I know this is a pretty late comment to the party but after going back and playing TES again i've noticed things that blend sci-fi and fantasy so hard it seems to be something new.
Like iamLEAM stated above, their faith is their science. But more than that the way it is presented it seems that their magic is their science as well. Scientists do experiments and research to find out why things happen. In TES wizards do this all the time. Thinking of Mass Effect, the things that happen there are readily accepted because of technobabble and handwaves. And the handwavium is Eezo, as another user said of we were to find such an element we could reasonably do the same things. Well, to the residents of Nirn, Magicka is such an element. It just happens to be infused into every being so they have the inate ability manipulate it, mind of like the Asari dont you think? Perhaps Magicka can alter the state of the basest perticle of existence itself which would explain the fact it can practically do anything. Speaking of Nirn, it was created by the fusion of what was once the solar system into one planet. The different races were actually all aliens to each other. Noted in a book is the story of a wizard who traveled to all the planes of Oblivion, each one created and ruled by a Deadric Prince. In the game Redgaurd it was observed that the planes of oblivion appeared as other planets in the solar system, also we know that every one of the Aedra(nine devines) sacrificed their corporeal forms to form the other planets. In Oblivion itself the oblivion gates were possibly just stargates to the planet created by Mehrunes Dagon. In line with our actual physics is the law of conservation of energy, the Deadra cannot die as stated in a book their souls simply return to oblivion and they reform. I don't know if this makes any sense or whether these thing were already dealt with i was just trying to point out some interesting facts that made me look at the series in a new light.
