>How more advanced would an alien civilization's knowledge of physics be?
If we´re talking about an alien species here on earth, what´s the likelyhood of them regarding our knowledge of relativity, particle physics and maybe even electro magnetism as child's play?

>What about their knowledge of math?
Could it be that humans are up to date or maybe even already beyond what extraterrestrials consider advanced maths? Maybe aliens won´t even understand abstract mathematics if they somehow manage to understand physics without very complicated arguments or proofs, maybe they would shrug and scratch their heads at the definitions we give for cohomology and more wacky shit like toposes.
