It’s time we talked about loop quantum gravity. What exactly is it? What are the loops? And can it really defeat string theory in our quest for a Theory of Everything? PBS Space Time is available to ...

Of the four fundamental forces of physics, gravity is the one we’re most familiar with in everyday life, but it’s also the only one that can’t currently be explained by quantum physics. Now scientists ...

For decades, physicists have struggled to reconcile the laws governing the very small with those that describe the vast cosmos. Quantum mechanics rules subatomic particles, while general relativity ...

Cooling metal bars to near absolute zero, suspending microscopic gold beads, or searching for signs that gravity might be quantum: meet the scientists hunting for gravity's elusive nature ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

For a long time, scientists knew of a “gravity hole” beneath Antarctica—an area with particularly weak gravitational force. Considering the various threats currently faced by the region, scientists ...

The accelerating expansion of the universe could be explained by modifying general relativity so that gravity has mass – or so thinks a small group of physicists. Matthew Francis reports What lies ...

Isaac Newton was an English polymath who worked in many areas, such as math, physics, astronomy, alchemy, theology, writing, and inventing. His work c.
