According to legend, Galileo dropped weights off of the Leaning Tower of Pisa, showing that gravity causes objects of different masses to fall with the same acceleration. In recent years, researchers ...

A new look at da Vinci's papers reveals his insightful attempts to probe the nature of gravity 500 years ago. Engineers from Caltech have discovered that Leonardo da Vinci's understanding of gravity - ...

A team of engineers studying the 500-year-old, backward writings of Leonardo da Vinci have found evidence that the Italian polymath was working out gravity a century before its foundations were ...

Physicists have designed an experiment that could detect graviton, a particle that carries the force of gravity. If it does actually exist, it has eluded researchers for more than a century. The ...

In 1797 Henry Cavendish, one of Great Britain’s leading scientists, built a contraption to weigh the world. At the time, Earth’s mass was unknown, as was its composition. Was it mostly solid rock? Did ...

Forbes contributors publish independent expert analyses and insights. The Universe is out there, waiting for you to discover it. Can you please explain to us how awesome this is, and what you hope the ...

All of the objects in our solar system are acted upon by forces. Forces are pushes or pulls. Every force has both a strength and a direction. Applying a force on something–like pushing a toy car–can ...

There are certain physical phenomena we take for granted, like gravity tugging us to down to the Earth, or the refraction of light coloring the sky blue. INVERSE IS COUNTING DOWN THE 20 STORIES THAT ...

Gravity is the weakest of the fundamental forces, but it's the only force that operates over very long distances. Hence, planets orbit stars, stars form galaxies, and galaxies cluster. Gravity also ...

I had an interesting thought, spurred on by a discussion I ran across online about firing guns in space. Apparently, smokeless powder contains its own oxidizer and so you could shoot normal firearms ...
