Damn, that's the best farming simulator I've ever seen.
Really, nice game. I like the art style, its simple and playful. Weirdly matching the game play.

It is certainly a very deep question.

Currently, for us to create semi-accurate simulations, we have to understand all the parts of the object we are simulating. Since we do not actually understand all the parts of the universe, I'd say that currently making a simulation is just plain impossible. So, currently, I believe it is impossible for human beings to create a valid simulation of the universe. (Maybe parts of the universe, but not as a whole.)

If we expand this question to the future...

Understanding of the universe and all its parts will completely remove the need for a simulation. If we knew how to create our own planets, our own stars, etc. Chances are we would just choose a section of the universe and create a real-life simulation on it. There would be no need to recreate it on binary when we can just use the universe as our playing ground.

Honestly, I believe the human race will cease to exist by the time this is figured out. Computers, no matter how advanced they are, have a weakness that they can only be represented in a series of numerical bytes. Recreating something like the universe on a machine with limitations only limits what you'll be able to create.

As far as we know, the universe is still expanding. Even if we dedicated all our current computing power to this, it probably still wouldn't be enough Tongue...

Let's assume that we had a simulated universe running on a computer. A fully deterministic universe without any quantum randomness.
We have an initial state S and a function f that transforms the current state into a future state. f contains therefore the complete laws of physics of that universe.
That means any event that ever happens is fully determined by S and f alone and completely independant of the computer.
One question here is - what happens when intelligent beings evolve in that simulation? They would not be able to determine if they are simulated or not.
Again - anything that happens depends on S and f alone. So they couldn't possibly build an instrument that measures anything that isn't derived from S or f like for example the computer or the outside world.
The paradoxical thing about this is - Even if they somehow came to the believe that they are simulated, they wouldn't be able to tell whether the simulation is running or not, or whether it ever run at all. Because that information is not contained in either S or f.

Wish I could give you another medal Cero.

Found a bug when i try to run it
java.lang.IllegalArgumentException: timeout value is negative
   at java.lang.Thread.sleep(Native Method)
   at Source)

Doesn't seem to be a problem thought it's only started as negative

Thank you for your report.  I am aware of this bug, and it will be fixed soon.  However, it is not high on the fix list at this moment.  I am currently working on a multilayer feature this is currently top priority.

@opiop: You are right. You dont seem to have got what I mean, but probably because I explained it bad. Let it rest in peace please.

@SimonH: Nice to see somebody back on topic. (Edit: Cero too.)

No, not the universe. Some physicists believe they have a pretty good idea of what the universe is and where it came from.
Reality. The existence of the universe requires at least one thing: Existence.
Not time or space but pure, meaningless existence. This is a paradox.

You are right, of course. However thats not a paradox just something beyond our grasp.
Our universe is the only amount of reality we know, there might be more, that universe is expanding "into" existence a room of existence if you will.
why that room is there or how is a question but not a paradox.
the universe could also turn non existing space, negative reality if you will into positive while expanding, during that process
point is yeah, we dont know but I dont see the paradox. A paradox implies that assumption A and B are both right but cancel each other out. like the drake equation
I mean our definitions of reality and existence are getting kinda muddy because we are wandering into philosophy since we are not that far in science.

Thinking about it some more...
Some of the most powerful computer systems are simulating the weather on earth with a pretty good degree of (short-term) accuracy. As CPUs get ever more powerful, it's reasonable to assume that models (rather than a simulations) will be made of the universe. That could get interesting! In the same way that our weather models showed the el nino current to be highly significant to our climate, maybe universe models will show us things we never guessed at? Wormholes maybe?

That was just offensive Drenius. Do you know how the universe works? No? Then don't tell me I don't either.
