Physicists should rethink interference experiments to reveal whether or not general relativity follows classical theory, argue Chiara Marletto and Vlatko Vedral. Sixty years ago, physicists ...

AN absolute determination of the acceleration due to gravity at a site in the National Physical Laboratory has recently been completed. It is the first to be made by timing the symmetrical up-and-down ...

In 1797 Henry Cavendish, one of Great Britain’s leading scientists, built a contraption to weigh the world. At the time, Earth’s mass was unknown, as was its composition. Was it mostly solid rock? Did ...

Today, Zero Gravity Corporation (ZERO-G) announced the establishment of the ZERO-G WEIGHTLESS LAB. The specially designed two-day program provides the only commercial access to Martian, Lunar, zero ...

It’s possible to study how gravity affects small objects here on Earth, but most alternatives to general relativity predict that there will be differences between gravity’s influence on small and ...

Albert Einstein may have been right that gravity travels at the same speed as light but, contrary to a claim made earlier this year, the theory has not yet been proven. A scientist at Lawrence ...
