View Full Version : What exactly did Rodney do for 25 years?

He already knew John was 48000 years in the future. They already know about solar flares and presumably Atlantis has the equipment to predict them. All they really needed to do was wait for the right hologram technology.

So what exactly did Rodney do after Jennifer died.

Oh and did anyone else guess taht Rodney and Keller ended up together jsut from him calling her Jennifer at the start?

If you followed the ep, he was spending most of his time working on a way to get Sheppard back to his own time.

He said somewhere that he had to invent a whole new math in order to do it...That could take some time...

A whole new Math to do what though? Calculate the type of solar flare needed? Something we've seen carter do in a space of 5 minutes? I don't buy it.

Well, Carter needed the Ashen computer core to do it since earths own wasnt complex enough.
So maybe he needed something new to be able to program it into the Atlantis core, or he needed it to create the new hologram tech or whatever =)

Great point.

Precisely, I do not recall what he needed to invent the new math for, But for some part of his plan, he needed a new math, Which, we have seen him do once before...but he was half ascended at the time...

As for the carter thing, She never really predicted one, she just told the computer to do it, and it was an aschen computer, so it was WAY more advanced than anything we've had...

Besides, in 2010 they were only sending a message back roughly 10 years through time, whereas Shepherd had to be sent back 48000 years. Bit of a difference one would think, and I could imagine that the calculations would have to be far more detailed to make sure Shepherd goes through the gate at exactly the right time to be sent back as close as possible to when he originally should've arrived in Atlantis.

He needed to create an interactive hologram program that would be able to assist Sheppard in returning to the past. He would have to be able to compensate for a number of variables, detect solar flares, inform John everything that would happen so that he could prevent it, and maintain himself indefinitely.

Yeah, that hologram had to be more complex and interactive than any yet seen.

Both the SG-1 time travels were relatively short jumps (30 years and 10 years) that could rely on any average size star making the solar flare. Sam used the Aschen computer to predict when a solar flare would occur for our sun, and Hammond used future knowledge for the flare in 1969. In both situations the exact time jump was unknown, the Aschen note just had to go back before they met and 1969 they botched the jump and went to far, requiring future Cassandra's help to send them back.

In Sheppard's case, it would have to be an enormous and peculiar solar flare to go 48,000 years. McKay had to calculate the conditions to send Sheppard back with a margin of error of only 0.16 years, with the amount to send him back increasing for every year Shep was in stasis. So Rodney had to calculate exactly what type of solar flare he needed, what suns could make it, predict when they would happen, and adjust for the addition of the stasis time. So ultimately 48,700 +/- 0.16 years.

He had to program the hologram system to be as human as possible. That's complex coding.

A comprehensive and excellent analysis, Mal.

Coding isn't the sort fo thing that requires a new math though.

And the solar flare thing, thats not how it works. The calculations don't get more complex jsut becasue it's a larger distance, thats not how time works.

He also had to do the math with no reality-based test and trials, for an application using stars in another galaxy. Then he had to put all of it in the hologram's matrix along with his knowledge and memories, plus make the preparations to ensure it would last for 50,000+ years. McKay accomplished this in less than 3 decades without access to SGC or government resources.

This trumps any solar system destructions or any other feat in the "Who's the Better Scientist" debates.

To ensure that what happened by "accident" will be repeated by precise calculation. Solar flares cause time travel but they don't guarantee that you will return exactly where you begin.

All modern programming languages are based around lambda-calculus. The currently held theories of computability state there are infinitely many calculations that are not possible. If McKay wanted to do such calculations and had managed to work out how to do it he would certainly need a new system of mathematics before he could get a computer to actually crunch the numbers. I'm not sure the writers were really thinking along these lines but it is logically plausible

The calculations don't get more complex per se but you have to be much more accurate over a longer period because minor errors produce an increasingly inaccurate result. In particular it is worth considering that a number of mathematical problems have solutions that take an extremely long time to return a result (e.g. the travelling salesman (http://en.wikipedia.org/wiki/Travelling_salesman_problem)) and usually heuristic algorithms are used which are inherently inaccurate.

To me it's plausible but I happily admit I'm not the most nitpicking viewer
