The space telescope's image of a odd-looking spiral galaxy is, in reality, two distant galaxies overlapping each other.

The strange sight is actually two galaxies, with the light of the second warped around the one at the front as a result of ...

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

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 ...

Black hole singularities should not exist, according to theories of quantum mechanics. New tweaks to Einstein's equations of general relativity could finally do away with them, and explain what truly ...

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 ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy.

From 2035, the Einstein Telescope will be able to study gravitational waves with unprecedented accuracy. For the telescope, researchers from Jena have manufactured highly sensitive sensors made ...

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 ...
