Particle Physicist Dr. Stephen M. Barr of the Bartol Research Institute gave a lecture at MIT “What’s So Special about the Universe?” on how the universe appears to be teleological, which is to say, that the universe’s laws and structure seem to have a purpose: that human life be possible.
My inadequate summary: The chances of the physical constants of the universe falling within the narrow range necessary to sustain human life are impossibly small. This observation is often called “anthropic coincidences”, and is evidence from within particle physics strongly suggesting that the universe is designed for human life. The counter-suggestion is that there are multiple universes with different physical laws (or that our one universe has multiple “regions” with different physical laws), which means that it might be plausible that our part of the universe with its human-friendly physical laws did arise randomly. But, Prof. Barr argues, the multiverse theory in its most plausible forms doesn’t remove the anthropic coincidences, leaving it still likely that the most fundamental principles of the physical universe are organized so that human life might exist.
I’m the chaplain at MIT, not an MIT scientist. The lecture is without equations, but is at the edge of this non-scientist’s intellectual world. But in my casual survey, the students were blown away, the more so the closer they were to studying astrophysics.
