Physicists have measured the smallest gravitational field ever recorded, in an experiment that could help in the search for a unified theory of physics. Of the four fundamental forces known to physics ...

Traditionally, scientists have measured gravity’s influence on atoms by tracking how fast atoms tumble down tall chutes. Such experiments can help test Einstein’s theory of gravity and precisely ...

Gravity might feel strong if you drop a bowling ball on your feet, but is in fact the weakest force. Compare it to electromagnetism: the pull of all the Earth’s gravity can’t stop you from picking up ...

Sam Baron receives funding from the Australian Research Council. Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever ...
