That’s evidence that it didn’t here, but not an explanation as to why or how.
- pfdietz 3y agoIt could just be dumb luck. Ordinarily we reject hypotheses that require very rare outcomes, but observer selection implies we shouldn't do that.
- mensetmanusman 3y agoThe calculations currently work out that the dumb luck is so incredibly lucky that it doesn't seem feasible to have happened in the observable universe due to the number of zeros involved.
- cvoss 3y agoBut the whole point of the anthropic argument for anything (oxygen, goldilocks earth, fine tuning) is that it doesn't matter how slim the odds are. We cannot observe a universe where the lucky thing doesn't happen because we can't exist in such universe.
- mensetmanusman 3y agoThis is solving the problem by adding infinity more universes, which actually lets you solve anything :)
- pfdietz 3y agoEven our own universe could be vastly larger than the observable portion.
- furyofantares 3y agoThe universe is probably a whole lot larger than the observable universe.
- mensetmanusman 3y agoIs it 10^100* bigger?
- pfdietz 3y agoIf inflation occurred at an early time, it could indeed be vastly larger.
