Without the existence of gravity, our muscles and bone deteriorates. All the evidences say that we couldn’t exist for a full lifetime in a state where we are weightless. Evolution has developed us (all the living beings) to live in the presence of gravity. (Clegg, 2012) once said, “Without gravity pulling down on the internal organs, lung capacity is reduced by a change in position of the diaphragm, while the liver floats higher in the body cavity leaving even less room for the lungs to function. A baby born in space may have seriously compromised ability to breathe, which combined with bone deterioration emphasizes just how much gravity is part of our natural environment.” So to finally say, gravity is as essential and significant like the air we breathe. This is one of our requirements to live. Before, I learned that I only need food, water, shelter, air and clothes now I need
