“This is a book written by two cosmologists, Luke Barnes and Geraint Lewis, and published in 2016…This book lays out the contemporary evidence for what we call cosmological fine-tuning – the idea that at least in our current best theories for life to be possible at all, certain numbers in physics had to fall within a certain narrow range. The example that has baffled physicists the most has to do with the cosmological constant. This is the number that measures the acceleration of the universe. In 1998, we discovered that the universe is not only expanding, it’s also accelerating in its expansion. Physicists postulate a force that’s pushing the universe apart, which we call dark energy, and the number that measures that force is called the cosmological constant. If that force was a little bit stronger, everything would have been pushed apart so quickly that no two particles would have ever met, so we wouldn’t have had stars, planets, any structural complexity, and therefore, no life, presumably. If it had been a little bit weaker, it would have increased gravity, and everything would have collapsed in the first split second.” Read more...
