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 ...

Einstein’s theory of relativity has explained the universe for more than a century. But under certain conditions, cracks begin to appear. Physicists have identified a gap Einstein never had the tools ...

Planets that orbit white dwarf stars should be too hot to host alien life, theories suggest. But a new study accounting for Einstein's general relativity may rewrite that rule. When you purchase ...
