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 ...
Scientists hope to probe the nature of general relativity through a possible pulsar found in the center of the Milky Way, near a supermassive black hole.
Einstein’s theory of relativity has explained the universe for more than a century. But under certain conditions, cracks ...
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 ...
