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 ...

Following the 3,000th orbit of NASA's AWE (Atmospheric Waves Experiment) aboard the International Space Station, researchers ...

Gravity, or gravitational attraction ... backward with respect to their normal orbits. This offended some astronomers' sense of cosmos, the orderliness of the universe. In a universe perfectly ...

Hollywood films would have us believe the best way to deal with an Earth-threatening asteroid is to blast it out of orbit. But the European Space Agency (ESA) is looking at a far subtler approach to ...

One application of the law of gravity is to figure out how to put a satellite into orbit so that it remains in the same position relative to ground all the time. A satellite in such a position can be ...

If gravity arises from entropy, scientists could unite Einstein's general relativity with the quantum realm while shedding light on dark matter and dark energy. A new recipe for gravity could help ...

Gravity also holds Earth and the other planets in their orbits around the Sun. The force of gravity also exists on the Moon but it is not as strong as it is on Earth. This is because the Moon is ...
