Gravity used to be the most down-to-earth of ideas, the thing that kept apples falling and planets in line. Now a growing ...

I was actually asked this question yesterday by one of my physics students. He was surprised to see a figure of 32 in his pre-calculus book associated with the acceleration due to gravity on earth, ...

Gravity is usually presented as the most familiar of nature’s forces, the quiet background pull that keeps feet on sidewalks ...

The idea is still new and requires a lot of assumptions in its calculations to make it work. Over the years, experimental results have been mixed. When you purchase through links on our site, we may ...

Science journalist Nadis and Tsinghua University mathematician Yau follow up 2019’s The Shape of a Life with an esoteric exploration of geometry’s role in explaining gravity and the structure of the ...

The idea of emergent gravity is still new and requires a lot of assumptions in its calculations to make it work. But if experimental evidence ever proves it real, we would need to totally rewrite the ...
