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 ...

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 ...

It might not be obvious to those of us only grappling with more mundane concerns, but for cosmologists bent on unlocking the universe’s deepest secrets, there’s no shortage of problems keeping ...

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 ...
