I believe magick is apart of us, there for it is physical on some level just like air. You can feel it and some can see it. As for science, it depends on what you see has science. That's rather debatable.
A random add on: There is a camera that can take pictures of your aura. There was one at the New Age festival where I live last year. Its not just the heat coming off of you, as the colors can be green, blue and red all at once. Could we measure aura's? Count them as physical and real? Though some scientist insist they aren't.
