I am in the process of reading an article in Scientific American which has some very interesting ideas on time that I never understood before (though I have heard of it).
A rough summary is:
The arrow of time is caused by entropy.
The laws of physics all work both ways, so we can think of time moving in either direction and the laws of physics still w ere is an infinite number of timelines, continuously branching, and we are on one of them.
Point 2 is known as the greater anthropic principle. It implies an infinite
number of divergences at each point in time.
If point 1 were true, that the passage of time forwards is just
an illusion it would beg the question, what driving force in 'the futuret'
is making us continue allong this specific path (as seen from our perception).
If point 2 were true we would need to ask ourselves if these dimensions
were actually separate to ours or somehow part of the same 'reality'.
Very interesting subject, I think some theoretical physicists might have
a good take on this.
My own take on this is to address the question 'are there infinite
possibilities in a game of chess'. Hypothetically the answer is yes but
as the piece shuffling increases towards infinity, so would the difference
between games approach 0. The idea seems to me to be inherently
flawed. I find it much more likely that conciousness has necessitated
the physical universe but then I smoke too much weed.
