I’m a huge Science Fiction fan. But I don’t know who Charles Stross is. (I think I’ll have to find out though.)
In any case, Charles Stross has a blog, and on this blog he recently wrote an article about why he thinks that colonizing other planets is completely unfeasible.
Sad to say, he makes a very valid argument. But I’m still going to read Science Fiction about space colonization and I’m still going to enjoy it!
