Many
believe there is no gravity in space. Astronauts appear weightless
in space, so there is an assumption that space is a place with
zero gravity. That assumption carries no weight.
There is less gravity in space, but the idea that there is none is
factually incorrect. There is gravity on Earth, on the moon, and
on the sun. It all around us. The reason why space allows humans
to be weightless is because they are gravitating toward the Earth
at the same rate as their ships.
