The tiny bots follow patterns of light and "artificial space-time," navigating like craft following the curved space around a ...

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

Einstein's theory of general relativity views time similarly to width, height, and length. As such, both time and space can be curved by gravity. This effectively means that time is slower the closer ...

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

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 ...

Researchers report superluminous supernova SN 2024afav whose erratic behavior supports a long-standing theory of stellar ...

Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time and the latter a point in space, but in both cases the normally ...
