So, I had an interesting realization the other day. We know that the speed bubbles from bendalloy or cadmium allomancy attach themselves to reference frames, and speed things up or slow them down relative to that reference frame. We know that those reference frames can be ones that experience acceleration: case in point, whenever a bubble attaches itself to the reference frame of the ground, which is rotating about Scadrial's axis and orbiting the sun. And, from the perspective of general relativity, any frame in which there is a gravitational field is really no different from an accelerated frame. We also know, from descriptions of the experiences of characters within speed bubbles, that nothing weird happens in regards to their experiences of gravity. They feel the same weight inside a bubble as they would outside a bubble. When you drop something inside of a speed bubble, it falls to the ground at the rate you would expect to see outside the bubble: it doesn't float in the air or suddenly crash to the ground. (You might call this an extended version of Einstein's equivalence principle: you can't tell whether you are inside a speed bubble by doing measurements on the weights of objects.) All this means that, in order for there to not be any weird effects on the weight of objects inside speed bubbles, is that speed bubbles have to treat inertial forces and gravitational forces the same way, just as we would expect from general relativity. And that means that if Wayne managed to anchor a speed bubble inside a large spinning centrifuge, he could observe the centrifuge slowed down (relative to the rate of time flow within the bubble) while still experiencing the full centrifugal force. If he dropped something inside, it would "fall" towards the outside of the centrifuge, even though the apparent motion of the centrifuge is practically stopped. Does anyone know of any WoBs dealing with speed bubbles in accelerated frames, or in free-fall? Someone needs to ask Brandon what would happen if Wayne burned bendalloy while on a merry-go-round, or while skydiving.
