Seems like I opened a can of worms here.
It's not too hard.

You can try and ridicule me all you want and it just makes you both seem like baboons.
It is a logical explanation of the existence of everything. Just as good as any explanation they can teach at school, church, home, corner store, crack pipe, ect...

P.S. Yes, I am agreeing with Yung.
Posted 16 September 2012 - 11:04 AM
No, you're not.
Yung stated that "time is just a concept", which it isn't. It's a fundamental property of the universe.

And now we're on to semantics. Riveting discussion this.

Ah, someone that knows enough to catch me when I over simplify. I should have said that some interactions of subatomic particles occur without respect to the arrow of time.Coltrom: Just as a clarification, time symmetry is not always found in the interaction of subatomic particles.

All well and good, but you're yet to explain how a civilisation could explore 3.817×1032 ly3 of space in under a million years, without exceeding lightspeed.

Dark energy is causing the accelerated rate expansion of the universe, does not an expanded universe have more entropy? Since we don't know what dark energy is, only what it appears to be doing, .,.,Coltrom: You might have misunderstood what I said. It is not that time is a product of entropy, but that the direction of time is probably found from entropy. Time itself is understood as just being the 'fourth' dimension of the 4D manifold of general relativity. The trick of time travel in this understanding of the arrow of time would be to just be in a near maximal (global) entropy state, as a state of maximum (global) entropy does not have a preferred direction of time except for the mentioned rare particle events.
Lowering entropy in one area does not allow for time travel, as any process that requires the input of heat (such as any endothermic reaction) generally involves the local decrease of entropy but none of these processes are evidence of time travel.
Dark Energy is a concept unrelated to the direction of time, and also unrelated to the concept of entropy.

Sweeney, if you are going to give the number you might as well give the more accurate one based on the evidence we have which has a radius of about 46 billion light years, due to the wonderful expansion of space is much larger than just using the age of the universe estimate.
So, given the age of the universe, the amount of time for civilizations to evolve, and even with no FTL travel ram-jet fusion ships could have explored the whole universe, with self-replicating machines to either watch, conquer, or just play head games, WHERE ARE THE ALIENS
P.S. Assume top ramjet speed of .1c, with solar deceleration greater than acceleration, assume a self replicating machine, producing multiple replicators at each G-class star. Then the total exploration of the Galaxy takes less than 2 million years to explore. Since exploration is done by sentient replicating machines, there isn't even the need for the host/creating species to survive.

I used an estimate of 45 billion lightyears, from memory, apparently slightly out of date. Apologies.

My discussion, and Niven's Pohl's or Clarke's discussion of exploration has to be limited to the Galaxy. While the Galaxy is a small, small sliver of the Universe, most still believe large enough for there should be elder civilization, unless.,,..,
