Time dilation is in fact about perception. Archangel is right. Someone traveling near the speed of light perceives time at the same rate us slower mortals do. BUT this is because everything around the speeding person is smaller, due to length contraction. To the person, everything is as big as it always was, to us, they shrank. ALSO the person moving at speed perceives US as moving, not themselves, and sees US shrink. There is no method for either party to identify whom is ACTUALLY moving, a third party is required for this.
Energy conservation must always exist. If not, then the same event that caused the big bang would wipe out all matter. But even this is conservation, because the net energy change is zero! Suns explode all the time, so why do you insist that the big bang was the creation of energy? The big bang was more likely the explosion of a Super Sun, causing a chain fusion reaction creating a universe full of matter.
FINALLY, Archangel, kinetic energy cannot exist of its own accord. That requires empty space to move, meaning that energy is not bound to matter, meaning this "free" energy could be harnessed as a limitless power supply. It has been proven that there is no such thing as free energy. Chemical energy is part of matter (food for example), so CAN exist of its own accord. (unlike kinetic, gravitational and elastic)
These are the facts used to form my theory about the universe, and since energy conservation must apply, perhaps time (bound by the existence of our universe) loops through the cycle of a massive sun exploding and reforming (much like the air returns to the center of a nuclear blast, resulting in the mushroom cloud). So in my opinion, time never began, it just always was, is and will be, and perhaps we get a second try.
