- jlgreco 13y agoBring back Project Orion and generation ships to alpha centauri become feasible, just hard: http://en.wikipedia.org/wiki/Project_Orion_(nuclear_propulsion)#Interstellar_missions http://en.wikipedia.org/wiki/Project_Orion_(nuclear_propulsi... I don't know of anyone that is seriously looking at Orion anymore though. I suspect that whatever will eventually take us there will be to Orion as the Flying Scotsman is to Hero's Engine.
- qxcv 13y agoA trip to Alpha Centauri would be decidedly intra-galactic; the distance from the Sun to the edge of our galaxy is on the order of 4300 times the distance from the Sun to Alpha Centauri.
- jlgreco 13y agoYes, calling it "cross" galactic would certainly be stretching the definition of "cross". Though I suppose a "cross country" race is across the "countryside" though not across the country. ;)
- yk 13y agoJudging from the last two space operas i have read, the fashion is sending transhumans on single generation ships ( and playing with internal clocks to manage the subjective boredom). And there are certainly a few people looking at interstellar travel. A great blog about this is http://www.centauri-dreams.org/ http://www.centauri-dreams.org/
- jlgreco 13y agoCharles Stross's (HN: cstross) Accelerando has a nice treatment of this. I think Orion ships are something that we could attempt to start building today though, no need to wait until the singularity.
