Planck data hint that gravity could weaken slightly on the universe’s largest scales, but stronger evidence is still needed.

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 ...

The largest survey ever conducted among physicists worldwide reveals surprisingly little agreement on some of the field’s ...

Scientists have spotted the first hints that Einstein's formulation of gravity operates in the quantum realm.

A quarter century ago, physicist Juan Maldacena proposed the AdS/CFT correspondence, an intriguing holographic connection between gravity in a three-dimensional universe and quantum physics on the ...

If we were living in a computer simulation, would we be able to tell we were living in a computer simulation? It's a question that's difficult to answer, but physicist Melvin Vopson of the University ...

What if gravity—the force that keeps us stuck to the planet—is actually just the universe trying to save processing power? According to physicist Melvin Vopson, this isn’t just the random musing of a ...

Scientists have used cutting-edge research in quantum computation and quantum technology to pioneer a radical new approach to determining how our Universe works at its most fundamental level. An ...
