Nice find Yodaman! This looks hopeful - albeit it much less so pragmatically than theoretically. Still, if I could visit another world in my lifetime, I think I would die a happy man
I know this is a little off-topic, but I must just point something out here - purely for fun. I'm no expert on this so I don proclaim to have my facts 100%, but radio waves move at the speed of light in a vacuum, afaik. So then
how would the ship communicate with Houston from Alpha Centauri? Just food for thought since I've seen radio-wave communication used over long distance in a number of sci-fi shows and always thought "how?". Somewhat of a fun afterthought for all this. I'd be curious to hear some theories on that.
@greenlig: You have an extremely valid point. To answer your question regarding the ocean as best I can, the reason humans want to go up and not down is basic human psychology. Human beings created most of their culture and religion based on "up". We placed Gods on top of high mountains, in the sky and, more recently, on other planets in space. I hypothesize that the reasons for this are likely:
Our association of flight with freedom (lots of obsession with flying in older mythology)
Our association of higher places with safety (ie safety from most predators could be found in trees - to go really far back)
Our association of the sky with life (The rain brought precious water to us, the sun brought safety from the dark and symbolised life).
From there, I believe it simply grew stronger as our ability to POKE the heavens evolved technologically. Eventually, "up" gained practical application in day-to-day life with air-travel, satellites, radio towers and possibly one day advertising on the moon (Coka-Cola logo fits *shudder*).
I think what happened from an imaginative standpoint is we discovered that the ocean had a limit - its bed - and we've more or less mapped it using sound waves (I think it was sound waves?) so although we can't see anything other than the general shape of the bottom of the ocean, it's been "demystified" in a sense. Space, on the other hand, seems bigger and that vastness appeals to us, especially our imaginations.
This may all seem very silly but we are a silly species and I will freely admit that I'm as big a sucker for space as the next guy
