Ok so like, say theres this ultimate space, its black, and it is infinite... it literally goes on forever, and there is nothing outside of it. Something has been in it this whole time, accept that its time that makes the something want to become more of what it already is. Take evolution for example, you know how when the planet first started to create life, and how long on the universal time line it took for things to take off, from the beginning of the formation of our planet to now.
Many scientists claim (through rigorous study and experimentation) that this planet is about 4.55 billion rotations around the sun, and that it took anywhere from .5 to 1 billion years for the planet to become inhabitable and for life to gets its foothold on this paradise.
Now, when you take a look at the scale of evolution you see that the longer "time" is around, the faster somethings want to become something more. For example, this planet has been around for billions of years, humans have only been around for a mere 200,000 years if that. Out of 200,000 years... only 200 of those years were spent creating the technology that we have today. From cars, to computers, to phones to roller coasters. Technology we use for work, and for play.... only 200 years out of a 200,000 year human history.
As the universe has told us, and is easily viewable through our new found technological advancements, that evolution indeed does happen, its happening all the time. The thing is, that as time passes... evolution seems to get more and more rapid, seems to get faster and faster. (accept that when evolution isn't necessary for continued existence it seems to slow down for some reason)
Say the existence in general had already been, and has always been... its just that there was a time when there was only a little of something in the space. As time passes, maybe that something for some reason or another wanted to be something more, so little by little that something found a way to grow bigger, eventually multiply, creating strings, circles, atoms, molecules. Maybe the first something actually was a black hole, sucking in every little peice of something in the space until KERPOW!!! All the information gathered into the black hole by chance, just seemed to fit, all the puzzle peaces formed together in such a way that the first universe was born, with laws, physics, gravity, everything in place in order for this universe to not collapse, or crunch in on itself.
As time passed, this universe... which is expanding by the way, evolves to give itself black holes within its galaxies. As time goes on the black holes gather up the ingredients for another universe. When the time is right, and the black holes have gathered enough energy, POOF! Now remember that ultimate infinite space, the one that the first black hole was in, that created the first universe? This is the space where the other universes that are born reside.
Why don't the expanding universes bump into eachother as each universe is expanding in the ultimate space? Well, since the space is infinite, as the universes expand, they get evenly distributed within the space to make sure that no universes bump into eachother, as each grow bigger, the space between the planets is increased.
I think someday that our universe will collapse in on itself, kinda get recycled in a way i guess...but i really don't know ANYTHING. Like, i think i know stuff, but really when it comes down to it... i don't know shit about what the fuck this reality is, or what the fuck is going on right now. Mushrooms help me cope with this feeling, makes not knowing easier to bare.
Come on science, lets figure some more stuff out soon before i die, i want to know if we live in a multiverse.
