Maeglin,
This could turn into a major hijack, so, I say, if you wish to persue it, I’ll gladly participate in another thread. It pains me too much to see the highest echelons of the academy involved in such nonsense to do much more than be bitter about it. I’ll say this, and no more:
That article wasn’t nearly harsh enough. As for the cosmological constant, Einstein indeed made a mistake, because at the time he fudged the constant to force the universe to fit a preconceived and evidentially-shakey notion of how it ought to behave. His theory, as it was, predicted another picture entirely, and evidence demonstrated he was doing fine before he succumbed to prejudice.
As it stands presently (and Einstein couldn’t really have known), his fix for the perceived problem, while lacking a good rationale at the time, was a logical necessity, for no less than the fact there was no good reason to exclude a cosmological constant. In an almost eerie fashion, physicists have shown that relativistic quantum field theory necessitates a cosmological constant by predicting that even a vacuum has energy. It reminds me of something Murray Gell-Mann said: “Whatever isn’t forbidden is required!” The trouble is, without some mechanism that exactly cancels out this vacuum energy, current quantum theory is off by a minimum value of about 10[sup]60[/sup]. IOW, present quantum theory predicts the universe would blow every point in space apart to infinite extent almost instantaneously after a Big Bang, and not even atoms would have time to coalesce. That’s about the biggest predictive failure scientists have ever worked so hard to produce. Worse, it’s almost certain now (based on excellent astronomical observation) that there is a cosmological constant, having a magnitude (especially compared to the predicted value) of relatively-close-to-but-not-quite zero. There is no good explanation for this. Either there should be zero net vacuum energy, current theory tells us, or an amount so fantastically, absurdly huge that prediction bears absolutely no resemblance to the universe we observe. It’s the worst problem of “fine-tuning” in physics.
I’d say the greatest source of Hope for folks at places like the Discovery Institute that scientists will be forced by sheer weight of reason to consider the idea that the universe was created, yea, designed for humanity to inhabit.
Thus far, String Theorists have apparently painted themselves into a corner such that the only good “prediction” of the universe’s properties they can come up with requires a pernicious form of the anthropic principle, but soften the theistic or deistic potential of this revelation by “predicting” the existence of, at least, 10[sup]500[/500] vacua, one of which we inhabit, none of the others which might even, in principle, be subject to evidential scrutiny. They call this picture “The Landscape”. I call this “pernicious” because, as I alluded to two sentences ago, getting the evidence of extra dimensions String Theory absolutely relies upon could require energies quite simply unattainable by mortals. Some String theorists, in the face of this, are even starting to claim that at least some scientific theories (maybe only theirs) needn’t be falsifiable. I didn’t make that up. I see such madness not so much as a problem of philosphy as one of definition; i.e. if something isn’t falsifiable, how in the Hell can you call it science? Perhaps inadvertantly, IMO, they’re doing the Discovery Institute’s dirty work for them.
