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 ...

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 ...

While quantum mechanics governs the behavior of particles at the smallest scales, general relativity describes the force of gravity on cosmic scales. Unifying these two frameworks has been one of the ...

A biochemist breaks down challenges that astronauts Suni Williams and Butch Wilmore will face after their long duration in ...

Scientists have long sought the particle that carries the force of gravity, but a new theoretical model tosses out that idea entirely – and shows how it could be tested in experiments ...

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 ...

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 ...

Neutrinos may be the key to quantum gravity, potentially leading to a unified theory combining quantum mechanics and general relativity.

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 ...

While quantum mechanics governs the behavior of particles at the smallest scales, general relativity describes the force of gravity on cosmic scales. Unifying these two frameworks has been one of ...
