I have an idea for an experiment in space. I don't know where to post it, so why not here. (this experiment is completely theoretical and might not be followed though for a long time) We should send a kid that's just starting puberty into microgravity and see the effects of this era of growth on the human body in weightlessness. It could be considered a bit pointless as most astronauts on long space trips would be adults, but imagine sending kids to Mars with adults. It's just an idea and we should probably start on primates.
"Space is big. Really big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist, but that's just peanuts to space." - Douglas Adams
