Space-based experiments show fungi can efficiently extract valuable metals from meteorites in microgravity, advancing prospects for asteroid biomining and sustainable resource use. As humans look ...

Pushed down to a certain scale, the laws of physics seem to fall apart. Astrid Eichhorn, a leader in an area of study called asymptotic safety, thinks we just need to push a little further.

While many of the experiments it will conduct in the coming months are classified, the Space Force has identified space-based laser communications and quantum sensing as two of its focus areas.

What does it mean to be to space-time? The seemingly simple question gets to the essence of twentieth-century physics and has driven a hundred-year debate between philosophy and science. In Einstein’s ...

Whether space-time exists should neither be controversial nor even conceptually challenging, given the definitions of “space-time,” “events” and “instants.” The idea that space-time exists is no more ...
