Gravity is supposed to be the most familiar force in nature, yet at the deepest level it remains the least understood. A bold ...

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 ...

A unified Theory Of Everything is the holy grail of physics, but gravity refuses to play ball. A newly proposed theory attempts to unify Einstein’s theory of gravity with quantum mechanics – and ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

A long-standing challenge in physics has been to integrate gravity into the Standard Model, which successfully describes the electromagnetic, weak, and strong forces. The difficulty lies in the ...

Global climate models capture many of the processes that shape Earth's weather and climate. Based on physics, chemistry, ...

Physicists in the US have used a tabletop experiment to rule out the existence of strong, gravitational-like forces at short length scales. Such forces, which could hint at additional space–time ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of ...

Now if the scientific community came along and said dark energy was a force, and said it has more in common with gravity that the other forces, that would sit right with me. It would be like those 2 ...
