Another thing that I would like to be enlightened is reagrding to the speed limit of the universe.Correct me if Im wrong. Nothing goes faster than the speed of light. Theoritically if your on a space ship as you approach light speed time slows down. Upon reaching lightspeed, time stops. So grating that we will equate lightspeed as zero in a number scale. However if granting you can really go faster than the speed of light, time goes backward (like a time machine going back to the past).Now in relation to the above, the big bang started from something infinitely small and expanded (exploded) to something like the size of a ball in a billionth of a billionth of a billionth of a second. Thus Its effective expansion rate was moving way faster than the speed of light.So if my understanding was correct, what happened to the Law of Physics regarding the universal speed limit? Secondly, moving faster than lightspeed, wouldnt that expansion comes in a loop?

It doesn't take a person with a high IQ to understand that time itself does not stop or move backwards just because the person is moving faster than the speed of light.
I don't think it's possible to travel back in time as far as we are concerned. This shit is way over my head though.
As I understand it, travelling faster than the speed of light (which isn't possible anyway) would only cause you to 'catch up' with images of an event that happened in the past: You wouldn't actually be travelling into the past, but would simply be overtaking and observing previous images of the event. So you might see a person appear to grow younger, for example, because you are exceeding the speed at which current images of that person are eminating, and catching up to those which have gone before.
Well, time dilation is a theoretical concept which (supposedly) only occurs at extreme ends of the physical spectrum. For example, at the event horizon of a singularity / black hole. Probably such events are beyond human comprehension at this stage, but I guess they're worth speculating about nonetheless.
Similarly, you can say you 'measured' the effects of time dilation, but does that mean you can say you understand it?

Else the prediction couldn't have been accurately made.To me, that's an important disctinction.On the other hand, yeah... Feynman said, "I think I can safely say that nobody understands quantum mechanics."
Well like they say, your guess is as good as mine.
