Ask Slashdot: What Are the Implications of Finding the Higgs Boson?

Full disclosure: I'm a physicist with some high energy/field theory in my background; but I stopped doing anything with high energy theory twenty years ago. Maybe someone who works in the field will disagree with me. And also, some of what I'm saying here I said on/. nine years ago, when someone asked what the practical implications were of experiments that were shedding light on the quark-gluon plasma, because my answer is close to the same.

With that said . ..I can't imagine any short (or even medium) term practical application. In fact, I can't even imagine practical value in the long term. Mind, it's certainly possible that down the road someone cleverer than I am will come up with something. In fact, that's the normal way in which major technological advances have occurred. For instance, Schottky wasn't trying to invent the transistor when he started studying the quantum behavior of transition metals. Michael Faraday didn't really see any public benefit to understanding electromagnetism, either. It's always worked like this: pure research has historically been without such obvious benefit.

But nevertheless, I don't want to suggest that that's the eventual result here, because I don't believe it will be. I think that would be disingenuous of me. I highly doubt that an improved understanding of Higgs physics will ever produce any wonderful and amazing technological advance. To me, the motivation is simply that understanding and knowledge -- especially of something like how the Universe got to be the way it is, and why it works the way it does -- is inherently a good thing. It has value by definition. Perhaps my least favorite thing about our society is that we are trained to evaluate the worth of things in terms of their economic value. Just like love, understanding has its own value, in my mind -- bereft of any "practical" value.

Let me give you an example of what I mean. To the best of our ability to tell, there's only one place where elements heavier than carbon (such as nitrogen, oxygen, sodium, etc. etc.) can be formed in large amounts -- and that's inside a star. Only elements as heavy as carbon or lighter can be formed in the early universe (and, for that matter, the amounts of Li, Be, B and C formed in Big Bang Nucleosynthesis are very very small); for heavier elements, and for larger amounts of carbon etc., you need a star. Now, if you didn't already know this, stop and think about it for a second. A huge chunk of you, perhaps all of you, was inside a star at one time. It appears that you and I are star debris. And it gets even better. The way that large amounts of these elements, forged within a star, can get out of the star is if the star supernovas -- dies at the end of its lifetime with a big boom. That big boom also serves to make very heavy elements -- such as uranium, for instance -- that cannot be made even in a star while it's burning away. There's uranium, and other similar very heavy elements, on our planet. Do you see what I'm getting at? Much of the atoms that make all of us up, that make this planet up, were at one time inside a star (or stars) that lived its life, supernovaed, and spewed out debris. Eventually, maybe a few hundred million years later, that stuff is part of our planet, part of our atmosphere, our water, part of you and me. We are all brothers and sisters; we all came from the same place, sorta.

Now, that knowledge will never make me any money. It will never have any practical benefit in my life. And yet, I consider myself immensely richer for knowing it.

Understanding has its own value.
