Hi Everyone. I have two questions for the astronomers /scientists within the forum. I have recently watched one of the plethora of programmes about the universe which are on television.
Question 1. The Doppler effect/shift, I don`t quite understand the reasoning behind this? Answer in laymans terms please.
Question 2. The big bang theory and expanding universe. I assume when scientists refer to this they mean our universe or known universe. Now here is what confuses me in my own simple way I imagine a crossroads in space and me standing there. I look left and right, up and down and see the same thing in every direction. But this is what puzzles me, are there spacial gaps between universes and if this is so and taking the big bang and expansion theory as a premise, are scientists saying that this law is not universal but only applicable within their own universal theoretical limitations? I may not have explained myself very well but answers please in terms I understand. Regds N.
