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 ...

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 ...

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

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 ...

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 ...
