Understand Worm holes in easy way

Many of you like me must have read Einstein theory of relativity umpteen number of times. However, every time we read, we get more confused. I have also tried my bit to understand the same and then tried to put the same in the sketch video - Same way my school teacher try to explain in example.

I would be welcoming your feedback on the same as I do not consider myself a physics guru but I consider myself a decent teacher, so whatever you help me understand, I will try to explain via this blog / video.
