Weight is the force of gravity on your mass. Gravity close gravityThe force of attraction between all objects. The more mass an object has, the larger the force of gravity it exerts. is a force that ...

Phobos is the larger and closer of the two natural satellites of Mars. Despite decades of Martian exploration, we still know very little about Phobos. Many fundamental properties of this small ...

Scientists funded by the European Space Agency have measured the gravitational equivalent of a magnetic field for the first time in a laboratory. Under certain special conditions the effect is much ...

In order to allow for the experimental observation of gravitational bound states, all interactions of the matter particles with other fields must be so small that their interference with the ...
