Yet again, scientists validated a major component of Einstein’s theory of general relativity, which has faced greater scrutiny from physicists. Specifically, a trio of two white dwarf stars and a...

A star orbiting the supermassive black hole at the center of the Milky Way has a bizarre orbit — but also one that strongly supports Einstein’s theories. After monitoring a star named S2 for 27...

A British theoretical physicist has developed a theory that could solve one of the universe’s biggest mysteries. That mystery is the universe’s rate of expansion, which is currently accelerating...

Astronomers have been puzzling over the mystery of dark energy, an unknown substance that makes up 70 percent of the known universe and seems to be intricately linked to its expansion. But a new...

For the first time, astronomers recorded the gravitational waves given off by the formation of a new black hole. The waves, which rippled out from the cosmic newborn like the sound waves emanating...

Einstein’s gravity-explaining theory of General Relativity may not tell the complete story of how galaxies and black holes formed throughout the universe. New supercomputer simulations implementing...

Crispy Black Hole It’s been exactly a month since the first photo ever taken of a black hole was released by am international coalition of scientists. The admittedly blurry image was taken by a...

Pale Orange Ring The image of a black hole shared by scientists on Wednesday represents many things. It’s the first-ever direct observation of a black hole’s event horizon, it’s evidence supporting...

Using data collected from their network of telescopes, the Event Horizons Telescope team hopes to produce the first ever image of a black hole in 2018.

Researchers from CalTech have published a paper supporting the idea that space-time and gravity emerge from quantum entanglement. This could help link the theories of general relativity and quantum...
