For over 100 years, two theories have shaped our understanding of the universe: quantum mechanics and Einstein’s general relativity. One explains the tiny world of particles; the other describes ...

The Big Bang is often described as the moment everything began — a point of infinite density where the laws of physics broke down. But what if that picture is incomplete? A new study proposes a ...

For over a century, physicists have grappled with one of the most profound questions in science: How do the rules of quantum mechanics, which govern the smallest particles, fit with the laws of ...

An optical lattice clock embedded in the curved spacetime formed by the earth’s gravity. Dynamical interplay between photon-mediated interactions and gravitational redshift can lead to entanglement ...

For over a century, physicists have grappled with one of the most profound questions in science: How do the rules of quantum mechanics, which govern the smallest particles, fit with the laws of ...

The theory of special relativity is rife with counterintuitive and surprising effects, the most famous of which are length contraction and time dilation. If an object travels at a relative speed, ...

In October 2015, a young mathematician named Clemens Sämann was flying home to Austria from a conference in Turin, Italy, when he had a chance encounter. He found himself seated beside Michael ...

Researchers have explored the interplay between gravitational effects and quantum interactions in optical atomic clocks, revealing more about quantum entanglement in precision timekeeping. For over a ...

For years, astronomers have wondered why real-life versions of Tatooine are so rare. With thousands of confirmed exoplanets and countless binary star systems in our galaxy, planets orbiting two suns ...
