The puzzle Einstein and Rosen were addressing was never about space travel, but about how quantum fields behave in curved spacetime. I ...
Physicists have demonstrated that waves can bounce off boundaries in time, not just in space, producing signals that behave ...
Theoretical research led by Professor Enrique Gaztañaga of the University of Portsmouth challenges the ...
Scientists using Google’s quantum processor have taken a major step toward unraveling the deepest mysteries of the universe. By simulating fundamental interactions described by gauge theories, the ...
Physicists are still puzzling over the true nature of dark matter and dark energy, because they have inexplicably added 10 times as much mass as normal matter has to the universe. Looking at the ...
