Einstein’s theory of gravity may behave slightly differently across distances of billions of light-years, with gravity ...

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 ...

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 ...

IN MARCH, a team of physicists announced that they had detected ripples in space-time produced at the universe’s birth. Their claims took the world by storm. One of my colleagues declared it the most ...

After Albert Einstein published his special theory of relativity in 1905, he spent the next decade trying to come up with a theory of gravity. But for years, he kept running up against a problem. He ...

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 ...

As researchers detail in a study published today in the journal Nature, a star dubbed S301 exists so close to Sagittarius A*, ...

Standing on the sandy, windswept shores of Provincetown, Massachusetts, people may find themselves squinting at the horizon, ...

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 ...
