Well, would it be possible to create a breeding program for the purpose of breeding Mistborns or full Feruchemists in AoL era?

I thought this confirms that Ati was the original Vessel. Hoid speaks with familiarity about Ati, which suggests he knew him beforehand. I can't see how else Hoid would have known him so well. Also, he bunched him with Rayse, which probably means the recipient (Frost I believe) knew them both as well. Unless there is some information I am missing?

Wow, big post indeed... Infact, it covers most (if not all) of my theory. I agree, it probably wouldn't be a 2:1 ratio, but I also think its unlikely that they would be able to pop up that many Bendalloy bubbles, as you said in the disclaimer. Also, we don't really know how large the cosmere is, so even FTL travel could take a while (years maybe?). Cadmium would be most useful there. I think that Cadmium and Bendalloy most likely have the same factor of change, because they cancel out. So B speeds up time by 8, but C reduces it by the same factor, meaning time is at normal levels. Unless the cancelling out effect is due to something else like investiture interference. As for size, WoB says that size can actually be manipulated, but it doesn't correlate with strength. To what extent though, is anyone's guess.

I'm certain Ettmetal is used in some form or another to propel the spaceships. Maybe in its explosive form, or maybe used in a primer engine. We'll probably get more information in Era 3, where they have probably developed early spaceflight technology. Since time warps so significantly in a speed bubble (factor of 8 apparently), you wouldn't even need to go that fast (relatively speaking) to go FTL. Apparently, the coppermind says that Bendalloy bubbles compound. So Scadrians could just throw up multiple bubbles to make the space ship faster, while also compounding Cadmium bubbles to make time pass even slower for the crew. There would need to be more Cadmium bubbles than Bendalloy, as they still cancel out.

So we all know that Mistborn Era 4 Scadrial has become a space faring civilisation, and that in Sixth of the Dusk, there is at least one civilisation that has reached this status. Given the sheer versatility of the investiture systems, it is pretty likely that the aliens are in fact Scadrians. That opens up so many questions, but I would like to focus on one specifically: how did they do it? As mentioned before, it is Scadrials magic systems which probably made them the first space civilisation. I believe that it is a combination of Cadmium, Bendalloy, Ettmetal, and Medallions which have allowed them to enter the space frontier. Bendalloy makes speed bubbles, so if you attach one to a spaceship, the math on the wiki page says you would compress 2 minutes of the ship moving at full speed into 15 seconds of actual travel time. The problem with this is that people inside the spaceship will still age, as it is time which is being manipulated. That means that while the spaceship would travel FTL relative to the cosmere, inside the bubble, people would age normally. Essentially, it unpractical space travel and very limited. BUT, if you also create a smaller cadmium bubble around the structure of the ship ( a C.bubble within a B.bubble), we know from this WoB that the effects will cancel out: This means that the crew wouldn't be trapped inside the speed speed bubble, and so will experience time normally. However, to make this technology even more efficient, the Scadrians would put up ANOTHER cadmium bubble within the first cadmium bubble (C.bubble within C.bubble within B.bubble). This would allow them to travel FTL and not feel the time effects at all! Essentially, they would be able to get anywhere in no time. I do believe that Ettmetal will be used in the propulsion of the spacecraft, probably through some nuclear propulsion technology. This is what would take the spacecraft to such high speeds. I don't really know how to explain all the other uses, so here's @hwiles comment pulled from here: As for the medallions their benefits are endless: from breath, to healing, to warmth, to weight (which will probably be useful combined with pushing and pulling in space) and the various other technological impacts. NOTE: I just found out from the coppermind that time bubbles in fact compound if used together. This is crazy, and makes FTL travel much, much easier. A normal speed bubble speeds up time by a factor of 8. Compound this with 10 bubbles and you would be travelling insanely fast. WoB is unclear to me, not sure if will double (8x2) or multiply (8x8). We have no information on Cadmiums factor of change, but we can assume that it will be the same as they cancel, and that it'll also compound. Basically, you can use primer cubes each powered by Bendalloy and Cadmium, structured in specific layers. All the Bendalloy bubbles would need to be outside, and you would need about double the amount of Cadmium bubbles to counteract the Bendalloy bubbles and still create their own time-slowing bubbles. What do you guys think? Any other technology which would make FTL travel feasible or easier for Scadrians? (This is my first theory, so there might be gaps in knowledge. Feel free to point them out).

Great! Thanks for your input. I guess having 3 bubbles would make more sense. As for fuel, I would presume that in Era 4, they would have discovered a way of mass refinement and extraction of most metal, similar to how Aluminium was rare on Earth until electrolysis was developed in the 19th (20th?) century. That would make all metals much more abundant.

Well... What if you create a larger bendalloy bubble around the space ship and a smaller cadmium bubble around the crew members? Theory of Relativity says that, as long as you are in an inertial frame of reference, you cannot determine what you're actually travelling at (very crude but I'm not in the mood to explain it lol). Thus, the crew members won't feel the effects of the bendalloy bubble, as the cadmium bubble is what takes preference. Now that I think of it, I'm certain Mistborn Era 4 (and Sixth of the Dusk) spaceships are a combination of Bendalloy, Cadmium, Medallions and Ettmetal. I think I'll start a new thread for this, unless someone can confirm I'm really, really wrong lol.

Ahhh ok, that makes sense. I guess that just was an aspect I didn't consider. Thanks for clearing it up.

But all the Shards witnessed Adonalsiums shattering, so wouldn't they all already have knowledge on that? I can understand that they probably didn't have the complete knowledge, and Odium probably experimented to perfect his technique, but surely they would have known of the possibility and the risks involved? So how did Odium manage to Splinter 4 Shards?

So, essentially, from this WoB, we can determine that the method of Splintering is the same as the original Shattering, and that this will hold true across all levels further down the line too. What I want to know is if the original 16 Shardholders were all present with Hoid at the EXACT moment of Adonalsiums shattering. If so, then wouldn't they all technically know how to splinter/shatter other Shards? From the information we have, so far the only Shards who have demonstrated knowledge of Splintering are Odium and Autonomy (their misendeavours on Sel). Why would this be the case? Extra question: Which non-Shards, that we are aware of, have knowledge of Splintering? Hoid is an obvious pick, but what about Khriss or other 17th Sharders?
