From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this familiar force remains one of the biggest puzzles in physics.

As far as physicists have been able to determine, nature speaks two mutually unintelligible languages: one for gravity and one for everything else. Curves in the fabric of space-time tell planets and ...

Physics can be pretty intense at times, but one of the most straightforward aspects is that everything in the Universe is controlled by just four fundamental forces: gravity, electromagnetic, and ...

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 ...

Of the four known fundamental forces of nature, the weak nuclear force is the one with the least obvious purpose. Gravity ...

Gravity is the force of action between two objects. It’s called a natural force because it acts at a distance rather than needing to be in contact. Gravity is the force that holds us down on Earth and ...

New research conducted by nuclear physicists is using a method that connects theories of gravitation to interactions among the smallest particles of matter. The result is insight into the strong force ...

Electromagnetic momentum and optical forces have emerged as pivotal concepts in modern optical science, bridging fundamental physics and advanced technological applications. At its core, ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. A proton isn't just three quarks and gluons, but a sea of dense ...

The Watt Balance is one of the most precise instruments ever created - a device that measures mass using electromagnetic ...
