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 ...

Black holes are points in space that are so dense they create deep gravity sinks. Beyond a certain region, not even light can ...

Physicists have introduced quadratic quantum gravity (QQG), a theoretical extension of Einstein’s general relativity, that could eliminate the Big Bang singularity. This model envisions the universe ...
