Two experimental methods are described for measuring the gravitational force on electrons falling through vertical metal tubes. A third method is being devised to study the fall of positrons. You ...
Now, a team of physicists from the Netherlands and Germany claim they have devised the very experiments that could reveal whether gravity is fundamentally a quantum force, its properties shaped at ...
Narrator: Leonardo understood that gravity caused falling objects to accelerate. Seeking to measure this force, he designed an experiment. He filled a jar with sand and then emptied it while ...
