When I was five years old, my family moved into a 1930s semi-detached house with a long strip of garden. At the end of the garden was a miniature orchard of eight apple trees the previous owners had ...

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 ...

For decades, quantum physics and general relativity have stood as two powerful but separate theories. Quantum physics explains the behavior of tiny particles like atoms and photons. General relativity ...

Albert Einstein's theory of general relativity—which explains gravity as the product of the distortion of space and time—may not be universally applicable. This is the conclusion of physicists from ...

Exploring the BTZ black hole in (2+1)-dimensional gravity took me down a fascinating rabbit hole, connecting ideas I never expected—like black holes and topological phases in quantum matter! When I ...

One way to longer life may be higher gravity—at least for rats. That is the “very tentative suggestion” of experiments performed by NASA Physiologist Jiro Oyama, who has been raising mice and rats ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...
