I was ok with neutron stars, black holes and pulsars on one end. I was even ok with electrons, protons and quarks on the other. The thing I'm having a hard time rapping my head around is this sting theory. Help a old man out will you? I want to understand (believe). Any help will be apperciated.

String theory is one theory that we're probably not going to do a whole show on. The problem is that there just isn't any observational evidence for it. It's just a mathematical model that seems to work nicely.

If you want a good explainer, though, watch Brian Greene's Nova special called the Elegant Universe. You can watch the whole thing online. Here's a link:

I read the book, pretty interesting and enlightening, although i found it vague in its explanations of some really crucial points.
