According to science, time travel is based on Einstein’s theory of special relativity, which he published in 1905. The German ...

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 ...

"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 ...

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.

In a study published March 11 in the scientific journal Physical Review Letters, two researchers applied quantum mechanics to a theoretical model of a black hole. Their results suggest a possible ...

Cosmic speed limits can be a major inconvenience but they've rarely stopped science fiction in its tracks.

In the 53 years since Albert Einstein published his general theory of relativity, it has withstood determined attacks and ingenious experiments by other scientists anxious to test its validity.
