The Cosmic Perspective
The Cosmic Perspective
I must say I've always been one to want to discover my ancestry. Having grown outside my home country for my entire childhood and the better part of my teenage years, I had this need to connect to whatever it was that made me who I was - ancestry, lineage, bloodlines, that kind of thing. It filled me with pride that there was a miniscule chance that I had some true ancient Egyptian blood running in my veins, that I could even partially be affiliated with one of the most intriguing ancient civilizations of the world – one that shaped our current knowledge in many ways.
So, about a year or
so ago, I started harboring this real interest in astrophysics. I mean I always
loved the occasional space documentary, or sci-fi movie that had humans
befriending aliens or roaming the far ends of our galaxy in search of…you know,
important stuff. But my interest in the world of cosmology has since soared to
new heights; I want to be able to understand the underlying principles that
govern celestial phenomena. Like, why exactly are some planets rock-based while
others are almost entirely gaseous? Or, why would Mercury and Mars orbit the
sun rather more elliptically than the rest of the planets in our solar system? Or, how big could the universe
possibly be? Was there only one universe? Could there be a multi-verse now?
And, what even is “now” supposed to be? If spacetime
could warp, then could someday humans warp their time as well, so that we were
able to adjust this dimension as we adjust other tangible elements of our
reality? All these questions, together with a deep fascination for Einstein’s
theory of general relativity, prompted me to (finally) pursue some answers.
“Astrophysics for
People in a Hurry” is not just a very well-written and humorous explanation of
the basics of astrophysics. It’s also an eye-opener; a kind of wake-up call to
the average person. At the beginning of this book I was mesmerized by the
simplicity of Tyson’s portrayal of some pretty complex theories. And by
the end of it, two distinct conclusions were crushing me: that our world was
tiny in a stupendously huge universe, and that all our earthly squabbling is,
at best, petty. And then it hit me – albeit slowly – that it really shouldn’t
matter at all which part of this lonely planet I hail from. Why should these
political lines we draw on our maps be of so much consequence on our lives, and
on how we perceive our identities and relationships as humans? I don’t know if
we can afford that kind of divided thinking any more. Not with our planet
suffering from the strain of our political games, which deplete its stock of
natural resources more aggressively all the time.
I
think I’m choosing not to know my ancestry because it simply no longer matters
to me. It makes no sense, from a cosmic perspective, to think along those
racial lines. More importantly, it serves no purpose. After deeply considering
how small we are – and by extension how precious we are – in the ever-expanding
fabric of the universe, it is both liberating and empowering to be
able to say this very literally: I’m a citizen of Earth.
