- Does the universe have a destiny? Physicist Paul Davies thinks so and that quantum mechanics allows the cosmos' future to influence the past -- explaining the origin of life. http://www.fqxi.org/community/articles/display/136 62 comments science

- Newtonian gravity shown to emerge from loop quantum gravity for first time, thanks to new model in which gravity is result of entropy, not a fundamental force of nature. http://www.fqxi.org/community/articles/display/132 95 comments space

- Time is an illusion? Not according to new model of a Crystallizing Universe which explains how time flows and why the past is set while the future remains open. Model rescues free will and explains how weird quantum experiments in which photons appear to "time travel". http://www.fqxi.org/community/articles/display/131 122 comments science

- Time doesn't exist and the universe isn't really expanding, says physicist Julian Barbour. Both are illusions. Discarding both could lead to a theory of quantum gravity, in the spirit of Einstein's General Relativity. http://www.fqxi.org/community/articles/display/117 358 comments science
