RE: How the recently observed light from the Cosmic Dawn impacts dark matter

Thanks for sharing @lemouth!

At the same moment of the universe history, dark matter is at its coldest phase as well. It may thus cool down the hydrogen gas, which could then induce a larger absorption in the spectrum.

Does that basically mean that scientists are absolutely aware of the way ordinary matter interacts with dark matter and vice versa? After learning from a previous post of yours how dark matter is actually not electromagnetically interacting, I was wondering whether there could be any sort of differences regarding transmission of heat between ordinary and dark matter.

p.s. : I'd love to read a post of yours regarding the quantum entanglement theory and discuss whether this reality could actually be a computer simulation.

Nice read!

There are indeed a few assumptions in there. A small number of reasonable assumptions yields realistic models, like the one described here.

This occurs through elastic scattering. One dark particles meets one normal particle and exchange energy in one way or the other (but not electromagnetically).

I could try, but this is far fro my area of expertise. I could write a few things about quantum entanglement, but this will stay at the level of generalities. Sorry :)

Thanks for taking the time to respond! :)

I always do that :)

And I always say thanks :P
