A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

For 90 years, physicists have tried to solve the equations that constitute Albert Einstein’s theory of general relativity — the concept that matter, space and time are intertwined. But some of ...

Quote of the day by Newton: 1915 changed physics forever. In that year, Albert Einstein published the general theory of relativity and reshaped our understanding of gravity and spacetime. For 228 ...

Physicists have long struggled to unite quantum mechanics—the theory governing tiny particles—with Einstein’s theory of ...

The fabric of space and time is not exempt from the effects of gravity. Plop in a mass and space-time curves around it, not dissimilar to what happens when you put a bowling ball on a trampoline. This ...

The Einstein equations remain the cornerstone of general relativity, underpinning our understanding of how matter and energy influence spacetime curvature. Recent investigations have not only ...

Rochester Institute of Technology professors have developed a faster, more accurate way to assess gravitational wave signals and infer the astronomical sources that made them. Their method directly ...

Add Yahoo as a preferred source to see more of our stories on Google. Solutions to Einstein's famous equations back in the 20th century describe 'wormholes,' or tunnels through space-time. Mark ...

Oftentimes, we think of space as an endless, mostly empty vacuum, a silent backdrop where planets, stars, and galaxies play out their dance. We also think of time as something separate, a steady ...
