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

If true (and it’s a pretty big “if”), Vopson’s new gravitational study would shake the foundations of the currently accepted view of the universe. In his paper, Vopson writes that his new work could ...

For more than a century, gravity has been the stubborn outlier in physics, resisting every attempt to merge Einstein’s smooth ...

Unifying gravity and quantum theory remains a significant goal in modern physics. Despite the success in unifying all other fundamental interactions (electromagnetism, strong force and weak force) ...

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 ...

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 ...

We think of gravity as weighty—its omnipresent grasp pulling us down to the ground. Try to lift a piano up a flight of stairs and you can feel gravity’s resistance. ( Receive emails about upcoming ...

Time for a physics lesson. We only feel gravity’s effect on us when we fall but gravity is always working on us- pulling us down at a force equal to our mass times a constant of 32 feet per second ...

A magazine news story on the unification of physics usually begins by saying that Einstein’s general theory of relativity and quantum theory are irreconcilable. The one handles the force of gravity, ...
