More like antigravity galaxies? Inflation theory explained by + and - galaxies repulsing each other while behaving "normally" in their local environment.

Me: Alright, what weirdo wrote this?
Oh.
He's the reason that "Harvard astronomer" is very close to being used as a derogative.

I knew who this article was by just from your intro.
When Kip Thorne lectures about the "wormhole" concept in Interstellar, it requires negative mass to hold the wormhole open.
So if there isn't any, no wormholes. Sorry.
The Robert Forward novel "Timemaster" explores the concept by having somebody encounter beings made of negative matter, who can be talked into holding wormholes open, no less.
Forward notes that negative matter brought into contact with positive, would not blow up, but just vanish - negative mass cancels positive.
