thoughts on the break in symmetry in the early universe with the formation of particles and anti-matter particles? Could it have something to do with black holes?

    No. Quantum fluctuations cause energy to clump, which breaks spacetime symmetry and separates GUT from gravity, as the universe expands the individual forces come into play, these forces allow for baryons to be created. Black holes form through stellar evolution, baryogenesis happens way before stars can emerge. Baryons and anti-baryons annihilation had to stop due to the process of CP violation before recombination could occur, and recombination had to occur before structures like stars could form.
