Fortunately for Daryl, Major Kaidan Alenko, second human Spectre and certified (if quiet) badass is also a giant nerd who's consumed more science fiction than he's likely to admit to. Absorbing some layman's definitions are part of the package. Bracing his back against the tree, he frees his hands to gesture as he talks.
"OK, so say you've got a road map. That's two dimensions, flat on a page," he says, hands miming leaves of paper. "If you fold that page in half, stick a pin through the map and then unfold it, you've got an entry hole and an exit hole, at different points on the map. Now we've got the world we live in, that's three dimensions, four if you count time. The theory of wormholes says that a wormhole's a connection between two different, distant points, like the pinholes in the map."
