A pulsar’s gentle twinkle is revealing how space quietly bends and delays the signals we receive from the cosmos.

Physicists have recently uncovered a groundbreaking material known as “time crystals,” which challenges our conventional understanding of time and space. This discovery, rooted in quantum physics, ...

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 ...

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 ...
