The new data provide the clearest evidence yet for long-held fundamental predictions by Albert Einstein and Stephen Hawking.

The discovery that black hole growth may not be limited to galactic centers could shed light on the role supermassive black holes, with masses millions or billions of times that of the sun, play in the evolution of their host galaxies, as well as indicating how these cosmic titans grew so large so rapidly in the early universe.

Scientists ultimately settled on a feeding black hole at the heart of a far-distant galaxy as the most likely engine for 3C 273’s ridiculous luminosity. In fact, by the 1980s astronomers were starting to suspect that every big galaxy had a supermassive black hole in its center.

Spacetime ripples from a black hole collision across the cosmos have confirmed weird aspects of black hole physics

The merger of two black holes is a momentous event, revealing the wildest and most extreme configurations of space, time and gravity known to science.

The most exciting yet controversial possibility traces back to a theory proposed by British physicist Stephen Hawking in 1971: that black holes originated from the primordial soup of the Big Bang. If this is the case, then this celestial body has existed in darkness since the universe's inception, waiting for stars and galaxies to illuminate it.

This week, researchers reported on a new biopsy tool that can detect HPV-associated head and neck cancer up to 10 years before symptoms appear. Researchers developed a process to transform two-dimensional paintings into full-color,
