Gravity is the force of attraction between two objects. Its effects play an interesting role between a giant planet such as Jupiter or Saturn and their numerous moons — for instance, the Galilean ...

A new study has revealed that gravity's effect on Earth is constantly shaping the surface of our planet. When our planet formed, it did so by pulling dust and rock toward its gravitational field. As ...

Although gravity seems strong in our everyday lives, such as when lifting a heavy object, it is the weakest of the four fundamental forces. The gravitational force between two bodies is proportional ...

Gravity behaves predictably in your daily life. Drop a ball, and it falls. Planets loop around stars. On paper, the same rules should also govern matter spread across the universe. But the farther ...

If gravity is the weakest of the four fundamental forces, how can the Sun’s gravity affect distant and low-mass objects such as those in the Kuiper Belt and Oort Cloud? It is true that gravity is ...

For decades, physicists searched in vain for evidence of gravitational waves, the stretches and squeezes in spacetime that were first predicted by Albert Einstein’s theory of general relativity a ...

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, ...

Researchers have redetermined the gravitational constant G using a new measurement technique. Although there is still a large degree of uncertainty regarding this value, the new method offers great ...

In February 2016, an international team of physicists announced the first direct observation of gravitational waves. The waves had been produced by the gigantic collision of a pair of black holes, ...

One of the things we often just accept about the world is that physical effects get weaker the farther away we get from them. Light sources appear dimmer, the gravitational force gets weaker, magnets ...
