On what basis do you claim the perspective of the spaceman or physicist is superior to the worm?
I see the 'human superiority' stance as the greatest conceit, and trace it back to Genesis. Science has only recently (2014, I believe) officially declared that mammals, pets, have feelings and actually 'think'. Of course, that's had to admit, when we use them for experiments to benefit the 'human race', and torture of livestock is the norm.
"What if" questions are those of the true scientist - forever challenging the status quo. Anyone can be a technician - but to dream .... string theory! Look up the tale of a dreamer, who was recognized posthumously. : )
