P.S: Just a change of mood.
Newton questioned why apple falls on the ground and deduced that smaller objects get attracted to larger heavier object. But he never explained why.
Einstein explained it as follows with a very simple illustration. Imagine space-time to be a large white bedsheet (space-time fabric) and all the objects, our planets, suns be placed on that bedsheet.
Now if you place a heavy object on a bedsheet, it causes a depression and the lighter objects get attracted to it. So earth causes a depression and sun causes a bigger depression and earth gets attracted to the sun and spirals round it. We as humans are so light that we cause a depression that nobody cares about and we remain glued to the earth.
A blackhole is a very heavy object and huge depression in the bedsheet and anything that comes near it gets sucked in.
Now this space-time fabric will be infinite so spherical. A wormhole is a depression that goes from one end of the sphere to another end. So if you enter a worm hole you can reach the other end of the universe.
