Clarify one of physics’ most fundamental concepts with “g”: Gravity vs. Gravitational Field explained! 🌍 In this video, we break down the difference between gravitational acceleration and the ...

In quantum mechanics, charged particles like electrons can be sensitive to the effects of electromagnetic fields, even when placed in a region where both the electric and the magnetic fields are zero.

Over the Christmas season of 2019, four physicists hovered over two minuscule gold orbs, each about the size of a ladybug, in a Vienna laboratory. It was silent, in all the ways you can imagine: ...

On January 14, 2025, a pair of black holes with nearly identical masses crashed together roughly 1.2 billion light-years away, producing a gravitational wave signal so clean and powerful that it ...

Gravity is a ubiquitous part of our daily lives — whether we’re being tragically brought to our knees after tripping on the rug or gleefully jumping from a swing’s apex. But despite how common the ...

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 ...

Black holes may defy the famous “no-hair” theorem by leaking residual gravitational ripples that could one day be observed by gravitational-wave detectors. Such an observation would provide evidence ...

New research has shown that future gravitational wave detections from space will be capable of finding new fundamental fields and potentially shed new light on unexplained aspects of the Universe. New ...

In 1797 Henry Cavendish, one of Great Britain’s leading scientists, built a contraption to weigh the world. At the time, Earth’s mass was unknown, as was its composition. Was it mostly solid rock? Did ...

The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. The gravitational pull between two objects can be ...
