| Mar 26, 2016 at 9:29 | comment | added | Ilya Lapan | A quantum number generator based on collapse of wave function could give you a different number. If your number generator is say based on measurements of spins of electrons, if you go to a point before wave function collapse I think you might get a different result. But this scenario is unrealistic so it's all just speculation. | |

If the number generated depended on the time only (and was not determined by the number of visitors at the web site, this would change because there would be one extra visitor), even then probably not because you would presumably also have to apply the same switch dynamics to the terminal to ensure that the signal to the web site was identical to the original try. | |

| Mar 25, 2016 at 20:18 | comment | added | The Broken Ace | @ACuriousMind Yes, I mean a website like random.org. Yes, I do mean whether the universe is deterministic, but in this case in a simplified version. | |

| Mar 25, 2016 at 20:12 | comment | added | ACuriousMind♦ | Are you trying to ask whether the universe is deterministic? Also, note that "random" numbers are usually pseudo-random. | |
