From Newton’s falling apple to Einstein’s curved spacetime, our understanding of gravity has come a long way, yet this ...

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 ...

Physicists have measured the smallest gravitational field ever recorded, in an experiment that could help in the search for a unified theory of physics. Of the four fundamental forces known to physics ...

Robert Monjo, Ph.D., mathematics professor at Saint Louis University-Madrid, has introduced a theory that may transform scientists' understanding of gravity and its relationship to quantum physics.

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 ...

For over 50 years, physicists have generally agreed that the interactions between elementary particles are governed by four fundamental forces: the strong force, weak force, electromagnetic force and ...

Dark matter makes up 27 percent of the universe’s total mass and energy — nearly five times more than “normal” matter that comprises planets and stars. True to its name, dark matter is hard to ...

In a groundbreaking discovery, researchers have detected a previously unknown quantum force capable of bending light in controlled lab simulations. This finding challenges our current understanding of ...

Quantum gravity tries to combine Einstein’s general theory of relativity with quantum mechanics. Quantum corrections to classical gravity are visualized as loop diagrams, as the one shown here in ...

Have you ever stood by the sea and been overwhelmed by its vastness, by how quickly it could roll in and swallow you? Evidence suggests that we are suspended in a cosmic sea of dark matter, a ...

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 ...
