“PHYSICISTS dislike coincidences such as those set out on these pages, suspecting them of covering up some new principle they don’t yet grasp. But when they run out of theories, there’s a one-size-fits-all explanation that can answer everything without really answering much at all: the universe is as it is because we’re here to see it. This piece of circular logic is the anthropic principle. A universe inhospitable to life would have no human beings around to observe it, so the one we see must, by definition, possess features essential to accommodating intelligent life. But that doesn’t tell us whether a slightly different universe might still host life, why our particular universe exists and not some other, or why we see finely balanced features with no bearing on the emergence of life….”

“Uppsala University researchers have devised a new model for the Universe — one that may solve the enigma of dark energy. Their new article, published in Physical Review Letters, proposes a new structural concept, including dark energy, for a universe that rides on an expanding bubble in an additional dimension. We have known for the past 20 years that the Universe is expanding at an ever accelerating rate. The explanation is the “dark energy” that permeates it throughout, pushing it to expand. Understanding the nature of this dark energy is one of the paramount enigmas of fundamental physics….”
