Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Astronomers have seen spacetime itself wobble near a spinning black hole for the first time. The discovery, revealed during a star’s destruction, confirms a major prediction of Einstein’s theory of ...

Scientists could soon test Einstein's theory of general relativity by measuring the distortion of time. General relativity states that gravity is the result of mass warping the fabric of space and ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

The universe’s accelerating expansion has long puzzled physicists. For decades, dark energy, an unseen force thought to make ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

For over a century, scientists have been intrigued to decode the perplexing scenery behind contemporary physics. It's been up for many years, and yet the experts still have no idea how to bridge the ...

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 ...

Although quantum mechanics and general relatively help explain the universe—at both small and cosmic scales—the two theories are fundamentally incompatible with each other. This has spawn theories ...

A violent stellar disruption recorded in 2024 has given astronomers their most comprehensive evidence yet of a black hole twisting the very fabric of spacetime around itself. This effect is known as ...
