"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 ...

We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

The new findings come from the Dark Energy Spectroscopic Instrument (DESI), which sits on a telescope at the Kitt Peak ...

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

Dark energy, the mysterious force thought to be driving the ever-faster expansion of the universe, appears to be changing ...

Physics has a problem—their key models of quantum theory and the theory of relativity do not fit together. Now, Dr. Wolfgang Wieland from Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU ...

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...

Elusive black hole radiation predicted by Stephen Hawking may have influenced the way the universe took shape after the Big ...

In a study published March 11 in the scientific journal Physical Review Letters, two researchers applied quantum mechanics to ...

Physicists may need to come up with a new theory for how the universe works, after a dark energy experiment has produced ...

Before it shut down, a telescope in Chile captured the universe's baby photos, just 380,000 years after the Big Bang. These ...
