The biggest obstacle of science is "knowing" before we know The Standard Model, The Big Bang, The Law of Gravity, a finite but expanding universe... all scientific theories widely accepted.. leading to string theory, etc... but how often must new discoveries twist and turn us to different and sometimes opposite directions in the field of science? Please refer to my subject title again at your convenience. When mathematics is used to prove physical theories, I see a fundamental flaw that is overlooked in our eagerness to "know", that is that equations will always result in a finite # thus we have a finite universe, in such, math is not capable of defining reality and leaves out possibilities, of an infinite universe that isn't expanding (but looks to be expanding from our little perspective here on planet earth) but may be just moving outwards from us in all direction, as what would be possible in an infinite large universe.. as if space and time (the concept) can somehow have a boundary.. it is our minds that have the boundry. If the universe is expanding then what is it expanding into, nothing? Dark Energy is exponentially pushing the universe outwards, but we don't even know what dark energy is, its just a term to explain something that we don't know but everyone is eager to jump on because it has a nicely packaged name. Its heretical of science to assume something before it knows.. but this seems to be the case many times over, even though our observations add up to neat explanations that work but there is always something missing.. an infinite # of unknown possibilities will cause this as there must be this scenario when we do not have the total picture... but we never will.. why should an infinite universe in space and time with no origin ever be ruled out? Where does logic begin to escape us? How can there be multiple universes for one, the universe is a word used to describe something and in this case, the word describes the totality of all things known or postulated, so to believe in multiple universes means we don't even have words that are standardly used in science let alone urbandictionary.com When words don't mean what they mean anything can mean anything so what the heck am I talking about, right?
