The rapid expansion of the universe has been the most perplexing enigma in physics. To unravel this cosmic puzzle, scientists turn to the fundamental laws of physics, including Albert Einstein's ...

Spacetime itself would also need to be “quantized,” or broken down into constituent parts. This is what the notorious string theory attempts to do, as does loop quantum gravity, currently considered a ...

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 ...

In a landmark achievement, astronomers have noticed light bending in an unexpected manner, one that doesn’t align with the predictions made by Albert Einstein’s theory of general relativity. This ...

The geometry of spacetime forms the very foundation of modern gravitational theory, where the elegant interplay between curvature and matter is described by Einstein’s field equations. In this ...

In the 1900s, Albert Einstein unified the concepts of space and time, giving us a useful new way to picture the universe. At the start of the 20th century, physicists had a problem: The speed of light ...

A Google Deep Mind researcher and physics expert, Adam Brown, discusses what an AI Einstein would be like. Einstein coming up with General Relativity required coming up with new notation. Einstein’s ...
