Light Pollution and the End of the Construction of Imagination – Part 2 5855
Well, as I said in the previous article, I grew up and became a scientist. Not an astronomer, but a biologist. A biologist passionate about the stars. And many may ask: why didn’t you study astronomy? There are three reasons for that. The first is that I love biology. The second is that I was never good at mathematics. And the third is that I discovered that astronomers nowadays barely look at the sky. Telescopes work automatically, providing data to be analyzed later. That romantic astronomy of the past no longer exists. It was almost poetic, because imagination was the fuel for those scientists. Therefore, in cases like mine, it is much better to remain an amateur.
This reminds me of a curious anecdote in which the writer Isaac Asimov is said to have refused an invitation to visit a factory where robots performed tasks on assembly lines, because he did not want to compromise his imagination.
Returning to my story, when I was 21 years old, my father surprised me by taking me to a well-known store and buying a telescope. It was a relatively simple instrument, with a 60 mm aperture, but it allowed me to see the surface of the Moon perfectly, as well as Jupiter’s four largest moons and even Saturn’s rings. I don’t even need to say how I felt, do I? I became a child again! And that telescope is still here with me today, 30 years later.
But here comes the bad part, which gives these two articles their title… Light pollution has reached extremely high levels, to the point that in large cities, when you look at the sky, you see very few stars, only the brightest ones. City lights have erased the night sky. What child today will look up at the sky and be enchanted by all that immensity? Who will feel themselves on the shores of the cosmic ocean, as Carl Sagan said in the first episode of the classic series Cosmos? How will imagination be built?
In the same way, the inspiration of many poets and artists will be compromised. A child today, upon hearing stories of a time when the sky was filled with shining stars, might think that either the batteries ran out and no one replaced them, or that the bulbs burned out and no one changed them. It is still a child using their imagination, but without having experienced one of the most beautiful spectacles of creation.
That spectacle is still there, happening, and it will continue to happen for a very, very long time. Or rather, as long as time exists, it will continue, but with a curtain separating the stage from the audience. Today there are movements and campaigns aimed at solving this issue, but I believe it is a great challenge to overcome. Until then, one alternative is to leave large urban centers and seek regions far away, at least 50 km from these cities, where one can truly enjoy the magical view of a clear and genuinely dark sky.
I always wish clear skies to everyone, and ad astra!
