I see these new images as the start of a more demanding exam for general relativity, one that will compare theory and observation feature by feature instead of relying on broad agreement. The closer ...

When gravity—an invisible yet ubiquitous force—bends and distorts light from distant galaxies, Earthbound observers get a rare glimpse of elusive cosmic phenomena. And the weirder the glitch, the more ...

A black hole can feel like the most distant and unreal object you could ever think about, yet the way its darkness bends light may one day speak directly to the deepest parts of physics. If you have ...

New research suggests future images of black holes could be precise enough to allow scientists to determine if these objects are accurately described by Albert Einstein's theory of gravity, general ...
