Since the third Gaia data release in 2022, wide binary stars with separation greater than several thousand astronomical units ...

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 ...

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 ...

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 ...

The European Space Agency (ESA) wants to land a tiny mobile phone-sized satellite on an asteroid to measure its gravity. Thus, measuring the gravity will be no easy task, as the gravity on a body such ...

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 ...

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 ...

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 — ...

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 ...

Scientists have measured gravity at an extremely short distance, in what they hope will tell us more about extra dimensions. The rest of this article is behind a paywall. Please sign in or subscribe ...
