A Physicist Tries to Avoid the Fact of Design in Our Universe…

Physicist Alexander Vilenkin of Tufts University argues, against apparent fine-tuning, that our universe’s cosmological constant should have a special value like zero, but doesn’t

In his discussion with Robert Lawrence Kuhn at Closer to Truth, Tufts physicist and cosmologist Alexander Vilenkin addresses the question, “Is the Universe Fine-Tuned for Life and Mind?”: If the deep laws of the universe had been ever so slightly different human beings wouldn’t, and couldn’t, exist. All explanations of this exquisite fine-tuning, obvious and not-so-obvious, have problems or complexities. Natural or supernatural, that is the question. Vilenkin — who is also a professor of evolutionary science — concedes the main point: Alexander Vilenkin: [0:40] Well yeah that’s right. It appears that the Universe is fine-tuned in the sense that there are about 30 constants of nature which take some specific value: if you look at these numbers, they look Read More ›
