Charlie Stross did, in my opinion, a better analysis ( https://www.antipope.org/charlie/blog-static/2007/06/the_hig... , discussed on HN at the time at https://news.ycombinator.com/item?id=2639456 ) where his math seems to show that even lossless matter to energy conversion with lossless[1] conversion of that energy to thrust wouldn't make interstellar travel feasible. [1] The word "lossless" alone ought to raise eyebrows since, as far as I understand it, FTL travel is far more plausible than circumventing the laws of thermodynamics. |

HN discussion of the article "The High Frontier, Redux" (the HN title was "Why we are unlikely ever to leave the solar system"):

The submitted article was very sound reasoning on why no one in humankind is ever going to make a trip to an extrasolar planet. The comments on the HN thread that disagreed with that conclusion showed appalling lack of consideration of physics or economics.
