Space Born Era Mistborn

[CosmereAvair]

Haven't finished reading the bands of morning series just yet, but I had a theory on how you could space travel with the magic systems on Scandrail. All you would have to do is have a really strong steel push that would launch the ship into the air. then when the ship launches into the air Cadmium burners stop the ships time, allowing the planet to continue its rotation of the sun, while the spaceship stay in place. this wouldn't require the ship to have force to pierce the atmosphere just enough to get off the ground. Once it goes off planet due to newtons law of physics how to move the ship is anyone's guess. But I thought that would be the best way to get a ship of planet.

I think a lot of the technology progressions in Mistborn will end up mirroring what has happened on earth (and beyond if planet traveling becomes a thing). Harmony makes a comment in one of the books about how he fears the people of Scadrial are becoming complacent because their technological advancements aren't as far along as they should be. Since you haven't read all of the newest books, I won't spoil too much. You have some cool ideas, but I think what we'll probably end up seeing is that Scadrial will undergo the natural evolution of a technological society as the years go by...an evolution enhanced by Allomancy of course.

Gravity is still A Thing inside speed bubbles so your ship would go up with the Steelpush, then the speed bubble would go up, then the ship would crash very quickly from the perspective of those inside it. Let's see, 9.8m/s^2 times whatever the multiplier is for the Cadmium bubble, divided by the square root of Hoid's favorite number... And that's assuming you could get a large enough bubble to begin with to completely enclose your ship, and the allomancers doing it were skilled enough to set up a bubble capable of moving with them. Brandon has said that sort of thing is theoretically possible but difficult. Otherwise you'd have a very short-lived bubble as parts of the ship fell out of it, briefly started moving at very different speeds and caused the entire bubble to collapse. Then crash even more spectacularly. It's a nice bit of lateral thinking but it wouldn't work.

I guess my theory was as effective as a speed bubble and a slow bubble!

An interesting thought. It relies on some unknown interactions regarding how frames of reference work, though. If, for instance, you could finagle it so that your cadmium bubble shares say the moon's some random asteroids frame of reference once it's created, then I could see a scenario where the bubble (I believe this would work with either time of time bubble) would be yanked off in the direction of that object and pull the ship along for the ride. That'd be quite a feat of finagling, though.

I'm not 100% sure gravity is completely a thing for time bubbles, or at least that it's not scaled to match the bubbles compression rate. So if you had a 1/10 cadmium bubble then I could see the objects within falling at ~1m/s^2. Also recall that time bubble occupancy is a completely on/off thing: there's no such thing as "parts" of the ship being not affected by the bubble. If that were the case than calculus would take over and everything would explode.

Ahh, I had to reread the exact text of that scene with a cadmium bubble from Bands of Mourning, I'd forgotten exactly how they explained what went on there. Very nice read, that thread.

As for gravity, we know it acts normally from the perspective of anyone inside a bubble (either type) when it's established on the ground, or someone would have commented on the wonkiness in three books. Assuming this holds true for bubbles set up in midair, you may appear to fall slower from the perspective of an outside observer but from your perspective inside the bubble you'd still be falling at the same rate as normal and when you hit, you'd go splat.
