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 ...
Quantum theory and Einstein's theory of general relativity are two of the greatest successes in modern physics. Each works ...
A: I have flown many times in zero-gravity airplane flights. Each time I still enjoy the feeling of floating free, the ability to fly across the cabin from just one gentle push on the wall, just like ...

Could gravity be a clue we’re living in a simulation?
Gravity is usually presented as the most familiar of nature’s forces, the quiet background pull that keeps feet on sidewalks and planets in orbit. A growing group of physicists is now treating that ...
General relativity has never been tested in places where the effects of gravity become truly extreme—for example, at the edge of a black hole. That will soon change Scientists have been trying ...
