| Wormhole Transit (2002) | ||||
 | Done for the UK magazine Astronomy Now, this is a conceptual illustration of a wormhole. These are hypothetical tunnels through spacetime that permit you to travel from A to B faster than light would go if light took the long route. They might also be used for time travel. If they actually exist — and it's a big "if". See also Bubble Universes. |
