Weight is the force acting on an object due to gravity - it has the unit newtons (N) and acts towards the centre of a gravitational field. So weight is a gravitational force on an object that has mass ...

New antigravity solution will enable space travel near speed of light by the end of this century, he predicts. On Tuesday, Feb. 14, noted physicist Dr. Franklin Felber will present his new exact ...

Proceedings of the National Academy of Sciences of the United States of America, Vol. 113, No. 42 (October 18, 2016), pp. 11662-11666 (5 pages) A conserved stress energy tensor for weak field ...

There’s a new entrant in the competition to develop ever-tinier instruments that can detect changes in our planet’s gravitational field — a tabletop device roughly the size of two smartphone stacked ...

The answer depends on your location, your distance from the centre of Earth and any local variation in gravitational field strength due to the density of underlying rock. Crunching the numbers, the ...

Four fundamental forces are known in physics: the weak and strong interactions, and the electromagnetic and gravitational forces. The gravitational force is the weakest of these four. For this reason, ...

Ancient pieces of continental crust that are falling to the bottom of the Earth’s mantle could explain mysterious dents in our planet’s gravitational field. Sail towards the centre of the Indian Ocean ...

If you’re superstitious, a black cat in your path is bad luck, even if you keep your distance. Likewise, in quantum physics, particles can feel the influence of magnetic fields that they never come ...
