In the Marvel Cinematic Universe, magic and science are said to be one and the same.
In Iron Man 3 the Earth scientist Maya Hansen created and weaponized Extremis, which made people inhumanly strong, nearly indestructible, and gave them the power of extreme heat, at the risk of burning out of control and destroying themselves.
In Thor 2, we learned that the Dark Elves had an ancient magic known as the Kurse, which made them incredibly strong, nearly indestructible, and appeared to have a burning effect, at the price of certain death when the power burned out of control and consumed them several hours later.
Essentially, Maya Hansen’s Extremis is an isolated development of technology that the Dark Elves had created thousands of years in the past.
Does this mean that Maya Hansen would, in effect, be recognized on other planets as a sorceress? I’m gonna go with yes, because that is just incredibly cool.
