Islington Posted September 7, 2015 Report Share Posted September 7, 2015 So I've seen people talking about Bendalloy/Cadmium FTL travel. I am apparently a big stupid moron, because said posts sound like Greek theoretical physics instead of regular theoretical imaginary magical physics. Could someone explain it like I'm five? 6 Link to comment Share on other sites More sharing options...

king of nowhere Posted September 7, 2015 Report Share Posted September 7, 2015 actually, they are speculation. brandon said that alllomancy enhables ftl travel, but we still have no idea how it's done. Link to comment Share on other sites More sharing options...
amulligan99 Posted September 7, 2015 Report Share Posted September 7, 2015 The way i understand the theories is that the bendalloy bubble covers the ship to make it go faster than light. Then a cadmium bubble is used on a room to make the trip only last a few hours to the travelers. Now in order for it to work the bubbles need to constantly be collapsing and being put back up again to keep up with the ship. Link to comment Share on other sites More sharing options...

DSC01 Posted September 25, 2015 Report Share Posted September 25, 2015 (edited) Problem: Pulser speed bubbles and Slider speed bubbles cancel each other out. Also, in this scenario, the Pulser bubble needs to be smaller, but it's actually larger then a Slider bubble. Maybe duralumin can come into play, if there's a Mistborn (otherwise, a nicrosil Misting could help). I don't see how the bubbles could be big enough work, though. If they could be, and the Scadrians are wrong about the bendalloy/cadmium cancellation effect, then you would need a bunch of Twinborn. Their feruchemical ability would have to be zinc because they'd have to be really sharp to be able to fire off their bubbles at exactly the right time to keep the ship in a bubble constantly. A full Mistborn/Feruchemist could probably do all of that, though. Just compound a bunch of breath, food, water, and warmth, and throw themselves through space with no ship.

natc Posted September 25, 2015 Report Share Posted September 25, 2015 They'd run out of metalminds to burn before they reach anything, out in a vacuum like that. I don't see how the bubble cancellation is an issue when we are just trying to get the vehicle to defy relativity, and the people inside certainly don't want to experience quite that much time. You want the ship to be moving ridiculously fast from the perspective of the passengers as well, or they'd be awake for some millennia or so, and that's not happening. Nullifying the dilation would actually make sense, if not for the fact that we need to solve the problem of the g forces you'd get past the light barrier.

DSC01 Posted September 25, 2015 Report Share Posted September 25, 2015 So, you'd have to have a cadmium bubble inside of a bendalloy bubble, right? How would you propose doing that? Spike a Slider with bendalloy? Link to comment Share on other sites More sharing options...
Zathoth Posted September 25, 2015 Report Share Posted September 25, 2015 They would only need the cadmium bubble really. 1. Accelerate to somewhere very close to the speed of light 2. Burn cadmium 3. Let the ship pass through the edge of the bubble 4. FTL The ship is going to speed up once it gets back into normal time because it is slower in cadmium time.

DSC01 Posted September 25, 2015 Report Share Posted September 25, 2015 So, are we assuming the bubble will stay stable on the ship, even as the ship moves? An allomancer can't move their bubble with them, but it does stay in place relative to the movement of the planet. Link to comment Share on other sites More sharing options...

An allomancer can't move their bubble with them, but it does stay in place relative to the movement of the planet. It's a oddly think if you think about. The bubble is actually moving together with the planet therefore is not still. Maybe it is just anchored to the surronding (maybe it's not the better words), Link to comment Share on other sites More sharing options...
natc Posted September 25, 2015 Report Share Posted September 25, 2015 The anchor is spiritually connected to Scadrial like gravitational acceleration is, IIRC, and presumably it should be possible to decouple it and point it elsewhere somehow. Not that anybody probably knows how. Link to comment Share on other sites More sharing options...

Not that anybody probably knows how.But wasn't it actualy based on nearby cognitive aspects? Like, asking everything the bubble intersects with when it is created for an anchor? And choosing whatever created it as a last resource?If it works as I said, you would only need to leave the atmosphere to have your bubbles centered on the ship. No real trick to it, only somehow discovering how time bubbles work when suspended in a vacuum.

