No, what it has almost finished is using the Ore Dictionary to duplicate the worldgen. So it'll keep your basalt and marble and gems and nikolite... that's about it.(For the Inevitably impatient) This is pretty cool. http://forum.feed-the-beast.com/threads/1-5-2-numirp.22233/ it isn't that old but it has already almost finished the RedPower world replication.

I'm the Doctor. I'm a Time Lord. I'm from the planet Gallifrey in the Constellation of Kasterborous. I'm 903 years old, and I'm the man who is gonna save your lives and all 6 billion people on the planet below. Got a problem with that?
I currently have about 22 days worth of audiobooks to listen to. (A fact which I'm sure to forget next time Audible has a sale...)
I'm special. I'm sexy. I'm fabulous. I'm hair. I'm honest. I'm brave. I'm above the influence. I'm so high I'm above the influence.
I first knew I was special when someone told me that audiobooks aren't for reading along. :c
Time Travel Issues...Once I saw part of an episode. But somehow I'm not confused. Because I think about time travel issues far too much.
I haven't read Pratchett. Most of the scifi I've read lately has been Weber.
Time Travel Issues...
Whenever I see a Time Travel movie, like Meet the Robinsons.
In Meet the Robinsons, after all the events caused by the future existence of a robot by the name of Doris happen, the future creator of the robot decides that he will never create the robot, and so the robot winks out of existence.
So how would the events leading up to the non-existence of Doris ever happen if Doris never existed?
The boy would never decide not to invent Doris, and so Doris would be created, and all the events would occur, etc. etc.
Le sigh.
Indeed, this "winking out of existence" thing doesn't make any sense, because it's not just the robot that depends on its future creation, but the entire history of the timeline. Logically, time travel can't change anything, but authors come up with various literary devices (such as BTTF's "ripple effect") to try to get away with causing time travel to change just the things that are narratively convenient.

Every action you change makes a new timeline. There's the old one, where the bad stuff still happened, and then the new one, where the bad stuff didn't happen because the other timeline said "nope not allowed".
It may be depressing but it's not, really.
Le sigh.
Do we all forget that there is no public Xycraft release for any version of 1.5 minecraft? Why does all the hate go to Eloraam and not Soaryn? Because you see him on Dire's channel?
Movies are never right.
Loop:
Logic:
- Doris is created in 30 years.
- Doris travels back in time and does stuff and things.
- Doris Creator decides that because of the stuff and things Doris did, he should never create Doris.
- Doris disappears.
You can continue the loop.
- Doris existing -> Doris does bad stuff.
- Doris doing bad stuff -> Doris Creator never creates Doris.
- Doris never existing -> Doris never does bad stuff.
- Doris never doing bad stuff -> Doris Creator never has incentive not to create Doris.
- Doris Creator never having incentive not to create Doris -> Doris exists.
The only issue with the many worlds view on this is the inconceivable number of worlds that would get created ever Planck. It gets really really huge vary vary fast. It is not just in the planck you could have chosen two things. It that everything in the universe could have done multiple things at that moment and each one gets it own new world.
Considering that there is actually no way to reason about anticausal subjects outside of the most simplistic quantum effects (in a universe we experience as causal, using brains evolved to be spectacularly specialized for seeing causal relationships even when they are not there) save by mathematical esoterica that less than 100 people worldwide truly understand, let's err on the side of drama.
Yep. The way I think of it, there are septillions of alternate universes where the only difference you can pick out between any two is the spin of a single atom in a star about 60 billion light-years away. Which means that the majority of travel to alternate universes is going to be rather boring, since unless you're insanely lucky, you're going to end up in a world that's insignificantly different to yours.
Yep, the loop essentially makes a Mobius Strip through time. But writers often follow the illogic of "the time traveler can't have existed now, so they suddenly don't" when the reality is that as soon as a time traveler arrives in the past, the future is different so they can't have arrived in the past. Or else it's now a different past and therefore nothing they can do can endanger their existence. *shrug*Movies are never right.

I think that's based on a misunderstanding of what a 'world' really is, in the Many Worlds Interpretation of quantum mechanics.The only issue with the many worlds view on this is the inconceivable number of worlds that would get created ever Planck. It gets really really huge vary vary fast. It is not just in the planck you could have chosen two things. It that everything in the universe could have done multiple things at that moment and each one gets it own new world.
TL;DR if there's more than one way the universe might get to the same place, the chance of seeing one of them is found by adding the probabilities of the different ways of getting there, but if different paths lead different directions we only ever see one.
Snipped the wall of text not everyone is going to want to read that twice.
But yes in current quantum theory most of the time MWT is used to explain the probability of events and not actual extra worlds. But there is also some thought going into parallel world theory (at lest among those that believe in parallel realities). It issue is to most these two theories blur over. I mean you bring up M Theory and most people will glaze over.
