There’s a new generation of experiments that may unlock the gravity particle. Physicists have long believed that detecting the particle of gravity—the graviton—was fundamentally impossible, with the ...
Light from a distant galaxy becomes warped as it travels through space-time gravitationally curving around a foreground ...
(via PBS Space Time) Physics is this close to understanding the entire universe. And what lives in this gap? Many physicists think it’s the elusive graviton—the quantum particle of gravity—whose ...
Ghostly particles could be haunting our universe. A new theory claims that the cosmos is full of unseen particle families that don’t interact with each other. If true, the model could explain why ...
A new theory suggests that gravity could possibly be the result of entropy. If true, this would mean that everything in the universe would fall apart if it all remained unchanged. This theory tries to ...
Newton’s Law of Gravity just survived its biggest cosmic test. Scientists studied nearly 686,000 galaxies spread across 7 ...
Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works extremely well in its own domain: Quantum theory explains how atoms and ...
Black holes have a problem that physicists still cannot explain. According to Stephen Hawking’s ...
