Einstein’s theory
I saw most of the people being concentrated on Newton’s gravity only. So I decided to describe it with the help of Einstein theory……..

But in real there is not such fabric in space. It’s just supposing. In my view, this is due to the displacement of force of fourth dimensional space which is caused by huge masses like sun and other stars due to their huge masses, which causes conical surface same as in the fabric. The huge mass causes to displace the curved force and that force is displaced to other place creating a depression on its original position that totally creates a conical surface. Same as a fabric, the displaced force created by huge mass and the original curved force of fourth dimensional space exerted on the planets tries to hold the planets above the huge mass so that they tend to revolve in that conical area continuously. This causes the planets to revolve around the stars and satellites to revolve around a planet which is the main reason for them to be round.
Newton’s theory
According Newton’s, law of gravitation anything having mass exerts gravitational force towards another mass. This force tries to attract everything towards its centre. This force is distributed everywhere around the body. It’s not one sided. It is like a magnetic force in small area where it attracts magnetic substance from all sides rather than a one sided vacuum cleaner which attracts the things from one side only. As this force is distributed all around the mass it tries to collect mass from all sides which are collected in all parts of the surface of mass and again a mass tries to be collected at the centre due to the influence of gravitational force so it remains on every part of the surface. Due these reasons the mass forms roughly a sphere. So everything in this universe tends to be in spherical shape. Also small droplets of water in leaves tend to be in spherical shape due to their freely moving molecules but it is not so in more amount of water because more gravitational force of earth is exerted on it. This is also due to the curved force illustrated above.
You may be thinking why the substances like brush, doors, utensils etc in the earth are unable to be sphere. This is because they have very less mass due to which less gravitational effort is applied between their smallest components. Also they don’t have free molecules like water. So it doesn’t become sphere. So, small rocks in the space are also irregular in shape. The last and most important thing is our earth is also not totally round because its rotation makes it having greater radius at equator. It is roughly a sphere.
