Astronaut Barry Wilmore is experiencing difficulties adapting to gravity after returning from a nine-month space mission. His ...

Scientists have long sought the particle that carries the force of gravity, but a new theoretical model tosses out that idea entirely – and shows how it could be tested in experiments ...

Developed in 1915, general relativity suggests that gravity arises because bodies with mass cause the fabric of spacetime (the four-dimensional unification of space and time) to warp. The greater ...

Two Mars gravity assists are expected, and NASA astronauts Suni Williams and Butch Wilmore are finally set to come home from an extended stay on the International Space Station. Here are five ...

But the European Space Agency (ESA) is looking at a far subtler approach to saving the planet – a gravity tractor. The plan involves sending a spacecraft to rendezvous with a dangerous asteroid ...

The Capillary Cup is a zero-gravity cup designed by NASA astronaut Donald Pettit on the International Space Station. The product is an open drinking cup designed to be used in a microgravity ...

Einstein’s general theory of relativity can be summed up in just 12 words: “Space-time tells matter how to move; matter tells space-time how to curve”. But this short description from the ...
