Dark Matter and the Universe

In the very early universe, there was so much energy in all the quandum fields that, like, particles aren't even really a reasonable thing to talk about. But then as things cooled, right, and things got more dilute, and as the big bang, went on. Then there was a moment when these particles sort of like became the way to think about the universe. D this is how we think about it. If we met aliens, they would be very confused by our description of the universe. We're trying to find the right language to use to describe the universe. None of this is fundamentally true.
