If the Earth were to lose its gravity, then a body near the Earth’s surface would face drastic and immediate consequences. Gravity is the force that pulls objects toward the center of the Earth, keeping them grounded. Without this force, a body would no longer experience weight and would enter a state of free fall.
In this scenario, everything ranging from individuals, houses, and other moving vehicles would start levitating in space and going off the Earth’s crust. This would be caused by a complete absence of gravity force. There is no pull to keep anchored any objects on the earth surface. Anything in motion will continue flowing without being halted by forces like gravity because it never acted in a pulling direction during the previous instance.
Moreover, it would have devastating consequences on the Earth’s atmosphere because gravity holds it there, and without it, air would dissipate into space, and people as well as other living things cannot breathe. Loss of gravity will affect the structural integrity of buildings and other structures leading to possible catastrophic failure.
In a nutshell, if Earth lost its gravity, all bodies would float into space, and life on this earth would be altered so much that it would never be the same, rendering the environment uninhabitable.
