Stephen Hawking: Time Travel?

Get the backstory at Letters of Note. Stephen Hawking isn't just smart, he's funny too! I'm actually working on a chart about time travel right now. Should be done in two weeks, or sooner if I fix my time machine.

Regarding time travel, Hawking has famously said, "If time travel is possible, then why don't we see any time tourists from the future?" Which seems like a really clever thing to say, but is actually really stupid. Carl Sagan called him on it by pointing out the obvious which is that time tourists wouldn't announce their presence, and could easily blend in assuming all they had to change is their clothes.

  1. Steve Jobs was a time tourist whose time machine was destroyed. he spent his whole life trying to rebuild it but died of time poisoning before he could do it.
