People talk about God-given rights. They then insist that a bunch of rights are God-given. I tend to not find their arguments persuasive, but the Universe does seem to protect our right to not have our historical timeline messed with.
Even more possible (though totally not possible using mainstream physics) would be to send an FTL ship very far away that has a ginormous (gi! nor! mous!) telescope. They could then watch the photons that Alexander sent into space the day he blew out those candles.
Then we'd know!
And, that's similar to the questions about the dimensionality of the universe. There are some theories now that seem plausible (though unlikely) that eventually would allow the collection of sufficient data to answer the question.
