Begone you worshippers of Satan! Everyone knows that God created man in his image. Everything revolves around our planet, burn ye heathen speaking otherwise. Fall off the ends of the Earth! I always find it incredibly funny when people talk about things that are impossible. So let's take the thousands of years of human history and fast forward... I don't know... a few million years. Wonder if what we use to believe as fact changes at all? Nah, that's never happened before. Especially not in incredibly lesser amounts of time. Found it funny when someone asked what FTL was. I thought FTL was about time loops until a few posts in. Science Fiction does not need to be 100% scientifically accurate. You scientists and your constant disagreement, impossible to please all of you. Even if it was accurate at the time it could be disproved later. So... ya, I'll buy into a simply plausible explanation. Suspension of disbelief is pretty accurate, but hey... I would of believed in the possibility that the Earth was round. FTL was more popular with the whole space race back in the day. No interesting tidbits on space now-a-days. I do think there should be more books that contain planet/species building. Good use of the creative juices. Nanobots, A.I., and virtual immersion have gotten more popular lately.
