What would happen if everyone lived in space?

  If everyone is living in space, the space will develop and develop, also it would be fun because there is no gravity and they will float in space!! Maybe somebody will hit by asteroids. The house will look cool. House will float in the space too and house will look like asteroid because there is lots of asteroid floating in the space. They will wear spacesuit.  They will eat food that we eat normally because there is no food in the space. (They might eat aliens.) They will take rocket to travel or some people will just travel by themselves. (Swimming)
