My fascination with space technology and space exploration skyrocketed with the exhilarating news of India's Chandrayaan-2 mission, which dominated headlines in July 2019. The Indian Space Research Organization (ISRO) launched Chandrayaan-2 on July 22, 2019, with ambitious goals to explore the Moon's surface and enhance our understanding of lunar geology. Since childhood, the twinkling stars and the alluring presence of the Moon ("Chanda-mama") in the night sky had always piqued my curiosity. However, it was the live coverage of Chandrayaan-2's journey, despite its unfortunate crash landing, that truly ignited my passion for space research. As I delved deeper into the subject, questions flooded my mind: How far are these stars and planets? Why do we launch satellites into space? What exactly are satellites, and how do they benefit us? My exploration led me to uncover a wealth of knowledge about humanity's endeavors in space exploration. Space exploration began...

Imagine a passage through space and time—a shortcut connecting distant corners of the cosmos. In both science and fiction, these phenomena are known as wormholes. They defy conventional notions of space travel, offering a potential route to traverse immense distances in an instant. Literary Roots and Scientific Conceptualization The concept of wormholes first captured imaginations in literature, notably through Charles Dodgson's (Lewis Carroll's) "Through the Looking-Glass." Here, Alice ventures into Wonderland via a fantastical mirror—a metaphor for traversing universes effortlessly. Mathematicians refer to such phenomena as "multiply connected spaces," where disparate realms intertwine. From Theory to Physics: Schwarzschild and the Birth of Black Holes In the annals of physics, the genesis of wormholes dates back to Karl Schwarzschild's solution to Einstein's equations in 1916, shortly after the advent of the general theory of relativity. Schwarzsc...

Introduction: The Dawn of Destruction Can you imagine the world-changing in an instant? On August 6, 1945, an American B-29 bomber, Enola Gay, soared over Hiroshima and unleashed the unimaginable—a blinding flash followed by a mushroom cloud that forever altered human history. The atomic bomb, Little Boy, claimed 80,000 lives instantly. Three days later, Nagasaki suffered a similar fate with Fat Man, leaving behind a trail of devastation and sparking the nuclear age. But how does this fearsome weapon actually work? Decoding Atoms and Radioactivity Imagine peering into the heart of an atom—a tiny universe with a nucleus of protons and neutrons orbited by electrons. What if altering this nucleus could create a cataclysmic chain reaction? This is the essence of nuclear fission—the splitting of atomic nuclei—triggered by bombarding them with neutrons. The resulting energy release, coupled with gamma rays, forms the core of atomic bomb technology. The Manhattan Project: Science Meets Urgenc...

   “The future belongs to those who believe in the beauty of their dreams.”   ―  Eleanor Roosevelt     Today while  writing  this, I thought for the first time what I will be doing in the next five years of my life.  I believe that these will be some of the most important years of my life. In these years, I will be working toward becoming a space researcher with the Indian Space Research Organisation (ISRO). I have had an interest in astronomy since my childhood. It is very fascinating to know about something that is far beyond our sight. While learning about the solar system in school I got interested in finding out more about space.       I always had a curiosity for the twinkling stars and the attractive moon in the night sky. I used to ask myself “How far are these stars and planets? Why do we send satellites to these planets? Is time travel possible?” The Launch of Chandrayan 2 flooded the news and social media in ear...

I was wondering what Dark Science is? And started reading about it. In this article, I am trying to compile some research from various sources about this topic. This should help one understand the basics of Dark Matter. History of the Dark The Ancient Greeks were very smart and had made the universe simple; according to the Greek scientists, all our universe comprising are four elements, namely: earth, fire, water and air.  Their theories are simple and elegant, which states that by combining all four unique elements in special ways, one could produce all the diversity of nature from what we find around us. For example, earth and fire produce anything dry, air and water produce anything wet. Fun Facts - 1: Aristotle also suggested that there was a fifth element aether because it seemed strange that would make the stars of earthly elements. It would surprise him to learn that they comprised of  many elements found on earth and are so hot they could be said to be...
