I have a funny mental framework when I do physics. I create an imaginary audience in my head to explain things to - it is part of the way I think. For me, teaching and explaining, even to my imaginary audience, is part of the process.

Space can vibrate, space can fluctuate, space can be quantum mechanical, but what the devil is it? And, you know, everybody has their own idea about what it is, but there's no coherent final consensus on why there is space.

I'm doing physics because I'm curious about how it works - full speed ahead, damn the torpedoes, don't worry about whether somebody is going to be able to do an experiment next week, just figure it out.
