Episode notes

Two reasons why you're not enthralled by string theory. One is that we should give a lot of credence to the possibility that something like string theory is behind the whole story. The other one is, given what we know about the in partical physics, its just hard to build models with this kind of substaneyes? Could be absolute, but ok, ledme, let's trest tht.

Modern particle physics is a victim of its own success. We have extremely good theories — so good that it’s hard to know exactly how to move beyond them, since they agree with all the experiments. Yet, there are strong indications from theoretical considerations and cosmological data that we need to do better. But the leading contenders, especially supersymmetry, haven’t yet shown up in our experiments, leading some to wonder whether anthropic selection is a better answer. Michael Dine gives us an expert’s survey of the current situation, with pointers to what might come next.
