Ok I'll be clear that I made an omission by not using the word "observable". I should have. Congrats on the gotcha moment.
Edit to previous: If you understood the basics surrounding the size of the observable universe, the speed of light and time, you'd conclude that intelligent life elsewhere in the universe is a notion already refuted by logic and math. You don't, so you think aliens are possible.
As I have stated in other parts of this thread, things like parallel universes cannot be dismissed. They are also unrelated except for the fact that they usually capture the interest of the same alien loons that talk about UFOs.
Pro tip:. If you'd like to discuss the mathematics regarding other dimensions and/or parallel universes don't muddy the waters and soil your credibility with the absurd notion of aliens in this one.
