Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...

Legend has it that Isaac Newton had the moment of inspiration that would lead to his theory of gravity when, on a warm afternoon, he saw an apple fall from a tree and wondered why it should fall down ...

If there's one thing everybody knows about space, it's that there's no gravity once you leave the Earth's atmosphere. We all know that don't we? It's actually not true — and an attempt at a massive ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

The idea of emergent gravity is still new and requires a lot of assumptions in its calculations to make it work. But if experimental evidence ever proves it real, we would need to totally rewrite the ...

Astronomers suggest that an alternative concept of gravity, known as modified Newtonian dynamics, could explain orbital inconsistencies that have previously pointed to the existence of a ninth planet ...
