When you travel through the Universe, it isn't just a free ride through empty space. Although you might not think about it very often, there are forces arising from the presence of everything else, ...

European scientists are turning an aircraft into a laboratory that simulates lunar gravity to prepare astronauts and ...

With his theory of General Relativity in 1915, Albert Einstein revolutionized how we think about our universe. Rather than the cosmos simply providing the room for the planets and stars to orbit each ...

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where ...

Four fundamental forces are known in physics: the weak and strong interactions, and the electromagnetic and gravitational forces. The gravitational force is the weakest of these four. For this reason, ...

Researchers have succeeded in measuring the gravitational field of a gold sphere, just 2 mm in diameter, using a highly sensitive pendulum - and thus the smallest gravitational force. The experiment ...

Picture this: You’re floating in deep space, and there's a cute little beach-ball-size asteroid just 3 meters away. The rock’s mass is twice that of yours. You want to get to that asteroid, but you ...

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 ...

The gravitational force is by far the weakest of the four forces of nature. It’s simple to defy gravity: just lift something in the air. But the annoying thing about gravity is that it’s both ...

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 ...
