Energy is everlasting (1st Law of thermodynamics) ergo so is time but is time an infinitely long strip of rubber or is it a closed loop?

I personally don't know... but have you read The Fabric of the Cosmos? I'm not sure who it's by, but it's incredible and has all sorts of theories, like how time and space are so closely related that they may be just one entity and this entity can be described a the spacetime loaf? Recommend you read it, judging by the nature of your question, I bet you'll like it. x

I don't think anybody has an answer to this yet. I think Harking, at least, thinks that time curves round at the Big Bang, so that end at least is closed. On the other hand, there was a theoretical development reported recently in Quantum Loop Gravity which made the Big bang not go to a point, so time came through from a previous universe. So the answer is that physicists are still arguing pretty vigorously about it.

This isnt the first law of thermodynamics, btw, the first law of thermodynamics if I remember right is U = Q + W e.g. the internal energy gained by a system = the heat in + the work done. I dont think I could dervice e= everlasting from that, shrug edit my personal view is that time is independant of the universe, its intrinsically subscribed on some higher plane, say, brane world if you believe in that

everlasting energy coould b a thought a remember a moment u felt and could refeel when u remember???wat happens to a thought when u die??? wat do u believe??

Feynman* would say that 'everlasting' or 'infinite' (in any but the mathematical sense) are both metaphysical terms, and this class (Physics) doesn't do metaphysics. One is even reluctant to use the word 'permanent'. *paraphrase, not quote.

A.J. I think perhaps that you are not think it question through enough. If you were to graph time against motion/entropy Where: motion is the independent variable on the horizontal axis Where: time is the dependent variable on the Y axis. Then: as he motion / entropy tends toward zero, then time moves slower and slower. Without motion, you have a status in time. DURATION WITHOUT SEQUENCE. Submitted, Ed
