Many have been worried about light pollution that obscures the sky and some have gone as far as speculating that the inability of city folks to view the stars overhead is eating into the human psyche. Those who have burned the midnight oil in North America to view the total lunar eclipse recently may be comforted by the fact that there are three more to follow soon. The sky is indeed interesting, but there are more interesting ideas to think about. Watching the sky is not going to change anything – thinking about what could be out there, may.
Conventional education methods have stressed such mediocre attempts to understand science – a trip to the planetarium and a stroll down to the backyard pond – on the premise that seeing, touching and feeling stuff will enhance understanding. In a world of accelerating abstract knowledge, such practicality comes with a huge cost. Real astrophysicists do not “look up” and real biologists are not enamored by the Petri dish. Knowledge comes from imagination and not by verifiable experiments. Mechanics and experimentalism can only sustain the status-quo and not advance it.
So, next time somebody implores you “to look up” to the heavens to learn, think about how much more could be learned by just looking down.
