Question

What will happen to the world if there is no friction?

Answer 1

If friction is not present in the whole universe, then nothing would have happened. Nobody in the universe will be able to move, because it is with the help of friction we are able to move. Imagine all the bodies staying at the same position forever. This can only be possible if we remove friction from the universe.
You are able to move because when you push ground backwards, the friction from the ground helps you to move forward. Without friction there will be no force on you by ground which will make you move forward.
