i think it "exists" as a mathematical construct, as in the standard model needs it, and the current perception of physics is based on it.But yeah that is basically being constantly rewritten, and it's being contested by an increasing number of people, as like so many things have had to be added to make the standard model work to the point where it's at an absurd complexity. Michio Kaku(spelling????/) keeps on about how he wants to sum the universe up in one simple equation. He's a cool guy, i like him.
I have a neat interest in physics and like when my head goes into overdrive when trying to sleep, it's one of the things i keep thinking about, kinda how everything works. It's all full of neat things and reading about how they can weigh planets based on their vibrations and stuff is amazing. A lot of my music is based around abstract physics stuff, the music of the spheres is so amazing to listen to.
