Time has always seemed like the one thing physics could count on. Matter changes, stars die, particles flicker in and out, ...

For over a century, scientists have accepted an uneasy truth. Quantum mechanics and relativity, two of the most successful theories in physics, don’t go along. This conflict becomes more apparent when ...

For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein's general relativity. One explains the tiny world of particles; the other describes ...

Diagrammatic representation of the entropic quantum gravity action. The action for gravity is given by the quantum relative entropy between the metric of the manifold and the metric induced by the ...

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. When you purchase through links on our ...

A team of physicists has proposed a specific modification to Einstein’s general relativity that could eliminate the Big Bang singularity, replacing it with a controlled high-energy phase governed by ...
