[QUOTE="JTA, post: 384606, member: 191063"] when observing light from distant galaxies, we ARE looking back in time, simply because the information provided by these photons took a long time to get here. Say that you ordered a book on the latest technologies in quantum physics. If it took that book one year to be deliverd to you, then you would have a book on the latest technologies one year ago. It wouldn't tell you anything about the current state of these developments, as we can't tell anything about the current actual state of these remote objects that we're observing right now. Ah yes, and time didn't start with the big bang. Time has allways existed and will allways exist. Our universe may have started with teh big bang, before that there was just "space", or "M-space" as it's called now. Can you travel outside our universe ? I think not, as it's expanding at light speed, and nothing can travel faster than light. So all you could achieve is to keep up with the expanding universe, without being able to catch up with it. And even if you succeeded, you'd be in "empty" space, untouched by our universe. This space would be depleted of everything, at absolute zero, with not even a photon to pass by from time to time. Yes, boring indeed. [/QUOTE]
