Concept of time

Based on hypothesis that Big Rip will tear apart the universe (which could turn out to be wrong), if we are *able* (?) to calculate when universe ends, call time "xx till EoU" (End of Universe) since the rip effect is supposed to be at whole universe scale.

This must have been thought about by the founders of this hypothesis, what you guys think about the 1st paragraph?

This is just for starters I'll add some thoughts later on.
 
Bah never mind, I can't really think of anything else about it at this moment. Except maybe a question about blackholes, will they rip apart sooner or later than everything else 😛 I'll try to read up some more material on this "Big Rip".

Time is best concieved as a circuit, or self-recursive, since there is no "reference frame".

I liken time and the experience of it, as if we were electrons in a circuit, going around the ring or an oscillating balloon that expands and contracts.

I try to think of time from a video game perspective, time in video games happens in discrete instantaneous moments from one to the next. It makes a lot of sense if we try to think of time (and even the universe) as a simulation, and what we understand as time, as an energy distribution flow over a 'grid' of timespace-locations... there's been a lot of hypothetical discussions of the universe being a simulation online away from the narrow minded academic constraints of academia.

The best thing is to use geometry, nature is geometrical, therefore, to understand time, try understanding how movement occurs in a grid in geometry (especially in relation to video games). I think computer science/video games/simulations will have a lot to teach us about physics personally that we don't fully understand yet.
 
I had a pretty cool experience with kind of thing you are talking about(but not exactly), Gannon, in video game. I was playing cs source, and had very huge lag for 10+ mins. One moment I was standing still then after a few seconds I zoomed right into direction where I was supposed to be, every action unfolded but 10x as fast as real time. It was pretty cool, but obviously unplayable because I only learned how to play in real time 😛 And of course the time didn't "truly" slow down for me, it's just the server couldn't keep updating positions of players real time and transfer that information at the same rate to my computer.

The only thing I couldn't do was go back in time, otherwise time was speeding up incredibly fast, slowing down or standing still, while everyone else in the game were experiencing steady passage of time. This is kind of like what Einstein said in his relativity theory, passage of time is relative to the observer.

Well, there isn't such a game invented yet where everyone gets sent back in time and all actions are undone. At least there would have to be some kind of markers or it would be a replay.

Which leads me to a simple reasoning: IF we are able to go back in time, a mechanism for observing the past (events that unfolded) would be easier to achieve than actually going back in time and change the outcomes.

Exactly, which makes me think that when einstein said "time slows down at the speed of light" what he really meant was that "energy flow updates" slow down.

It makes a lot of sense when we think of it as a video game lol. 🙂 which makes me wonder, is space-time actually a series of discrete, out of phase probabilities? hmmm.

Google "quantum loop gravity". Time and space are discrete in QLG, IIRC.

If time is discrete, is it an all existent? i.e. does time itself have energy (in QLG)?
