A new discovery suggests gravitational fields can enable matter to become quantum entangled — and that's even if the concept of quantum gravity does not exist. The idea comes from two London-based ...

Measuring the strength of gravity is extraordinarily difficult, and different experiments have always disagreed – but a new ...

After a 10-year effort, physicists got a value for “Big G” that does not settle the debate over one of nature’s hardest numbers to nail down.

To live on the moon or Mars, humans will need heat and air conditioning that can operate long term in reduced gravity and temperatures hundreds of degrees above or below what we experience on Earth.

From egg drops to marble runs, gravity experiments turn abstract science into exciting play. These hands-on activities spark curiosity while teaching core physics concepts. Perfect for classrooms or ...

Let’s talk about quantum gravity experiments that can be done here on Earth! If we discover how to connect quantum mechanics with general relativity we’ll pretty much win physics. There are multiple ...

The concept of spacetime, first described in Einstein's theory of general relativity, has since been widely studied by many ...

GALVESTON, Texas — When the Apollo 11 crew got back from the moon 40 years ago this week, they showed no ill effects from seven days spent in weightlessness. But as American astronauts and Soviet ...

These specialized flights allow scientists to simulate weightlessness, providing a unique environment to study physical and ...

There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...
