The transporter: Star Trek’s most futuristic technology, allowing instantaneous travel between any two points, all with a swirly special effect.
Or is that a lie? Is the transporter actually, well, a suicide box?
You must admit, CGP Grey makes a convincing case, and it’s a funny watch even if you have heard the argument before. Yes, it’s our old friend the Teletransportation Paradox – essentially, are you still you when you step off the transporter pad, or does the machine actually kill you every time?
Grim news for the crew of the Enterprise, but then again, if you’re the Doctor, you’re laughing right now.