DSC01 Posted September 25, 2015 Report Share Posted September 25, 2015 I don't think it's anchored to Scadrial. Powers are bound to a specific place on Sel, but that's just the effect of Dominion. It shouldn't be like that anywhere else. Link to comment Share on other sites More sharing options...
amulligan99 Posted September 25, 2015 Report Share Posted September 25, 2015 There would be no need for allomancers if you use what sourthen scadrial Has which is a tech based allomancey rather than a biology based allomancy. Besides it doesn't matter of you can get the bubbles to move with you all that needs to happen is for the bubbles to constantly be collapsing and being poor up again simultaneously.

It shouldn't be like that anywhere else. Why would it not though? There's no evidence against it, really. You can move everything inside a bubble from people to bullets to trains, but it doesn't get pulled out of the planet no matter what. The very fact that metal is the basis of magic here is entirely due to Scadrial, and if the shards picked a different spot in the galaxy we'd probably have something completely different. Location always matters in the way magic systems are constructed, Sel just has the weirdness of usage being tied to location as well. Link to comment Share on other sites More sharing options...
Voidus Posted September 26, 2015 Report Share Posted September 26, 2015 We apparently don't have all the clues necessary to figure FTL out yet, there's some basic theories and almost all of them have to do with time bubbles but yeah, not enough information yet.

It shouldn't be like that anywhere else. Dominion is not the reason that the powers are bound to a specific place on Sel, as we know from this WoB: Q: I assumed the shard Dominion was the reason why magic's are geographically and/or geopolitically based. Is there a different, essentially unrelated reason? A: Yes, there is a different reason. 1 Link to comment Share on other sites More sharing options...

Mine actually has to do with iron compounding, steelpushing, ironpulling and chains of nicrobursts. Haven't worked out the details yet though, time bubbles might become involved at some point.

And Time bubbles, if nothing else, would work for making sure that the crew is still alive once the destination is reached. Link to comment Share on other sites More sharing options...

Since I'm not an astrophysicist, could you explain why not? (And since I'm not a physicist at all, could you explain it like I'm five? ) Link to comment Share on other sites More sharing options...

(And since I'm not a physicist at all, could you explain it like I'm five? ) Well it would generate potentially a lot of force but the thing about FTL is that it's impossible to achieve just exerting a force, any object with mass can't reach the speed of light, the closer you get to the speed of light the more force it takes to accelerate and it'd take an infinite amount just to reach it.

Eagle of the Forest Path Posted October 16, 2015 Report Share Posted October 16, 2015 (edited) Very clear and concise, thank you Voidus. Edit: So I've been reading some of the FTL threads here too, and I'm wondering. If you put a pulser and a slider with equal-sized bubbles in a space-ship going at a decent clip (possibly with my previous mechanism) and they simultaneously raise their bubbles so they don't overlap completely. The slow-bubble is in front of the ship, the speed-bubble is behind the ship and the ship itself is in the area where they cancel each other out. Could that be an Alcubierre drive? (Alcumancy?) Contracting space by expanding time sort of thing? (maybe reverse the bubble positions, like I said, not a physicist) Edited October 16, 2015 by EagleOfTheForestPath Link to comment Share on other sites More sharing options...
hanago9 Posted October 16, 2015 Report Share Posted October 16, 2015 I created a user account so I could post in this thread I think there's a lot of value to considering the spacial distortion at a time bubble's edge! We know that object that cross that boundary change have their trajectory affected (which is why you can't accurately shoot out of a time bubble, your aim gets thrown off). This reminds me of light bending as it enters water. Also, I really want to re-read the last chapter of AoL, when Wax shoots his own bullet to change it's course. When I first read it, I pictured Robin Hood shooting his own arrow (that happened in the disney cartoon i think?). However, I think there's something important there about projectile physics. Specifically, how did the second bullet catch up to the first one? AFAIK, Robin was able to do it because the arrow's original trajectory was vertical (his first shot was high). Bullets leaving a gun barrel should have the same velocity and therefore shouldn't be able to catch up. Link to comment Share on other sites More sharing options...
