Juvenal?

Aren't you the guy who wrote that Roman-Casse AAR in the TWCenter?

Yes, that is I, it was Juvenal's Journal.

You might recall that EB took a couple of years to deliver the first complete version (during which time RTR got all the way up to version 5). I joined here to get EB v0.80 and become involved in the EB community, but I ended up writing the AAR over at TWC because they had announced a competition.

I am mostly into IBFD7.03 at the moment.

Back on-topic, Time is a fascinating and elusive concept. We experience Time's Arrow as cause and effect, and yet our theories of physics seem to work for the most part equally well in both directions.

I seem to recall reading Feynmann writing about his Vacuum Diagrams, that he said a good interpretation for some interactions is to assume that some particles travel backwards in time so that they have a hand in their own creation!

AFAIK, the big exception to this being the 2nd law of thermodynamics. I have heard it argued that this is the reason why we perceive an "Arrow of Time" in the first place.

This is correct; in quantum field theory, an antiparticle is interpreted as being a normal particle travelling backwards in time.

I'm not sure whether this has any deeper significance however or if it is simply a convenient mathematical interpretation. However it is certainly true that particle physics, with the exception of the weak nuclear force, is time-reversible.

Gah! Blinded by science!

Actually two years will never be in the same frame because you can always have a smaller unit of time, than the one you consider.
For instance, you are talking in seconds...the 60th second of an year can be further subdivided into say milliseconds. Then the 1000th millisecond can be divided in microseconds, and then nanoseconds and so on....that last bit of time, which you are saying belongs to both years, will keep getting smaller and smaller infinitely.

Perhaps if we re-programmed the main deflector array to generate a tachyon beam we could create a time paradox allowing us to simultaneously be in two different times at, er, the same time.

If I speeded like the Flash by doing continous jumping jacks could I experience a different time to someone else who was stationary, maybe we could have two differ years together that way.

I'm off for a mass of red bull to start my experiments
