It would appear to me that there's not really an "at rest" state in terms of movement in space. We're on a planet orbiting a sun that orbits the central point of our galaxy, which in turn is also moving and perhaps orbiting something else even bigger. So, "at rest" is always subjective.
Correct, that's classical relativity, from before the notion of spacetime even existed.
But the twin paradox says if a twin travels away at a high speed then returns, they would have aged less.
It depends on who does the acceleration. Acceleration is key for the twin experiment, and the reason it works is because they are the one accelerating and decelerating. This requires "general" relativity to make sense, it can't be explained by merely special relativity.
Whatever is influencing us, there must be a 3d vector in space we, as a whole, are moving toward (probably constantly changing though). So, surely if you sent someone in the opposite of that vector, time for them would actually speed up rather than slow down.
I don't get what you mean here... which 3d vector are you referring to, and why should it exist? One of the important concept is that every reference frame is equally valid.
Would they not "catch up" and be on part overall with time passing?
From one pov the earth sped up, instead of the twin's spaceship slowing down. These are both valid interpretations. You can always catch up by doing the opposite of what you did before, but you need to look at acceleration for it to make sense. Acceleration is what turns your 4d vector so your reference frame changes, and you can sort of arbitrarily change "passing of time" if you can induce unlimited acceleration.
We wouldn't see this skew on satellites and the like because they're travelling with us on that vector but at a constant speed relative to us too. But sending away from us and back, we probably would.
I feel like you're rediscovering the idea of an "aether" which was disproven by Lorentz and Einstein.
Note that I'm not a physicist, just someone who loves staying up to date with modern physics!
Einstein showed that time is not a separate space, but is actually the same as any other dimension. However, we have not found any way to reverse our direction so far. We can only choose a direction to move forward in. In fact, you're doing so when you get in a car; you're experiencing a minor change in how you're moving through time relative to those around you.
Since the set of all remaining time only shrinks, the possibility of anything ever happening at least once in all time should also shrink unless it already happened.
And things happening at a rate per second doesn't mean it increases either if it hasn't happened yet. The probability of me being eaten by a dinosaur today is definitely not higher compared to being eaten by a dinosaur yesterday.
I never said I didn't want it to get popular, I just think there's no point in trying to spread the word about its existence... because the problem is not in people knowing about its existence. The problem is that most average phone users will not find it worth the effort to switch to LOS, with the risks that come with it (banking apps not working half the time, upgrades sometimes needing a data wipe).
Lineage has been the go-to ROM that beat every other ROM in active users by one or more orders of magnitude since the beginning of Android. Everyone that cares a little bit about custom ROMs knows what Lineage is, and if they don't they will recognize its previous name CyanogenMod.
Average users are never going to care about custom ROMs because it's not worth the effort for them, so why would you care about making LOS more mainstream?
