Physicists propose a relativity tweak that could remove the Big Bang singularity
Three physicists have proposed a modification to Einstein’s general relativity that, if confirmed, could eliminate the singularity at the origin of the universe. By adding higher-curvature terms to ...
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 ...
Space–time collision Artist’s impression of a black-hole binary system generating gravitational waves. The black holes will eventually merge, and this latest research could improve our understanding ...
In Newtonian physics, space and time had their independent identities, and nobody ever got them mixed up. It was with the theory of relativity, put together in the early 20th century, that talking ...
