After all, we're talking about type III technology here. If they can build these quasi-stellar ships, perhaps they can have whole fleets of them, and they are constantly flitting about the galaxy. Here's a calculation to perform: Take the energy output of a quasar, and convert that into energy momentum for all the spectra they emit. Work out how much momentum is being thrown away from the quasar, and assuming it is all going one way, see how much would be imparted to a ship the other way. From that work out what kind of delta-v we could be getting for ships of various masses. ----------------------------------------------------------------- gopher://quux.org/ conversion by John Goerzen of http://communication.ucsd.edu/A-News/ This Usenet Oldnews Archive article may be copied and distributed freely, provided: 1.
