If you drop an object, it will fall. It's a motion that we’ve all seen hundreds of times. We’ve also all seen plenty of the moon, which makes one complete orbit around our planet every 27.3 days (as ...

As the story goes, Italian astronomer Galileo Galilei ascended the Leaning Tower of Pisa in the 16th century to drop two spheres of different masses at the same time—proving that they would land on ...

We know “what goes up must come down.” But WHY? "Drop" in to find out! We know “what goes up must come down.” But WHY? Drop in to learn about the gravitational forces like acceleration and air ...

Anyone who has watched Matthew McConaughey plunge into a supermassive black hole in "Interstellar" may think they have a rough idea of what it'd be like to encounter one of these terrifying cosmic ...

Gravity doesn’t discriminate. An experiment in orbit has confirmed, with precision a hundred times greater than previous efforts, that everything falls the same way under the influence of gravity. The ...

Our motion perception is remarkably well tuned to detect small changes in speed and direction. For example, soccer goalkeepers need to precisely judge the speed, direction, and curvature of an ...

An experiment has visualized a prediction about objects traveling at the speed of light known as the Terrell-Penrose effect, ...

Seismometers over Los Angeles awakened on April 2, 2024, with unusual blips. An earthquake would have been a reasonable cause ...
