There is a theory about the universe expanding. They say eventually, it will stop expanding, and inevitably begin to shrink again. Once it culminates in the center, a "big crunch", the opposite of the big bang shall occur. Then, ANOTHER big bang will happen, and the universe will start over again. Monkey's are incredibly intelligent. Gorilla's can have IQs nearing 100!Even at the speed of light, it would take years to reach the nearest star (aside from the sun)It would take 8 minutes (roughly) at the speed of light to reach the sun from Earth.Black Holes can't actually be seen. They are so dense, they trap everything with their inertia. Even light can't escape, so we can't actually see them.Its true, your head can survive indepedantly for a short time. (Without special conditions though, its only a few seconds)Chances are, if every religion on the planet is even slightly right, then if there are such things as "aliens", then they aren't as advanced as us, and are probably making scary films and having nightmares about US.
