"The singularity is the most mysterious and problematic part of a black hole. It's where our concepts of space and time ...

Recent research suggests wormholes may already have been detected. Could Einstein have been right all along? How these ...

Dark matter, dark energy, the Hubble tension: underpinning these theories is Einstein’s general theory of relativity, which treats space and time as a unified “spacetime” and considers ...

Looks like we’re closer than ever to connecting general relativity and quantum mechanics. A new study suggests that when we ...

Studying these signals could not only confirm Einstein's prediction but also shed light on some ... massive objects warping space-time can generate ripples that travel across the universe at the speed ...

By modifying Einstein's theory of general relativity, the center of a black hole with infinite curvature could be replaced by a highly curved but regular region of space-time, the researchers suggest ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding ...

From 2035, the Einstein Telescope will be able to study gravitational waves with unprecedented accuracy. For the telescope, ...

Einstein's theory of general relativity suggests that the "memory" of ancient events, such as black hole mergers, may be etched into the fabric of space-time by gravitational waves. New research ...

By modifying Einstein's theory of general relativity, the center of a black hole with infinite curvature could be replaced by a highly curved but regular region of space-time, the researchers ...
