Traversable Wormholes and Time Travel | Feynman Lectures

Now, imagine you're an ant on a big rubber sheet. If you want to get to the other side, you've got to crawl across the whole thing, right? But if you're clever, you might fold that sheet so the two ends touch, poke a little hole through, and—snap!—you're there. That's a wormhole. It’s a shortcut through the very geometry of space that seems like it belongs in a cheap sci-fi magazine, but the math says the universe might just allow it. The problem is, gravity really wants to pinch that hole shut before you can even get your nose through, so you need to find a way to prop it open. To keep that door from slamming, you need something we call 'exotic matter.' It's stuff with negative energy density—which sounds completely nuts, like saying something weighs less than nothing. We actually see tiny bits of this in the lab with the Casimir effect, where empty space pushes things around because of quantum fluctuations. But to build a bridge big enough for a person, you’d need a lot of it, and we don't know if the laws of physics will let you pile it up like that. It’s like trying to build a house out of steam; it’s a beautiful idea, but getting it to stay still is the real trick. And here is the kicker: if you can actually make one of these traversable holes, you haven't just conquered space; you've conquered time. If you take one end of that wormhole, put it on a rocket, and zip it around at near the speed of light while the other end stays home, you’ve built a time machine. You step in on Tuesday and walk out last Friday. Now, the philosophers love to get a headache over whether you can go back and stop your parents from meeting, but as a physicist, I want to know if the universe has a 'chronology protection' system to keep things from getting that messy. Is the world truly that crazy, or are we missing a piece of the puzzle? 📚 Verified Sources & References Feynman, R. P. (1965). The Character of Physical Law. MIT Press. Morris, M. S., & Thorne, K. S.
