A bundle of magnets and glass had a slight but detectable gravitational pull, pushing scientists closer to the boundary between classical and quantum physics. Reading time 3 minutes Despite keeping us ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

Add Yahoo as a preferred source to see more of our stories on Google. A illustration shows a quantum experiment investigating gravity on a tiny scale. Scientists have determined a way to measure ...

What is mass? It seems like a synonym for weight, but that isn’t quite right. Weight is how we measure the pressure that gravity exerts upon things. But mass? Mass is the actual presence of an item — ...

The weak gravitational pull on a particle just half the mass of a grain of sand has been measured for the first time. This most precise measurement of its kind is a breakthrough towards the quantum ...

Learn how to calculate the spin rate required for a spacecraft to generate artificial gravity at half of Earth’s gravity! In this video, we break down the physics behind rotational motion, centripetal ...

Just over a week ago, European physicists announced they had measured the strength of gravity on the smallest scale ever. In a clever tabletop experiment, researchers at Leiden University in the ...

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 ...
