10: How was the multiverse/universe created?
Scientist can now basically backtrack the creation of the universe through mathematics. We know how fast light travels; it takes about 8 min for light to travel from the sun to the earth. So, if the sun were to go out all of the sudden, we wouldn’t see that it had for 8min. That’s the reason why we use the unit light-year for distance. If something is one light-year away, it would take one year for a beam of light travel from it to the observer. This also means that if we look at something that is one light-year away, we are seeing events that took place one year prior. The next part of the puzzle is to understand the current expansion of this universe, which we do. Reversing the pattern of its expansion, gives us a fairly accurate reading of its origin, about 15 billion years ago. I call this the universe, the place where we exist right now. Do other universes exist? I don’t know the answer to that off hand but I do know that it is fair to assume that they do. Therefore, I use the te...
