This new propulsion system could rewrite the rules of spaceflight—not to mention completely defy conventional physics.

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy.

At the age of 23, young Isaac Newton realizes that gravitational force accounts for falling bodies on earth as well as the motion of the moon and the planets in orbit. This is a revolutionary step ...

What did Newton understand that was such a revolution? Can someone just... explain gravity to me? Let's start with a ...

Isaac Newton changed the way we understand the Universe. Revered in his own lifetime, he discovered the laws of gravity and motion and invented calculus. He helped to shape our rational world view.

In a new Physical Review Letters study, researchers propose an experimental approach that could finally determine whether gravity is fundamentally classical or quantum in nature. The nature of ...

Sir Isaac Newton wrote his theory of gravity in a home-made ink created with beer as a key ingredient, a study suggests. The physicist published his theory of calculus, his three eponymous laws of ...

New Scientist once described Isaac Newton as “the supreme genius and most enigmatic character in the history of science.” His three greatest discoveries — the theory of universal gravitation ...

TIM PEAKE:Hi, I'm Tim Peake. I'm an astronaut based here at the European Space Agency, in Germany. And from December 2015 to June 2016, I spent six months orbiting Earth on the International Space ...
