What's really spooky is thinking about the things which we would have been able to observe if we had been around much earlier. Perhaps seeming constants have changed over the history of the universe, or other universes which drifted away from us along now-imperceptible dimensions. (I'm guessing you saw the same Brian Greene TED talk I did.)
- stan_rogers 15y agoLawrence Krauss's longer talk in Toronto†[1] has a better explanation of the "privileged time" idea (and doesn't invoke string theory except to poke a bit of fun at it).

[Edit: I misremembered the location of the talk. Most of the physics talks on Big Ideas are from the Perimeter Institute; Krauss's wasn't.]
