🕑 Added 2021-11-24 15:27:48 +0000 UTCI got into physics by reading science fiction and one of the technologies that has always fascinated me most was -- no, not the transporter -- but anti-gravitational devices. Imaging jumping off a rooftop and just flying away. Why do we have repulsive electric forces but not repulsive gravitational forces? On Saturday I tell you how much we know about anti-gravity, and also why it doesn't explain dark energy.
