  • Forget everything you've learned about the flux capacitor, gigawatts, superheroes flying backwards around the Earth, or the TARDIS, because today we're going to answer the age-old question, is time travel even possible?
  • Let's find out on today's episode of...
  • Let's start with what you can't do.
  • There's a really good chance that we can't travel back to, say, the invention of the wheel, not just because it's mean to steal a caveman's invention, but because experts believe that it's actually not physically possible to go backwards in time.
  • In very basic terms, this is because we'd need a bridge between the past and the present in order to travel back in time, like a wormhole.
  • A wormhole is a concept that Albert Einstein came up with back in the 1930s.
  • They act like shortcuts that connect two distant spots in space.
  • Scientists in the 1980s added to this theory by suggesting that wormholes might be able to be used like a time machine, even if that were true.
  • There are some pretty big problems with traveling back in time that way.
  • The main problem is that we don't know how to make wormholes yet, and even if we did, you'd only be able to travel back in time to the moment the wormhole was created.
  • And since cavemen probably spent more time hunting saber-toothed tigers than they did creating wormholes, we probably won't be traveling back there anytime soon because there's just no way to get there.
  • Traveling into the future, on the other hand, is a much more likely possibility.
  • This is thanks to one of Einstein's theories called time dilation.
  • The physics of space and time can get pretty confusing, but the basic idea is that time passes more slowly for a moving clock than it does for one that's staying still.
  • Pretty cool, but what does that mean for traveling into the future?
  • Well, imagine you got into a spaceship and flew super, super fast through the galaxy.
  • Since time moves more slowly as you fly at warp speed, time would pass faster for people on Earth than it would for you.
  • So, by the time you returned back to Earth, you would be in the future.
  • And they say science isn't cool.
  • And now you know that time travel is possible, just not in the way we picture it in the movies.
  • Comment below if you have a burning question you'd like to know the answer to.
