started rising. As the ground rebounded in this fashion, the gravity field changed. “The Earth behaved much like putting your finger into a sponge ball and watching it slowly bounce back,” said ...

An engineer who once worked with NASA says he has built a machine that can push against gravity without burning a drop of ...

This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

In 2023, astronomers detected a huge collision. Two unprecedentedly massive black holes had crashed an estimated 7 billion light-years away. The enormous masses and extreme spins of the black holes ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...

Gravity is usually presented as the most familiar of nature’s forces, the quiet background pull that keeps feet on sidewalks ...

Dr Charles Buhler takes people through his lab in a new video. He explains more about how they developed and detected a new force from large electrostatic pressure differences. They claim this force ...

The power of gravity is writ large across our visible universe. It can be seen in the lock step of moons as they circle planets; in wandering comets pulled off-course by massive stars; and in the ...
