Gravity/ Antigravity

On the earth and other planets; and some stars, there is an electromagnetic force that pulls objects towards the centric portion of the planet. This is called "gravity. In space, the gravitational pull is outwards. Gravity pulls outwardsly in all directions instead of in a collimated single direction downwards pull. Breathing is more difficult in space due to the outwards pull. Space is created from hydrogen which complicates breathing further.
