I've been studying sciences since I was a child, and I'm fairly certain every mention of a singularity leads to the big bang and the creation of the universe. I don't understand why though? There is a black hole and potential singularity at the heart of every galaxy. So why have I never heard any postulation about galaxies being created and destroyed by black holes? It is always a star system that is lost and a universe that is gained. I may just need to read more, but I find it interesting that I have never come across this. The universe is expanding. We know this with certainty. If everything was created from a singularity and propelled outward by an unknown force for unknown reasons, (I believe the mass simply overcomes stability and pulls matter towards its gravity center and through itself. Stand in the middle of two carts on wheels and pull them toward you at the same time as hard as you can. They dont stop at the source of what pulled them. They continue through and past.), and this resulted in the universe, than how did the first singularity form? You have to assume it was created as we have observed them created, which means it began as a star. Stars are formed by clumped masses of gas and matter compressing and essentially combusting. Everything about the very concept of a singularity forming the entire universe is illogical. I don't think I have the answers but I do think we are all taking the wrong test. What would happen in a model of galaxies that form singularities which collapse and expand? Could "the mysterious force" that causes universal expansion be explained by galaxies exploding? Or how about the odd shape of expansion previously written off with gravitational bodies? For myself, gravitational bodies seems like a logical conclusion, just as, I can see water in my street right now. It would be completely logical to deduce that the water is coming from my neighbors sprinklers, however, looking past his property, I can see more water. Am I now to believe that his water went uphill? There is another force beyond what I see here. Most likely another neighbor. No real mystery, but I hope it helps to illustrate my point about universal expansion and the current explanation thereof. Was the big bang really that big? Maybe is was more like a medium bang? What if there have been trillions of these black hole emissions? What if celestial bodies and atoms behave similarly with the exception of celestial bodies being constantly subject to super massive waves of gas and matter as a result of a violent force? That's a huge stretch but I feel like physics is locked into a unidirectional thought process. We assume everything is absolute. If the universe is infinite, why do we bind ourselves to law. Mechanics that work in our star system may not hold true in others. So why limit our thinking to a very limited set of rules that are almost always broken with new discoveries?
