Photos and videos of astronauts on the ISS show them floating around, but saying there's zero gravity isn't fully accurate.

Even in some of the most extreme areas in the universe, Albert Einstein’s theory of general relativity seems to hold up. A test of a key tenet of general relativity using three stars has shown that ...

All objects in the absence of air resistance (friction) fall at the same rate regardless of their mass. Due to gravity the speed of an object dropped from rest from a height will increase at the rate ...
