Go back and use my formula to compute odometer distance between traveling inertially between two constant position world lines in an...

Correct, as long as the entry and exit speed is small. My formula builds in length contraction, so if entry and exit are done very fast...

Right. Entering and leaving the bubble you would measure the rate of eulerian observers going past. Note that my definition is...

But you said exactly this in your last post, just above!

I believe I have clearly expressed the problem I see with this multiple times. Again, you want sum a bunch of measurements made by...

Not what I meant. An odometer measures passing road. The road is defined by a chosen timelike congruence. If I close the eulerian...

Ok so this means that distance from a bubble center observer to a world line just to right of the whole bubble region, per fig. 3...

Just to be clear, the time inside shell of matter is slower than outside far away, even though both are flat. That is the typical case...

No we are in agreement that the peculiar velocity is c. The difference is the notion of distance traveled. You have not provided any...

So, then, it is obvious that for a traveler in the center of the bubble, using Eulerian observers to define a road, the odometer...

Those light cones are, indeed off, but only that the right bound of the cones can approach horizontal, but never reach it. That is a...

An observation is that if you take the limit as peculiar velocity goes to c, of comoving odometer distance as i defined in my prior...

Getting back to the notion of distance, and how to make sense of it in relation to the warp drive metric, a few common conventions in GR...

And this is an expectation which is false for almost any type of bubble or shell you can construct, where inside and far away are both...

It relates exactly to what you said. You said it was intuitive that proper time inside the bubble was the same as outside because both...
