The gravitational constant describes the intrinsic strength of gravity, and can be used to calculate the gravitational pull between two objects. The gravitational pull between two objects can be ...

Gravity is the reason things with mass or energy are attracted to each other. It is why apples fall toward the ground and planets orbit stars. Magnets attract some types of metals, but they can also ...

Lagrange points are spots in space where the gravity of multiple objects basically cancels each other out from the point of ...

We are fascinated by the gravitational differences between other planets, but rarely do we recognize the gravitational variations upon our own. If Earth was a perfectly smooth sphere of equal density ...

ORLANDO, Fla. – Strolling along the beach, you find seashells and seaweed left behind by the receding tides at your feet. When you gaze up at the moon, you’re looking at the primary cause for the ebb ...

The first detection of gravitational waves in 2016 provided decisive confirmation of Einstein’s general theory of relativity. But another astounding prediction remains unconfirmed: According to ...

PITTSBURGH (KDKA) - When you're at the beach you undoubtedly notice what looks like the tide moving in and out. While it seems like the tides move in and out over the course of the day, the tides do ...

Here’s a Snapple-cap factoid that’d be fun to whip out in conversation: on a planet the size of a ladybug, objects would fall 30 billion times slower than they do here on Earth. And how do scientists ...
