well
its a couple of "scientific facts", nothing really new but its nice to watch it^^
i still think that the universe hase no scale, i believe that space and time are curved so hard at his "edge" so that it hase no real scale, it also could be that if you reach the end "on the left" you will find yourself at the "right end" and so on..
its just annoying to write or talk about this, thats why i belive in god - not just because its hard to imagine the universe, just because there are questions science cant answer, for example the beginning of the universe, and the fact that the atomic model we are using is just logical when we use it for simple chemical reactions and radioactivity, but when scientists reach more complicated areas the whole thing seems unlogical
science is just a try to explain everything, some things are right, but the most funfamental thing cant be answered with out way to think. and humans can be very creative when it comes to explain something they dont understand ;D
