Oh no, it's not Make the Universe Great Again is it?

I'm a physicist so I'm honestly interested in the physics question of dark matter and don't care about
any rhetorical issues about ignorance.

That said - we have real evidence for at least some of dark matter. We have "seen" it indirectly from the gravitational effects in galactic clusters. I'll see if I can dig up a reference for this for you.

I mean maybe something is wrong with GR but if so, that still wouldn't explain some of the more specific evidence that we have of DM.

I am beyond skeptical re dark matter and dark energy, kind of like an omnipotent being you can't see, but is everywhere.

no its like light matter but much much darker

Thinking of protons nutrons and electrons in an atom would have to thin the same in space matter antimatter dark matter.
