2 Krasnikov Tube Causality Violations Options

[Irysa]

I have recently read this wikipedia article on Krasnikov tubes, and I am cannot figure out how two tubes creates a violation in Causality.

The astronaughts go in one, appear instantly at Deneb, and then go to the other and appear instantly back at Earth. I don't see any time violations...because even if they didn't have to take time to go from one tube to the other they'd just reappear instantly as if they went no where at all.

Can someone who gets it explain it to me?

When you create the tube, it takes a long time to get to your destination. When you go back, you go back to the origin only a short time after you left, no matter how long you took to get to the destination.

When you create two tubes, one forward (to point B), and one back to point A, you take twice as long to travel. But when you snap back twice, it returns you to point B only a short time after you left, and then to point A a short time after you left the first time (plus the time difference of point B). So, at point A, you start at the present, then go to the future, then go back to the present.

I don't see why you would need to know this, though.

I "think" I understand.

So, you lay the first tube going to Deneb, and make a second one that comes back. If you go backwards to Deneb, they're in the past, and if they go through the tube to earth, they're back even further in the past?

I've been taking an interest in breaking Light Speed lately.

Well, the concept of time at Deneb is relative to your previous encounter there. So it's not really in the past or future. It's that when you go back to Earth the second time, you're there a bunch of years before you went back the first time. Deneb has nothing to do with the paradox, other than being a waypoint.
