What was there before the Big Bang? Well, you see, there was no ‘before’ because before the Big Bang time did not exist. Time is a result of the expansion of the universe itself. But what will happen when the universe has finished expanding, and the movement is reversed? What will be the nature of time?
If string theory is correct, the universe posses nine spatial dimensions and one temporal dimension. Now we can imagine that in the beginning all the dimensions were twisted together and during the Big Bang three spatial dimensions (the ones that we know as height, width and depth) and one temporal dimension (what we know as time) were deployed. The other six remained minuscule, wound up together. Now, if we live in a universe of wound dimensions: how do we distinguish between illusion and reality? Time, as we know it, is a dimension we experience only in one direction. But what if one of the additional dimensions wasn’t spatial, but temporal?
I often have this dream, in prehistoric times, I can hear you screaming. I chase the bear and you’re not afraid anymore. But when I wake up, there’s no bear… but you’re still afraid. I’m not a bear hunter. I’m an executive at a plant that manufactures photocopying machines that just quit his job. I don’t dare move, not live, whatever I do is a disaster. I would set out to chase the bear away and for you to not be afraid anymore.
It is terrible. Hot chicks with weapons makes up for it though. What did you think? Source Code. Watch it!
