Oooh! Oooh! My turn! My turn!
Lemme take a shot...
I've had several ideas of time travel and to me it involves that parallel dimensions to our own are all within the dimension of quantum physics. The dimension where anything can happen and in constant flux and it's impossible to predict anything. I think the exact moment is when the parallels cross and quantum occurs before the parallels level off. The quantum dimension is constant.
It's kinda like the parallels (including our own reality/dimension) are a school of fish swimming in the vast ocean (which the water represents the quantum dimension/energy or time)
Now say I alone or We represent a whole but multiple parellels... One school, but individual fish.
Now say we come across an identical school... We swim at each other. We can't exist in the same line or directions so some go left, right, up, down, loop-de-loop, some eat the other in their way, ect, ect.
This is the exact moment within the quantum that occurs. That 'coincidene' that comes and goes.
I turned left, while my parallel counterpart turn right. Live die. Quantum is the balance of the actual moment in endless flow of time across dimensions.
What happened and didn't happen here happened elsewhere...
I believe it was Morpheus who said: "It happened no other way than it could have happened."
"How do you know that?"
"We are still alive."
Whereas elsewhere... They we not still alive.
Well, that's my bit on Quantum Dimensions and Time. Next: Space-Time vs. Time-Space?
