Sitara Tales
Sitara ~ Sanskrit for star 
 

Grasping the ultimate purpose/reason for being of the Universe is knowledge beyond our reaches. Science, analysis and collaboration in today's global world is by far our  most compelling tool. With these, we have gone beyond the outer edges of the Solar System, delved into the Cosmic Microwave Background in an attempt to comprehend the past, and have peeked into the quantum workings of the universe simultaneously. 

Sitara Tales is a collection of pieces that present some chosen phenomena of our universe, and my mind, written over the past decade as I  took a step to quench my thirst in understanding the mechanisms of our Universe.

Photograph of the Month

July 2024: Celestial Seas

Lately, I've found myself entranced more than usual, by my admiration for the seas. While reducing radio astronomy data and sifting through catalogs of cataclysmic variable stars, I play deep sea films in the background in an attempt to blend my two loves - the seas and the skies. So, it is only appropriate that this month's photograph reflects this. This image of the Caribbean Sea was taken from the International Space Station. The deeper blues mark deeper depths while turquoise shades dominate shallower waters. 

Earthly waters are thought to have celestial origins, with a popular theory postulating collisions of comets and asteroids with prehistoric Earth setting the first seeds of water, and hence life. Studies show that the make-up of asteroids match closely with the chemical signatures of the oceans. This further cements the need for further sampling of asteroids and comets with missions such as the Rosetta Probe and OSIRIS-REx.

Unpredictable, Shy and Mysterious Stars

Do we live in a simulation?

Excellent question. I wish I had a definite answer. Short answer: there is no way we can verify this as of now. Long answer: read on! I spoke to two of my professors, both theoretical physicists (shout-out to Prof. Mike Gunn and Prof. Martin Long) about an answer to this question over the last few months and in a nutshell, they both had the same thing to say - we might very well be living in a simulation but we cannot know this for a fact because the process of knowing this would imply breaking the simulation and stepping out of it.

Browse through my virtual bookshelf and read some reviews on the several books I'verecently read. If you give them a read, let me know what you think! I'd love to start a conversation.

Peter Scott-Morgan
This is my favourite book of all time. Few books have the charm of bringing tears to your eyes, make your heart full with the tales of love they paint, and challenge your mind to think outside the box with science and technology - robotics and AI in particular - all within 300 pages. In 2017, Peter found himself struggling to shake water off his leg, by the sea. What seemed like a one-off incident set him down a path of a year of diagnostics while he gradually inched closer to being severely disabled. Peter was diagnosed with motor neuron disease. Continue

This tale begins at the tender age of five. We finish the plate of rotis and most likely our routine dinner time special of cabbage sabzi (bandha gobi tarkari in Odia) in our three bedroom apartment above Papa's office room in the heart of Dar es Salaam's industrial area, Kurasini. As Mama begins clearing the table, I am already strapping on my sandals and Papa is getting up to wash his hands. Shortly after, Mama is at the door with us and we are walking down a corridor towards a mesh gate on the first floor of the building. Upon stepping out, we arrive at a balcony. My tiny legs barely let me see what lies above the concrete barrier and Papa gently scoops me in his arms. In the distance, I see some distinct buildings in the 2006 skyline of Dar. I can see the Twin Towers, and the PPF Tower. I see the national port's cranes just barely grazing my view at the edge of the highway. I hear some lone cars drive by and see a couple of askaris, security guards, walking throughout the empty yard  directly infront of us. I probably see two trucks parked, with a couple of containers in the workshop bays. Despite this, the parking yard is still fairly empty and to me, it is my paradise. What can be more exciting than watching trucks with cars on two levels, walking joyfully with Mama Papa after dinner, and watching the stars above my head? Continue
