Have you ever wondered why objects fall to the ground? Or why planets stay in orbit around stars? These questions have intrigued scientists and thinkers for centuries, and the answer lies in one of the fundamental forces of nature: gravity. In this blog post, we will delve into the intriguing world of gravity, exploring its mysteries and shedding light on some lesser-known aspects of this force that governs our universe. Understanding Gravity 1. What is Gravity?    - Gravity is the force that attracts two objects with mass towards each other. It is what keeps us grounded on Earth and governs the motion of celestial bodies. 2. Newton's Law of Universal Gravitation    - Sir Isaac Newton formulated the law of universal gravitation, describing how every mass in the universe attracts every other mass. 3. Einstein's Theory of General Relativity    - Albert Einstein revolutionized our understanding of gravity with his theory of general relativity, which explains ...

Space, the final frontier, has always captivated humanity's imagination. From the moon landing to the discovery of distant exoplanets, our quest for understanding the cosmos continues to push the boundaries of scientific knowledge. One of the most enigmatic and pressing questions in space science revolves around dark matter, a mysterious substance that makes up a significant portion of the universe. In this blog post, we will embark on a journey to explore the intriguing world of dark matter, shedding light on what we know, what we don't, and the ongoing quest to unravel its secrets. The Cosmic Enigma: What is Dark Matter? Dark matter is a cosmic puzzle. It does not emit, absorb, or reflect light, making it invisible to traditional telescopes. Yet, its presence is inferred through its gravitational effects on visible matter and the large-scale structure of the universe. Scientists estimate that dark matter constitutes approximately 27% of the universe's total mass-energy co...
