On The Way
As time passes, I am becoming more and more confused about the fact that many physicists still appear to be quite content to study quantum gravity using an old notion of observable, and their assumption that this should dictate the existence of enormous numbers of particles which have never been observed. And not just a little neutrino (predicted on the basis of conservation of energy) or not just a few quarks (predicted on the basis of lattice patterns), but ridiculous numbers of squishies which are conveniently too massive to have been observed. How can one possibly investigate new physical regimes in a framework so clearly based on guesswork? I just don't get it, and I would really like someone to explain it to me.
