New claims challenge inconsistencies in one of the foundational principles of physics. Albert Einstein postulated in his 1905 ...

Despite dozens of experiments over the years, scientists still don't have a precise measurement for gravity's strength. Why is that?

As far as we know, our physical world is governed by four fundamental forces: electromagnetism, weak and strong nuclear forces, and gravity. Apart from playing with bar magnets or marveling at the ...

Scientists are now developing spinning space stations with artificial gravity that could take astronauts deeper into the ...

For decades, engineers assumed gravity played an indispensable role in boiling-based cooling systems. On Earth, rising vapour ...

Heading into space means leaving Earth's gravity behind. Astronauts floating around on the International Space Station might look like they're having fun in the weightless environment, but a lack of ...

In the April 1981 issue of Popular Science, we explored the many initiatives and techniques used in the exciting hunt for sensing gravity waves, then out of reach. By Bill Gourgey Published May 18, ...
