I have been thinking about something called String Theory. In my opinion it is a very loose theory that will need a lot of work (it should be noted I am NOT a physicist, so please if there are physicists reading this comment and tell me why I am wrong and why this theory should work). I was listening to Michio Kaku (you can find his video in my Fun Media page) about the theory of everything, which he said encompasses what String Theory is trying to explain. If String Theory is to be proven, it will be the most remarkable discovery in the history of the human race. My problem comes in at the theory of a Multiverse. It says that there could be more than one universe and we are in one that makes up a Multiverse. We have observed galaxies (much like ours) that have collided with one another and formed a larger galaxy. Why is this important to the Multiverse theory? Well the physicists who are working on this say that one universe can collide with another one. However, this collision would cause a Big Bang. This shook up everything that I have been taught about the Big Bang because Stephen Hawking said that there can be nothing before the Big Bang. So where did this other universe come from? It is possible that my knowledge of the Big Bang is outdated and I need to do more reading and research. If I find that to be the case this post will either be updated, or I will write another post. Back to the theory of the Multiverse. So where are these Universes coming from? If the Multiverse is correct how can we know which is the original Universe? Where did the original Universe come from? If the Big Bang was a result of two universes colliding, what spawned the first Universe? I understand modern science cannot answer some of these questions yet (or my hypothesis that I need to do more research is correct) but are working on it. String Theory has not yet been proven so I am eagerly waiting to figure out the results (hopefully in my life time). Another theory I heard is the theory of wormholes. The idea of a wormhole makes a lot of sense. Take two dots on opposite ends of a sheet of paper. If someone challenged you to put a pin through both holes, what would you do? The answer would be to fold the paper so one dot is on top on the other.
Theoretically this would be a way to travel in between Universes (given the Multiverse is correct). Michio Kaku gives us an equation to explain String Theory. This equation also questions the possibility of surviving a trip through a wormhole. We cannot yet experiment with wormholes so we really have no idea if wormholes are possible, or if we can travel through them. It is a very interesting thing to think about. It is also exciting to think about.
I do have one worry about this. The Universe we live in now is heading toward a freeze out. That’s right, eventually the Universe will expand (as Hubble discovered the Big Bang is still happening and the universe is expanding) so much that it will freeze everything. Stars will be blown out and all life will die. Assuming that we escape the fate of Earth (that is being swallowed by the sun once hydrogen fusion ceases in the core, the core will collapse, and the sun will begin to fuse hydrogen outside of the core, then the sun will expand into a red giant that will basically swallow the earth) and find another planet to live on until this freeze out. Let us assume this is true, our only escape from inevitable death will be to travel through a wormhole into a younger Universe and to start over (assuming we can find a suitable planet). My worry here is that, in the interest of self-preservation, people will have a need to prove this. They will have a need to prove String Theory so much that they might fabricate details. It is a terrifying thing to think about. Everything in the Universe will die. We cannot escape it if we stay in this Universe. I can’t even pretend to know everything about String Theory because I only know a little (a very small amount about this theory).
I really want someone who knows more to comment on this and help me understand something that I may be missing above. Please let me know!
