"So. Spell resistance. I've never heard of anyone getting through ours, but I don't know what's up with your situation and we might want to test mine some more. In general, defense magic - magic that makes things stay as they are - is going to play about as nicely with your weird physics as any of the types of magic I know of do. I should list the types - there's a mnemonic for them that goes, 'someone used structure magic to paint a picture of an orchard and a command mage wanted to destroy it but used knowledge magic to learn it was warded and...' actually, I forgot this was getting translated and there's no reason to expect it to sound catchy to you. The types of magic are structure, illusion, green, command, void, knowledge, defense, force, heat, sun, death, and inheritance. Of these, I think structure is the most unlikely to work normally for you, it's all about the rearrangement of the kinds of atoms we have. - Scratch that, no, sun is going to be worse. Illusion is what it sounds like, and does sounds too. Green encourages plant growth - I don't know if it could directly make you in particular healthier but it wouldn't shock me. And it could be done as an area of effect on an artifact that would make a place friendly to you in particular... seems small-scale for anything you'd need to do once you got through here, though. And I'm not completely sure it would recognize you as a real plant and I'm also not totally sure it wouldn't give you cancer. Which is something I treat! But not in aliens. Anyway.
"Command magic doesn't actually do positive commands, just negative, and it doesn't affect your thoughts directly. Except insofar as 'stop breathing' will keep you from thinking about things and 'don't breathe unless you're doing what I want' might convince some people to do some things. It's useful for criminals and addicts. I don't know if it's something you need or could use. Knowledge magic is for learning things. You could use it to look at the past, including thirty thousand years ago, assuming you could even get a knowledge mage into your universe - I don't think it works across universes or it wouldn't be common knowledge that there are no aliens anywhere. It can't get through illusions but it can reliably distinguish illusions from real things.
"Defense keeps things from changing. Including along axes like 'does it have any spells acting on it right now?' or 'is it within two inches of this other thing?' I think it might be useful for you and I don't know how because I don't know what you might want to protect. Force is... what it sounds like. You move things. With your mind. If you don't already have cheap mass transit, we solve that with this one.
"Heat is... temperature control, and now that I'm thinking about how temperature works I don't know if this one will work for you... Sun, no, skipping that one, it won't work either... Death magic is for killing things. Where I come from, diseases are caused by small living organisms that sort of eat people from the inside, so we use death magic to protect ourselves from that. And inheritance is my kind and I've already told you about it.
"Beyond that, we have - specific physical knowledge that won't help you - we have math that might - we have a system of government I don't know if you have in your world, called a republic, that turns out to be almost immune to civil wars and famines and is comfortable for people who can't defend themselves on their own to live in alongside people who could kill them."
