Gotta say that my idea requires us to assume both that the BB is just a cosmological event and that space is infinite and that our universe is expanding into "something". Both of wich we have no evidence for. The extremely dense, extremely hot state that our universe started as could be the byproduct of two hypermassive blackholes colliding. Black holes merging together produces a massive amount of energy that could form primordial particles and eventually the very matter our universe is made from. But as i explained, it would require two objects that have a mass way above that of our universe to produce such an event. Basically my idea explains how our BB was caused by the collision of two massive objects. Sorry if i glanced over a lot of details, i wanted to make it short but it lacks a lot of clarity. Our lack of evidence suggests that our universe is innately positive in particles (there are more matter than antimatter) My idea and other theories propose a model of a multiverse in which there are regions of space rich in matter, and other regions rich in antimatter. Other theories say that matter forming at a higher rate than antimatter is an innate property of matter itself. For my idea i stick to the former. Although i will drop the parts about antimatter, as it is irrelevant to the BB event. My idea proposes that the universe started out as a quantum vacuum. Sometimes virtual particles would interact with each other and form a stable state. Given an infinite amount of time, that matter would eventually coalesce, much like how gas>stars>galaxies>clusters. And much like how objects like galaxies and black holes can merge, that matter would form into more and more massive objects. The BB would be a consequence from the collision of two of those objects. Even the existence of life in such a system would support such an idea. While there are matter that coalesces from a vacuum, only a rich environment like that produced by a BB would allow the production of enough stars, and thus, heavy elements, essential for life. Maybe my idea is just a wild guess, I'm just trying to make sense of it all. But as pointed out multiple times in replies, current models are based on evidences, and my idea would require us to make observations that are either hidden past the edge of our observable universe or too redshifted. The infinite void would be a state prior that that of the BB. My theory doesn't exclude the big bang, it just states it as a cosmological event. Sorry if i glanced over the formation of the hypermassive blackholes i mentionned. If the universe prior to the BB was much less dense than that of our observable universe, i'm not too sure if there would be stars and galaxy forming, but eventually all that matter would coalesce, and possibly achieve such mass that they'd become black holes. So basically, my idea proposes that the universe prior to the BB is just space filled with black holes. From what i've read, two black holes merging also produces a burst of energy (plus gravitionnal waves), unless i'm wrong, which means that i was misled by the sources i've seen, and my idea crumbles. If two objects had enough mass and came into contact, they could produce an amount of energy that would be on par with that of the big bang. My idea just expands on events prior than what our observations can tell. Hm, i don't have enough knowledge about the rotation curves of galaxies. But if our universe were to orbit an hypermassive black hole (or Nemesis as i liked to call them) maybe there would be a correlation. I know that the Dark Flow theory points toward a point in space outside of our observable universe, although it is debated, but maybe this is further support for my idea. Btw thanks everyone for the quick replies.

So far the Big Bang theory is the most solid explanation for the birth of our universe, but i always found the idea of a singularity instantly spewing out a massive quantity of matter was uncanny. So i pondered upon it for a while, and came up with a theory that would explain events prior to that of the Big Bang, based on what we know about physics so far. In this theory, the Big Bang isn't t=0, but just an event in space. Just a quick warning first: I am no physicist, i am just an amateur that daydreams a lot and think about stuff a lot. Also english is not my native language, so i apologize for any mistakes. I also invite anyone and everyone to poke holes, deconstruct and falsify my theory. If not, to provide help on how to better construct it. Thanks! So here it goes: Snowball Universe: The Universe starts out as an infinite void, with nothing but infinite space and virtual particles popping in and out of existence. On really rare occasion, bits of matter will clump together. I'm going to refer mostly about matter, but you can assume the same happens for antimatter too. The clumps of matter will interact with each other and merge. Clumps of matter that come into contact with clumps of antimatter won't mutually annihilate each other. When their surface come into contact, the burst of energy released will make them "skip" against each other. Much like how the Leidenfrost effect works. Clumps of matter will keep on getting bigger, eventually forming objects with a mass equal to that of a black hole or greater. This hapens in an uniform pattern in the infinity of space. Our pocket of the Universe starts when two black holes with each a mass vastly superior to that of our observable universe came into contact. I'm going to refer to those hypermassive black holes as "Nemesis". The collision resulted in a massive burst of matter, to which we attribute the Big Bang. Instead of being a singularity, it is actually a collision point. What this theory explains: -Where all the antimatter is. Our Universe is an agglomerate of matter. If we could peek further into the Multiverse, we could see agglomerates of antimatter similar to ours. -The missing mass in our universe. This theory explains the mystery of dark matter, the gravitationnal anomaly actualy comes from the Nemesis. -Where our Universe came from and where we are headed. This theory is based on what we already know about space and particles. Matter has a tendancy to clump together, and the Nemesis will keep on getting bigger and bigger and merge with each other. -The actual Multiverse is much less dense than our Universe. Our Universe is just an agglomerate of matter around a Nemesis, much like an accretion disk. If we could zoom out and see the whole Multiverse, it would be similar to our Universe, less dense, and instead of galaxies, it would be made out of multiple pocket universes made of either matter or antimatter. What we could look for: - Remnants of matter that orbited our Nemesis from before it's collision, the Big Bang. Since the collisions are really rare events, chances are that whatever matter was left was in a state close to that of "Heat Death". That matter has possibly merged with that produced from the Big Bang. -Presence of other universes or antiverses. If their existence is real, their light has probably reached us, but has probably redshifted to the point that we can't perceive it with our current technology. -If we really are orbiting a Nemesis, we should be able to detect its gravitationnal field and its effect on objects around it. Our universe should also begin to form an accretion disk around its Nemesis. -The possible "death" of the Multiverse. The Multiverse started with virtual particles merging together into clumps of matter and antimatter, and has been growing since then, at a very slow rate, even astronomically speaking. Either the Multiverse will reach an equilibrium in which it's growing density allows enough interaction between matter and antimatter to balance the creation of new matter, or it will keep on growing, becoming denser, to the point where the infinity of space itself is filled with mass with a density similar to the core of a black hole, at which point it will either stay completly filled, or will instantly vanish from all the matter and antimatter being forced together, starting the multiverse anew with a complete void.
