STEP 2: Stand on a sheet of paper and use a pen and a ruler to draw a rectangle around the ... Mass is a measure of how much matter there is. Gravitational force is the pull of the Earth's gravity ...

The rest of the universe appears to be made of a mysterious, invisible substance called dark matter (25 percent) and a force that repels gravity known as dark energy (70 percent). Scientists have ...

Researchers have developed a new quantum theory of gravity which describes gravity in a way that's compatible with the Standard Model of particle physics, opening the door to an improved understanding ...
