In the zero-gravity airplanes or vomit comet, why does stuff behave like there is no gravity when it is just falling? – Austin B., 11, Scranton, Pennsylvania I have flown many times in zero-gravity ...

In a bold step toward solving one of science’s most puzzling problems, researchers have proposed a new way to bring gravity into the same mathematical language as the other forces of nature. While the ...

Gravity warps space in strange and counter-intuitive ways, and the bigger the source of gravity, the bigger the warping. One example of gravity’s optical illusions is beautiful rings in space named ...
