Maybe some sort of way to lower the rest mass of matter.
Now that you mention it, what if we can create a region of space in which c is greater than normal? Is that possible? Would living things be able to continue living inside it?
Even if so, it doesn’t matter how you do it, moving faster than c does bad things to causality. You’d be one Lorentz boost away from a grandfather’s paradox. I think that would hold for a region of space with lowerc too, weirdly enough, because it itself could also be boosted in a way discordant with everything else.
You could just abandon relativity entirely, I guess, but that’s kind of a key ingredient in how the universe works. Making a theory like that, I’d imagine, is like baking chocolate chip cookies without the chips.

Like some sort of… sub-space?
