General relativity helps explain the lack of planets around tight binary stars by driving orbital resonances that eject or destroy close-in worlds. This process naturally creates a “desert” of ...

New research suggests Einstein's general relativity explains the rarity of planets orbiting two suns. In tight binary systems ...

Relativity Space had been targeting Wednesday afternoon for the inaugural launch of Terran 1, the largest 3D-printed structure ever built. Reading time 4 minutes Update: 3:38 p.m. ET: Relativity Space ...

The team examined the remnant black hole’s “Kerr nature”, the mathematical description of a rotating black hole in general relativity. By analyzing the dominant quadrupolar mode and its overtone, they ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

As new and powerful telescopes gather fresh data about the universe, they reveal the limits of older theories like Einstein's relativity. When you purchase through links on our site, we may earn an ...

Relativity Space CEO Tim Ellis is hitting back against recent comments from fellow aerospace exec Peter Beck, who called launch contracts for un-flown rockets “basically worthless” earlier this month.

Einstein was awarded the 1921 Nobel Prize for a theory that half of the people might not even have heard of. His Theory of ...
