What's being discussed here can't be stated accurately in anything but the language of mathematics. However, physicists toss out a hypothesis and see it shot down by peer review (that's the way it's supposed to work). Then, based upon the rubble of previous thought*, new data suggests new approaches and things.

Me, I don't know yet. I would very much like to go out there and poke around and find out.


*Not all "old thought" is wrong. Newton's gravitation works well in the macro universe but fails in the quantum physics. Izzy was right and wrong; physicists, at least the good ones, recognize that.
