Wasn't sure whether to put this here or in off-topic...
In all honesty, I didn't read the article, just the first few sentences. But it made me immediately think of phase lanes in Sins!
To save you a click: "Gravitational corridors could help spacecraft ply the solar system like ships borne on ocean currents, it has been disclosed by scientists investigating space travel"
I guess those phase lanes weren't just to control where you could fly =P
