Albert Einstein’s general theory of relativity does a great job at explaining gravity but it is thought to be incomplete ...

Earth’s spin is not as steady as it looks from the ground. As ice sheets melt and aquifers are drained, scientists now say ...

Earth's rotation is subtly accelerating, and scientists are intently tracking the trend. Usually, our planet takes 24 hours, or 86,400 seconds, to finish one complete spin. However, on July 9, 2025, ...

Quantum gravity remains one of the foremost challenges in theoretical physics, seeking to reconcile the principles of quantum mechanics with the geometric understanding of spacetime envisaged by ...

Levitating and spinning diamonds might sound like science fiction, but they’re now part of a bold effort to study the foundations of the universe. In a groundbreaking experiment, researchers have ...

Like you, I'm given to wondering about "what ifs" to better understand the assumptions we make about the world. One of my favorites is what if the Earth stopped rotating? Let's just say things would ...

We don’t often think about gravity, the invisible force that anchors us to Earth, as it always seems constant and dependable. However, it will slightly vary, sometimes by enough to make you weigh ...

NASA images show asteroid 2025 OW spinning at extreme speed, improving its orbit forecast and revealing surface details only ...

If you’re the kind of person who gets a lot done, you’re grateful for every one of the 86,400 seconds that make up a day. On July 9, however, as well as on July 22, and August 5, you won’t get your ...
