According to Newtonian physics, the gravitational attraction between two masses is proportional to the inverse of the square ...

One question, for instance, might be why can't we walk through walls? Atoms, which are the building blocks of matter, are ...

"We were excited by recent discoveries that a process called magnetic reconnection heats ions 6.5 times as much as electrons," he says. "This appears to be a universal law, and it has been confirmed ...

Einstein’s theories contain calculations that lead to mind-bending predictions about the nature of space, time, and reality itself. These mathematical outcomes have redefined physics and challenged ...

Physicists have been puzzling over conflicting observational results pertaining to the accelerating expansion rate of our Universe—a major discovery recognized by the 2011 Nobel Prize in Physics. New ...

Physicists claim they may have found a long-awaited explanation for dark energy, the mysterious force that's driving the accelerated expansion of the universe, a new preprint study hints. Their ...
