Origin of Matter: Theory Explaining Creation

[Kristiandhd]

Matter doesn't occupy every fraction of space within the universe, it is merely spread out approximately homogenous everywhere. (Meaning that it clumps together into galaxies and stars and such, but on the largest scales it is homogenous.) If the universe is infinite in extent, and the average density of matter is the same everywhere, then there is an infinite amount of matter spread approximately homogenously throughout the entire universe.

Matter was not created from nothing. All the matter in the universe today was created early in the universe by interacting high energy photons. Where the ultimate origin of all of this was is unknown and probably isn't capable of being known. Any talk of where spacetime came from is pure speculation at this point.

but if you state that it was dense in the beginning through out the whole universe, and space-time being infinite for it to be spread out across some what evenly through space-time then there would be an infinite amount of matter? for if it is finite there would be an infinite amount of empty space time.
and isn't there multiple theories about where matter came from and coming from nothing is one of them. one being the collapse of other dimensions, and i think one where waves in space time collided to make it. (though i find it unlikely since what created the wave in the first place.)

but do you agree that if space started, and hasn't been around forever, then matter had to have come from nothing since space had to appear first for matter to then occoupy it, since matter can't simultaniously appear for that would mean it appear nowhere since there would be no space time for it appear in. correct me if I'm wrong but isn't that the idea of the singularity that the universe just appeared.

and i accept my ignorance in my point of view, I'm merely trying to understand it better, you seem 100% certain of your beliefs, and maybe up until now you are as correct as our current knowledge allows us to be. i don't know but if you are then i'll try and learn.

There is only 1 scientific theory that is accepted as the origin of matter and that is the standard Big Bang theory that states that the universe was once very hot and very dense and expanded and cool from there. It doesn't state whether spacetime is infinite or finite, and both are possibilities that would fit just fine within the theory. If the universe is inifinite in size it is logical to think that there is an infinite amount of matter. If the universe is finite in size then the reverse is true and that there is only a finite amount of matter. Do we know that an infinite universe must contain an infinite amount of matter? No, but if it doesn't then we would have to rework some of our ideas. We simply don't know at the moment, but since the observable universe is seen to have lots of matter evenly distributed throughout it makes sense to think that the rest of the universe is the same way.

As for space being around forever, I can't comment on that, as anything I could say would be pure speculation. I have no idea if the universe came from "nothing" or not, or if there was really a singularity or not. I personally want to say that it makes no sense that we come from nothing, but the notion that the universe has existed in some form or fashion for an infinite amount of time is just as confusing and mind blowing as it coming from "nothing".

I think you misunderstand the scientific term "singularity" and are taking it to mean something specific physically. That's not what it means. What it MEANS is "the place where our models break down and we have no idea what was happening".

As Drakkith said, the big bang model says NOTHING about what what there at the "singularity" because the word just means "we don't know".

i did not clear picture about antimatter. is't only a little or much more than matter?

I'm sorry I can't understand you. Could you try to be a bit clearer with what you want to know?

Assuming that the mathematical theorems we discover or invent,
do reflect a "rich platonic world that is not of our making", what then?

Maybe the space-time of our world is funded somehow by a natural event
or an unholy failure in that robust Platonic world
(where anything which can happen does happen, and it happens all at once).

Space-time emerges in the absence of number, it begins where the numbers stop,
and our stars as well as ourselves are reassembling cannibalized bits of ruined integer meat,
and our world is as an after life of that that one,
and our doing mathematics, among other things, a form ancestor worship.
