What we talk about when we talk about time travel: going back to kill
Hitler, Back To The Future, treading on butterflies causing irreparable
damage to history, Doctor Who, whether or not it’s ethical to use it to
cheat on the lottery or sports gambling or whatever, Bill & Ted’s
Excellent Adventure. What we don’t talk about when we talk about time
travel: whether it actually exists. Or will exist. Or has existed. We
don’t know, this wibbly wobbly, timey wimey stuff kinda messes with our
tenses a little. The idea of being able to travel backwards or forwards
through history has appeared in countless forms through pop culture,
conversation and daydreams for ages, but how come we don’t discuss
whether it’ll actually ever be real?
Does it just seem too beyond the pale? Is the the idea of time travel
so beyond the realms of possibility that we don’t even consider that it
could be real? Well, we’re here with good news! Not from the future,
sadly, just in the grimly predictable present. A grimly predictable
present that includes quantum physics, Higgs Bosons and other science-y
things we don’t quite understand but apparently have something to do
with a conceivable way for us to travel through time. No less a genius
than Stephen Hawking spent years looking for a reason that time travel
couldn’t exist, only to find the concept didn’t contravene any laws of
physics, eventually admitting “time travel may be possible, but it is
not practical”.
Plus there’s that history of time travel in our culture has
frequently strayed into the non-fiction – so long as you’re inclined to
believe the possible crackpots that are discussing it – all of which
adds up to some pretty compelling pieces of evidence that prove time
travel is real. Ten, in fact
