What would happen if we didn't have gravity?

Answer 1

If we didn't have gravity, all objects on Earth would float off into space in a straight line at a constant velocity. Without gravity, there would be no force keeping celestial bodies in orbit around each other, leading to chaos in the solar system. Additionally, the absence of gravity would have profound effects on the human body, as our bones and muscles rely on gravity to maintain strength and structure.

Answer 2

Without gravity, none of the stars or planets would maintain their forms. Gravity allows the Sun to maintain its energy generation while remaining as a single mass. Gravity allows the Earth to hold its atmosphere.

Indeed, gravity is the force that forms stars and planets, although the trigger that begins the process is still unclear.

Answer 3

Without gravity, everything would float away into space, including our atmosphere and the water on Earth. Without gravity, there would be no force holding objects together, and planets would not be able to orbit the sun. Life as we know it would not exist without gravity to create the conditions necessary for it.
