Negative Mass: When Physics Runs Backwards
What if there was such a thing as negative mass? That would be quite a weird phenomenon, gravity would be repulsive rather than attractive and objects wouldn’t move like we expect them to. And whilst we’ve never observed such a strange thing happening, the physics certainly doesn’t ban it. Well then let’s find out more.
