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 ...

Einstein’s central coup with general relativity was to combine that with a principle noted over three centuries earlier by Galileo: that falling objects accelerated at the same rate regardless ...

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

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.

For decades, physicists have struggled to reconcile the principles of quantum mechanics with those of general relativity.

Let's first look at one of the most famous tenets of General Relativity—the Equivalence Principle. The Equivalence Principle states that gravity and acceleration are the same. It is at the core ...

On 25 November 1915, Albert Einstein presented his general theory of relativity at the Prussian Academy of Sciences. This theory is still considered to be the most important idea in modern physics.

For decades, physicists have struggled to reconcile the principles of quantum mechanics with those of general relativity. While quantum mechanics governs the behaviour of particles at the smallest ...
