I’m reading Max Tegmark’s newest and only book Our Mathematical Universe, which I will be reviewing for an academic journal. I wanted to share, as much as I could without copyright infringement an amazing point on the issues of fine-tuning in the most broad sense of the word (the existence of a universe that permits the existence of life).
So what are we to make of this fine-tuning? First of all, why can’t we just dismiss it all as a bunch of fluke coincidences? Because the scientific method doesn’t tolerate unexplained coincidences saying, “My theory requires an unexplained coincidence to agree with observation.” For Example, we’ve seen how inflation predicts that space is flat and the spots in the cosmic microwave background should have an average size around a degree, and that the experiments…. confirmed this… Suppose the Planck team observed [something else being] much smaller average spy size, prompting them to announce that they’d ruled out inflation with 99.999% confidence. This would mean that random fluctuations in a flat universe could [author's emphasis] have caused spots to appear as unusually small as they measured, tricking them into an incorrect conclusion, but what with 99.999% probability this wouldn’t happen? In other words, inflation would require a 1 – in – 100,000 unexplained coincidence in order to agree with the measurement…read more »
