There are 2 types of Universe we can exist in, one where we only think we are making choices and one were we are actually making choices. The one where choice is an illusion means that there could be a map or plan to the Universe, the other anything that could happen might. If the Universe has a plan then we are obviously not privy to it, if anything can happen then what are the consequences?
From our perspective every action or choice will spawn a different universe, over the space of a few seconds the changes will be negligible, but over say 100 years they could be huge, for instance if a regiment of WWII soldiers went left instead of right perhaps we might have lost the war and be in German occupied Britain.
This would mean from this second onwards the timeline would look like this:
However if someone looks back from the future then the present looks just like our past. The reason is only 1 of the paths diverging from our present ends in the future when the observer is from. So ‘if’ time travel is possible then the future boy in the present could only get back to the future where he came from if everything happens just as it did for his past.
In a pre-determined Universe no matter when you go you can always get back when you came from. Thus it is a much simpler Universe to live in however since when has the Universe been simple?
We’ll be exploring a variety of problems based on these premises in some upcoming blog posts.
