Default Dark Matter might be an Illusion

Dark Matter Is an Illusion, New Antigravity Theory Says

I won't speak about the legitimacy but it's certainly interesting.

Interesting. It seems antimatter may be more common in the universe than previously thought.

Gravitation is still an unknown factor as to how it truly works, so no wonder the theory is based around that. Add the oddities of quantum mechanics on top of that and it all becomes even more uncertain.

Antimatter having negative gravitational charge would mean one of two things:
1) Inertial mass (i.e. the m of F=ma) is not the same as gravitational mass.
2) you can build perpetual motion machines.

The former breaks relativity, which is quite unfortunate, but the second breaks thermodynamics, which is even worse.

In terms of more basic physics, remember Galileo dropping stuff from the Leaning Tower of Pisa? That doesn't work anymore. If the article's right, then an antimatter ball would either fall down at a different speed from a normal-matter one, or it would fall up.

I saw the word Pandora cluster and wanted to say that it's probably just the flux vortex giving that cluster the weird results.

It seems like everybody is moving forward. As if there is some final goal they can achieve and get to. I don't get it though. When I look around, it seems like I'm already there, and there is nothing left to do.

I wish I could take just one hour of what I experience out in nature, wrap it in a box, put a bow on it, and start handing out to people
