From someone else's inertial reference frame perspective there are an infinite number of possible ruler sizes, this is no different than me measuring a tree at different angles or at different distances and measuring different tree heights. In special relativity spacetime rotation is due to...

1. There's no such thing as a rigid object think of the propellers as more slinky like at high speeds. 2. No information is being transferred at the speed of light. It's just an illusion of faster than light speed.

Your graphs both look correct, in special relativity a change in the ship's inertial frames will cause a time jump in "earth time", the fact that acceleration caused it is kind of irrelevant it's the change in inertial frame that matters. It results in a path change and a slope greater than 1...

It's a quantum mechanics postulate that the particle is in a super position state. With different probabilities for different positions when observed. This postulate cannot be derived from a set of variables.

Yes it can be negative In the below space-time diagram enter .6 for velocity, 0 for x, 4 for t for event B. You will see a negative x' for event B, x' = -3, t'=5 http://www.trell.org/div/minkowski.html

There's a symmetry here, the measurements are only valid in their own reference frame. If I walk away from you you measure me smaller and I measure you smaller it seems contradictory until you realize the measurements are only valid from their perspective. Likewise in relativity space twin...

"suddenly skips ahead in time" is almost never accepted as a reasonable answer by most people, I suppose you need to introduce the block universe and angled slices idk "Earth-twin's answer to the question "what time does the rocket-twin's wristwatch display right now?" never changes...

Not a different scenario a different point of view, everybody will be traveling exactly in the same way, same speed same distance, just the handoffs of times will be different.With the original twin paradox thought experiment you get the same answer from everyone's perspective.

My diagrams have acceleration in them! He's creating a "ghost being" that is jumping from one ship to the other without accelerating. So he's kind of adding apples with oranges intervals. If you think that's untrue what makes A so different than B and C? Relativity says motion is relative. I...

Okay he doesn't say that but maybe he misspoke. But I could assume C at rest, perform similar SpaceTime interval calculations, and have them record the longest time.

Well that's not true he's saying you start the clocks simultaneously and measure time from that start. (e.g. spaceship C to event 2).

Yes but where/when does the thought experiment start and end in his thought experiment? To compare World lines you need a start and ending event. The twin paradox gives you those two events. He says in the beginning of his thought experiment everyone sets their clock to zero, but they're all...

But that's not the twin paradox thought experiments because they not are together to begin with and they never meet up at the end. They would have to jump for one spaceship to another which is acceleration. In any event to have different velocities they would have to accelerate he just kind of...

oh, ok

I mean it's instantaneous so it has to be discontinuous.
