thats really a horrible perception of aliens. why would u think that we are the only developed organisms out there, for all u no aliens could already be travelling at the speed of light. well maybe not.
just a question, which do u guys prefer, the big bang, or the steady state theory, if it is true that there is nothing beyond the universe, and the universe is infinite, then the steady state theory seems to take the cake on that.
just as a clear up of both theories, although its not perfectly defined, cause im not exactly sure of the words to use.
Big Bang Theory: basically there was a point in time where time was 0, and the universe came out of nowhere, slowly expanding and growing, something along those lines, and will keep on expanding.
Steady State Theory: The univers never came form anywhere, it was just there. and when it seems to expand, what happens is as lets say these parts of the universe (i e galaxies) move apart, their gravity creates mini-universes from the matter in between, so lets say Billions of years from, now the universe is as dense as it was billions of years ago.
i hope that wasnt completely incorrect.
