After I wrote last time on the odds for cosmic inflation, I started noticing a flurry of comments on an older post about alternatives to the big bang. So, might as well go back to the basics, and ask what the odds are that the Big Bang is correct! That the Big Bang got it right, to an unbelievable, indisputable precision! Then go learn about inflation , which can cause the Big Bang. A variable speed of light cosmology might hold some promise, but it isn't clear those models don't also require a Big Bang!
