Anyone played Outer Wilds? (Highly, highly recommended, if not.) When I read this headline I thought, "My God, the Interloper's Ghost Matter came from us!" Of course (if you have any idea what I'm talking about) this is doesn't really fit. Or could it? Still, I thought it anyhow.

The Ice Cube neutrino detector is pretty impressive too, I guess.
