Would "Entropic Cascade" happen eventually ?

[JoseP927]

Wonder what happen when two exact matter occupy the same space?
If the Shuttle and the duplicate crash into each other , would the fabric of the unvierse get tare apart?

You'd get a big spark due to the Blinovitch Limitation Effect.

It's still an alternate universe. We're just seeing them from different lengths of time away from the branch points. Take There But for the Grace of God, an alternate universe episode involving the Quantum Mirror. There's no deep, fundamental difference in that universe. Humans still breathe air, the galaxy is still ruled by the Goa'uld. But minor differences years before the episode is set (alt Sam not joining the military, alt Daniel being a jerk to Catherine instead of joining up) result in a branched timeline and its own distinct universe.

It's the same principle here, and in every other time travelling episode. Just because we're seeing the result more immediately doesn't make it any less of a distinct universe unto itself.

Alternate timelines are not Alternate Universes. Each time that the timeline is changed, the new timeline replaces the previous one, there is only ever 1 timeline per universe. Whereas alternate universes are always existing side by side with our own universe.
The quantum mirror or the alternate reality drive could not be used to travel to an alternate timeline like the one from Moebius or Continuum, because these timelines no longer exist.

We don't actually know that. Some would argue that when you go back in time a new time line splinters off from the original one, leaving the old one intact.

Yes in real world time travel theory, that is one possibility. But we're talking about SGverse here and within the SGverse it has been shown time and time again (pun not intended, but I like it) that when a new timeline is created it replaces the old one.

Only from the view of the time traveller.

If alternate diemensions exist then each version of the timeline would still exist. In fact it would have to exist to makes sense for two destinies to exist in the same timeline, as if there was only one time then the event of the destiny showing up 12 hour early could not happen if the accident did not happen.

If destiny did not travel into the star and open a worm hole, how did Destiny and Rush time travel 12 hours in to the past. An Telford to Earth.
For this to make sense both time lines must remain intact, because the cause of the event must still happen for the event to occur.

Got feeling the cascade will be ignored for plot convenience on this occasion, like in every other occasion where it would cause series problems to the story.

In theory through Cascade could have more to do with two masses trying to deplace each other from the same universe. The two carters guest that the further away they kept from each other the slower the cascade would get.

If you were to spread out one of there mass through the entire universe I doubt the Cascade would continue to effect the person or if it does it would be at a much lower intensity. A other way if could reduce the mass of one of the effective persons to zero this would also most likely block the effect.

If this was true, both Rush's could not co-exist, nor could two Destinys. In Time, they would find only the kino that they sent themselves, not the one from the previous timelines. It would be like Back To The Future when Marty would just vanish.

I can't wait for the season three episode where the original crew of ancients gates in.....

[General Jumper One]

There is no season 3...

[JoseP927]

WHAT?? NO SEASON 3??? No way! There will be 10 seasons just like SG-1.

[General Jumper One]

WHAT?? NO SEASON 3??? No way! There will be 10 seasons just like SG-1.

I wish, but no renewal for season 3 is bad news, and all we got for now is bad news.

That's not how Stargate time travel works. The 2 Rushs and 2 Destinies could coexist because the version from the future had traveled back. The timeline it came from no longer existed but it could exist because it had gone back and caused the new timeline.
The moment that the past is changed, the entire timeline is replaced with the new version, the only thing which remains of the previous timeline is the actual time traveler(s) which caused the change and thus exist within the new timeline, this has been demonstrated many times through SG canon.

In Moebius, the original SG1 changed the timeline in Ancient Egypt, nothing from their original timeline remained however they still existed in Ancient Egypt because they had caused the change. The same thing happens with Weir in Before I Sleep and Mitchell in Continuum. It's really not that complicated.

As for the episode Time, it contains 3 timelines and breaks down like this:
The first timeline where they get stranded and die, Rush and the Kino go back in time.
The second timeline which contains all of the events of the episode where the crew find the Kino and Rush's decomposing body. They watch the events recorded on the kino and eventually go back to the planet, Scott records instructions and sends a kino back in time.
The third Timeline is where everything works out fine. Because timeline 3 is a slightly altered version of timeline 2, and the past of timeline 2 contained Rush's body and the kino from timeline 1, then these thing also remain in timeline 3.

Entropic cascade only applied to alternate universe matter, anyway. This is same universe, different timeline matter.

I know this has been said by a few others but..

An alternate universe was spawned the moment that Rush came back and told the approaching destiny not to bother. That made his future different to their future which mean that another timeline was spawned running in parallel to his.

[jelgate]

Thats a creation of an alternate timeline not an alternate universe
