Well, no, a designer is a non-starter, for the reasons I laid out previously, so we need a large number of trials if the conditions for life are unlikely.
A large number of trials with different physical parameters is an expected consequence of inflation + high energy physics.
Yeah, I don't think you read what I wrote. Please try again.
What? That makes no sense. Nobody is suggesting that this narrow range of parameters is somehow "special", only that even if other ranges of the parameter space exist, it would be impossible for anybody to observe them.
You mean "expected" as like things String Theory "expects"? Anything observational backing this up?
From the wiki on inflation:
andAt present, however, whilst inflation is understood principally by its detailed predictions of the initial conditions for the hot early universe, the particle physics is largely ad hoc modelling.
oh, and Susskind specifically refers to the parameters of our universe as "special". Penrose does the same. I'll show you videos if you don't believe me.One of the most severe challenges for inflation arises from the need for fine tuning in inflationary theories. In new inflation, the slow-roll conditions must be satisfied for inflation to occur. The slow-roll conditions say that the inflaton potential must be flat (compared to the large vacuum energy) and that the inflaton particles must have a small mass. In order for the new inflation theory of Linde, Albrecht and Steinhardt to be successful, therefore, it seemed that the universe must have a scalar field with an especially flat potential and special initial conditions.
