We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

Gravity is the most familiar of nature’s forces. It keeps our feet planted on the ground and dictates the movements of ...

How does gravity work? Gravity applies an effective force of mutual attraction to things with inertial mass, including ...

Great! So, what's gravity? Aaaah, gravity is the force that makes objects fall towards the ground. And, without gravity, we'd all float! Hmmmm… You're right! The force of gravity is weaker on ...

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether ...

The ideal solution, it’s been argued, is to design future spacecraft with the ability to impart some degree of artificial gravity on its passengers through centripetal force. The technique is ...

Back in 1687, Sir Isaac Newton realised that the size of the force of gravity depends on two things: the mass of the two objects and the distance between the two objects. He found that ...

Gravity could feel like a punishing force as Sunita Williams and Butch Wilmore’s bodies readapt to life on earth. Stranded astronauts Sunita Williams and Butch Wilmore are expected to return to ...
