Wormhole
A shortcut through spacetime — that the universe almost certainly won't let you use.
§ A first look
§ Depths
Six ways into the same idea — from bedtime story to chalkboard. No order required.

Told like a bedtime story.
For a curious 10-year-old. No jargon. Just a picture in your head.
Take a flat sheet of paper and put two dots on opposite corners. The shortest distance between them is a straight line across the paper. Boring. But if you fold the paper so the two dots touch, you can poke a pencil through both at once. A wormhole would be exactly that fold — a shortcut through space itself. Einstein's equations allow it on paper. Physics, in practice, looks at this idea, narrows its eyes, and asks several pointed questions about exotic matter you don't have. So: no, you can't book one. Yet.
§ Strange but true
- 01The universe is stranger than your intuition. This is a rule, not an exception.
- 02Every fact in physics was once an outrageous guess. Most still feel like one.
- 03If it doesn't bend your brain a little, you haven't read it carefully enough.
