We have long taken it for granted that gravity is one of the basic forces of nature—one of the invisible threads that keeps the universe stitched together. But suppose that this is not true. Suppose ...

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 ...

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 ...

Every time a coffee mug drops, a satellite orbits or an astronaut floats, we are watching the same phenomenon play out under very different disguises. For centuries we have treated gravity as the ...

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 original version of this story appeared in Quanta Magazine. Two blind spots torture physicists: the birth of the universe and the center of a black hole. The former may feel like a moment in time ...

Scientists have discovered that dark matter, the universe's most mysterious "stuff," obeys gravity on vast cosmological scales. This could help to dismiss the possibility of a fifth fundamental force ...

WHEN the two most important figures in your life don’t get along, there will always be trouble. Just ask physicists: the two most totemic theories in their field are fundamentally incompatible, and ...

Melvin M. Vopson is affiliated with the University of Portsmouth and the Information Physics Institute. We have long taken it for granted that gravity is one of the basic forces of nature – one of the ...
