The Evils of Computer Simulation

Now I feel for the guys who recently simulated the entire universe from "just after" the big bang* (apparently a few hundred thousand years out is no biggie compared to the age of the universe - and any engineer will agree) until present day. That simulation involves a TON of variables. Even on a mainframe computer equivalent to 20 or 30 times the best Alienware computer, it took a week for the simulation to run. It then takes another few days or so to interpret the results. When I read the article they hadn't gone through the results yet. So, what if it turns out that they are wrong? They'll have to painstakingly go through all of their code and assumptions and then run it for another WEEK! So it could easily be on the order of a few months before they have a working simulation.
I'm currently doing a simulation that is nowhere near the magnitude of theirs. I'm just simulating a Bipolar Junction Transistor (BJT), which may sound daunting to the uninitiated, but is really pretty simple. Well, it's supposed to be simple. I've been at this simulation on and off for a few weeks not, trying to get it to work. It's really annoying because each time I change something and want to see what the result of the change is, I have to wait about 5-10 minutes. Then, if it's not right, I have to figure out what I'm doing, make a change and try again. It's quite annoying.
In comparison, I really miss my Java programming class. Every time I tried something new I would compile it and in less than two minutes I had a few errors that I could work on or if I happened to get it right, the program would run. Not only that, but a Java program, at least on the level of what we were doing, is a piece of pie.
Well, the simulation is giving me errors now, have to go deal with that.
*= I'm not arguing in favor of the big bang, it's just what they are researching. I think I have some posts about this, just not the time to go through my 500ish posts to find it...not right now anyway
