Let's Decode The Cosmos Together 💜

  Image 1: setup of vs code  When people post their Data Science journey online, they usually show beautiful graphs, machine learning models, and polished GitHub repositories. Very few people show the reality. The first week is mostly confusion. You don't struggle with Artificial Intelligence. You struggle with Git. You struggle with Python environments. You struggle with why a library refuses to install after following five different YouTube tutorials. This blog is my complete Week 1 documentation. Not only what I learned, but every command I used, every mistake I made, why those mistakes happened, and how I fixed them. If you're starting Data Science on Ubuntu, especially using VS Code, Jupyter Notebook, GitHub, and virtual environments, this article may save you several hours. My Goal I am documenting my entire journey publicly. Not because I already know Data Science. Because I don't. I want every future researcher or student to see what le...

If you're a physics student interested in cosmology or astrophysics, installing Python is only the beginning. A proper research environment should be clean, organized, and easy to maintain as your projects grow more advanced — and getting this right early will save you hours of frustration later. When I started preparing my Ubuntu laptop for scientific computing, I quickly realized that simply installing Python wasn't enough. I needed tools for numerical computation, symbolic mathematics, data analysis, visualization, and interactive notebooks — all while keeping project dependencies isolated. T his guide documents the exact setup I used to build my Python research environment for cosmology and astrophysics work. If you're just starting out, you can follow along step by step. Why Ubuntu for Scientific Computing? Ubuntu is one of the most widely used operating systems in research and scientific computing. It offers a stable environment, powerful terminal tools, e...

  When the Ground Gave Way: My Mental Health Crisis in Class 12 and the Long Road to Diagnosis A note before you read: this post talks openly about panic attacks, hospitalization, psychiatric misdiagnosis, and medication. If this is a hard topic for you right now, please feel free to skip this one, or come back to it when you're ready. Disclaimer: This article is a personal account of my experiences. It is not medical advice. Every mental health condition is different, and treatment decisions—including medication—should always be made in consultation with a qualified mental health professional. In my last post, I told you about the momentum I'd finally built in early Class 12 — coaching that was working, grades that were climbing, a plan that finally made sense after a year of teaching myself from scratch. I said the next chapter would be harder. This is that chapter. The Ground Shifting Again Partway through Class 12, my school reversed its earlier promise to support competit...

The Catalyst at 14 : The 8th-Grade Moment That Sparked My Journey to Cosmology How a rural classroom, a science teacher, and a five-minute video of the International Space Station set an aspiring cosmologist on her path. Some nights, I still stand outside and look straight up, asking the same question that has followed me for almost a decade: how did this universe begin, and how will it end? It's a strange question for a teenager to carry. It's an even stranger one to carry growing up in a small rural school, where "space" mostly existed in textbook diagrams — not in real conversation. But before I knew a single equation, before I understood what "research" even meant, before I had ever even heard the word cosmology — someone handed me a telescope I didn't know I needed. Not a real one. Just a phone screen, a science teacher, and one ordinary class in 8th grade. This is the story of how my journey toward cosmology actually began — and the first ...

The Big Bang: Understanding the Birth of Our Universe From the stars shining in the night sky to the atoms that form our own bodies, everything in the universe has a shared origin. One of the greatest questions humanity has ever asked is: How did all of this begin? Scientists have spent decades searching for an answer, and the most accepted explanation today is known as the Big Bang theory. Let’s explore this idea in a simple and meaningful way. What Is the Big Bang? The Big Bang was not an explosion in space like a bomb . It was an expansion of space itself. If we imagine playing the universe’s history backward, we would see galaxies moving closer and closer together. Go far enough back in time, and all matter and energy come together in a tiny, extremely hot and dense state. This moment marks the beginning of the universe, around 13.8 billion years ago. At that instant, space and time as we know them began to exist. The universe then started expanding and cooling. As it cooled, tiny...

Designed by Muskan jain through canva.com Quasars  Explained: The Brightest Beasts of the Universe Imagine looking up at the night sky and seeing what looks like an ordinary star—but it's not. It's something far, far away, much brighter, and more powerful than any star we've ever seen. These mysterious, ultra-bright objects are called quasars. Though they appear tiny, quasars outshine entire galaxies. But what are they, really? Are they stars? Are they black holes? Are they dangerous? Let’s dive deep into the world of quasars—some of the most powerful and puzzling objects in the cosmos. 🔭 What Are Quasars? The term quasar known for "quasi-stellar radio source." When astronomers first discovered them in the 1950s, they thought they were stars but they was strong even they couldn't Imagine what they found in this huge cosmos . Initially they thought about this brightess object as star because they are point-like matter looked in telescopes. But their light tol...
