It doesn't exist. So it doesn't come from anywhere.The universe began with nearly equal amounts of anti-matter and matter. No dark matter or dark energy required. Do you want me to explain it to you?I'm not gullible like you. Nor do I try to talk about things that have nothing whatsoever to do with the creation of the universe just to muddy the waters while denying the universe literally popped into existence 14 billion years ago and not be able to recognize that's what the big bang actually means.Unlike you I accept that every scientist says we cannot observe 95% of the universe and knowing that I have to say the Big bang while it is the best theory we can come up with might not be the whole picture.
So things that we know are part of the universe but don't understand weren't created when the rest of the universe was created?
And yet scientists cannot account for the movement of the universe without admitting there is more there than we can see.
So tell me where did the 95% of the universe that scientists know exists come from in not the same event that spawned the 5% of the universe we actually understand?
It's a measurement error of light across deep space. Acceleration hasn't changed.
