I picked up the book Black Hole Blues by Janna Levin partly because I was intrigued by the poetic title, and partly because I like reading about our dear Cosmos, and its many mysteries. The skies have given me endless joy, peace and continue to do so, even though light pollution in our suburban areas mean that we cannot see the stars, planets and stars as clearly.
Excuse me for a while, while I meander to a black hole of my own for a moment: I was appalled to note that a Russian startup intends to sell advertisements that can only be visible in the night sky. Are our products so important that we have to dwarf the shows the Cosmos puts up every night to sell toothpaste and whatever gawd-awful thing we contrive in our numerous factories? (I have a post clamoring and rattling in the brain waiting to get out on the number of contraptions that folks felt I must have, or I myself felt I must have, and now occupy valuable shelf-space in the home somewhere.)
Climbing out of the black hole then, the cosmos has given me endless joy and I indulge in dipping into its mysteries every now and then. What surprised me about detecting gravitational waves is the immensity of human endeavors. Theorizing and coming up with the supporting Mathematics to validate the concept is in itself a phenomenal achievement, but conceptualizing an experiment of such magnitude as to detect a stirring as faint as gravitational waves emanating when two black holes collide millions of light years away is astonishing.
As Janna Levin says, it is a project to fulfill a fool’s ambition.
“An idea sparked in the 1960s, a thought experiment, an amusing haiku, is now a thing of metal and glass.”
― Janna Levin, Black Hole Blues and Other Songs from Outer Space
The LIGO (Laser Interferometer Gravitational-Wave Observatory ) is astronomical in scope and dimensions. Janna Levin’s book takes us into the human dramas and the corridors of Caltech and MIT where much of this played out. While I did feel the flow and structure of the book could have been more crisp, and less about the human politics that plague undertakings such as these, it was nevertheless interesting.
As I read, I was amused at how humans unfailingly bring drama into our existence. At the altar of Science, many have sacrificed their egos, had their egos bruised, and have propelled or obstructed the flow of Science, but like a river it flows on and hopefully propels our understanding forward, not always cognizant of the applications of Science (One of my favorite sayings of Ursula K Le Guin:
When you light a candle, you also cast a shadow).
After the monumental setbacks and roadblocks along the way, it is a satisfying end to the book that the experiment finally paid off. Twice, it detected Gravitational waves as they passed through the Earth from the collision of two massive black holes millions of light years away.
We do not yet know how this will change our understanding of the Universe, and its applications, but we can be rest assured that both are underway. We have come a long way from the Sun God riding the sky every morning on his chariot, though I am reading a fascinating book on this very myth at the moment.
Human-beings are philosophers and tinkerers at the very core, are we not?
