As a theoretical physicist based in Cambridge, I have lived my life in an extraordinarily privileged bubble. Cambridge is an unusual town, centred around one of the world’s great universities. Within that town, the scientific […]

Tying loose ends? Gravitational waves could solve string theory, study claims

New paper suggests that the hotly contested physics thesis, which involves the existence of six extra dimensions, may be settled by cutting-edge laser detectors. String theory makes the grand promise of weaving together all of physics into a single sublime framework. The only downside is that scientists have yet to find any experimental proof that […]

A real one just finished its first test flight program, as the Aurora Flight Science LightningStrike XV-24A Demonstrator Craft ended its first stage of flight […]
