To a certain floor. Of course a particle which only interacts gravitationally is still possible but that's the cosmologist's nightmare. It'd be basically impossible to prove it's existence and anything could happen (like a small but fast fairly massive ~asteroid mass clump of dark matter explaining poltergeists)
- ajross 2y ago> like a small but fast fairly massive ~asteroid mass clump of dark matter explaining poltergeists This is clever, but I have to believe the back of an envelope would show that a dark-matter scale distribution of "dark blobs" big enough to throw things around the room and frequent enough to be given names in human experience would be many, many orders of magnitude higher than the observed gravitational effects.
- throwawaymaths 2y ago> have to believe A lot of weird shit gets floated around, like planet X is dark matter, or at one point someone suggested sag x-1 was a dark matter blob. At that point Why not poltergeists?
