Noone has experienced 'zero gravity'

Gravity on a Space Station is roughly 90% of what it is on the Earth's surface, a far cry from 0! You and the Space Station are continuously falling together. Your sideways velocity is so high that you fall just as fast as the Earth curves with gravity always pulling sideways relative to your velocity. So in actuality astronauts have experienced perpetual falling without hitting the ground, not zero g.

You can't feel gravity directly, though you can feel it indirectly. such as your feet pushing against the Earth's surface as gravity tries to accelerate your body.
