commonly known as relative density, specific gravity is the ratio of density between a particular object and a standardized object such as water and air, acting as a basic comparison. To understand ...

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 ...

A device that can measure the gravitational force on a particle that weighs less than a grain of pollen could help us understand how gravity works in the quantum world. Despite keeping you stuck to ...

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 ...

Despite having a surface temperature of around 5,505°C (9,941°F) making it impossible to host human life, astronomers have been able to determine how much an average person would weigh if it was ...

This story was originally published by Inside Science News Service. Henry Cavendish was an odd man. He never addressed strangers directly and was petrified of women. He had a staircase built into the ...

Heavy duty: Ultracold atoms could soon be making gravity anomaly maps like this one of Australia. (Courtesy: Australia Geoscience) The curvature of a gravitational field across a distance of about 1 m ...
