Anti-particles also have a different spin (I think), due to certain factors that are beyond my comprehension.

Anti-particles have the same spin, but opposite charge. I'm not sure what all the details are about spin. It's a rather confusing subjuect to me at times. This helps a bit though.

I think Baryons, which are made up of 3 quarks have odd spins like 1/2 or 3/2 and so on. They make up normal matter like protons and neutrons.
Mesons have 2 quarks and have even spin like 0 or 1. Some mesons can be their own anti-particle. Here is a quick site.

Mesons also don't obey the "Pauli exclusion principle" which I think mostly says 2 particles can't occupy the same state. Thats part of what keeps electrons, which are Baryons, separated in their electron configurations. Here's more on that

I think I read somewhere that mesons, since they don't obey the Pauli exclusion principle, don't interact with most matter, and were hard to detect because of this. If dark matter is made up of these particles then it would be hard to find.
Black holes, now thats a whole other suject...
Anyway, I'm sure there is more I didn't say but my fingers are getting sore from typing for now. Hope some of you find this interesting.
