@Orion: Not at all. Honestly, getting addressed as "Princess" feels quite weird.
@Irish: It's hard to make a direct comparison as haven't been to your world, but from what limited information I've been able to gather, the best way to explain magic would be like this:
I know you have laws of physics and such, so we'll use that as a starting point. Best I can tell, our worlds both share the same basic laws of physics. Such as thermodynamics and the laws of motion. However, your world has
only those laws of physics, whereas our world has (and this is only speaking the most vague of terms) a secondary set of laws of physics which exist independantly of the primary laws. The reason for this difference is that (as far as I can figure) your world has only a singular type of energy (which manifests in different ways of course, but is always subject to the same laws). Over here, we would identify that set of laws as "mundane physics." However, our world has a second type of energy, magic, which has its own laws of physics which exist independantly of the first set of laws. So whereas you simply have "Laws of physics" we have "Laws of Mundane Physics" and "Laws of Magical Physics" which govern two different types of energy, mundane energy (what you're familiar with) and magic energy (which I study). The laws governing these two energies very often don't line up with each other (i.e. some things are possible with mundane physics that magical physics couldn't produce, and vice versa). There is overlap, of course (pegasus magic is a good example), but we haven't yet discovered all the ways that mundane and magical physics interact.
Then you have stuff like the Pinkie Sense, which can't be adequately explained by either branch of physics. We're still not sure what to make of that.
