Tom Everett: Elliot Langley

Quotes 

• Elliot Langley : The rules haven't changed much since Einstein. Ultimately Whether it's wormholes or warp drives, time travel requires you to go 186,000 miles per second.

  Dan Vasser : The speed of light.

  Elliot Langley : That's the rub because, so far, nothing has demonstrated an ability to do that.

  Dan Vasser : What about tachyons?

  Elliot Langley : Theoretical particles never proven to exist.

  Dan Vasser : So, time travel's impossible.

  Elliot Langley : No, just not proven. Five hundred years ago, we knew Pluto didn't exist. Five years ago, we knew it was a planet. Now, we know it's not. Did Pluto change? No. Did our understanding of Pluto? Yes.
