Formation of the Solar System (सौर मंडल का निर्माण)

Formation of the Solar System (English) The formation of our solar system began about 4.6 billion years ago from a giant molecular cloud composed primarily of hydrogen and helium. This cloud also contained traces of heavier elements. Over time, a nearby supernova or some other disturbance likely triggered parts of the cloud to collapse under their own gravity, forming a dense, rotating region known as the solar nebula. As the nebula rotated, it flattened into a disk, with the majority of the mass concentrating at the center to form the protosun, or the early Sun. Gravitational forces caused the center of this disk to heat up, initiating nuclear fusion in the protosun and eventually igniting it as the Sun. The remaining material in the disk began to clump together through a process called accretion. Tiny dust particles collided and stuck together, gradually forming larger and larger bodies. Closer to the Sun, where temperatures were higher, rocky and metallic materials condensed to form...

Big Bang theory (बिग बैंग थ्योरी (हिन्दी)

Big Bang Theory (English) 👋👼👋👋 The Big Bang Theory is the most widely accepted explanation for the origin and evolution of the universe. It states that the universe began as a single, incredibly hot and dense point about 13.8 billion years ago. This point, often referred to as a "singularity," began expanding rapidly in a massive explosion, which we call the "Big Bang." Key Concepts: 1. **Singularity**: The universe started as an extremely small, dense, and hot point. 2. **Expansion**: From the singularity, the universe began expanding. This expansion continues even today. 3. **Cosmic Background Radiation**: After the explosion, light from the initial burst of energy remains throughout the universe as cosmic microwave background radiation. 4. **Formation of Galaxies and Stars**: As the universe expanded, matter began to clump together to form stars, galaxies, and eventually solar systems. 5. **Continued Expansion**: Observations show that galaxies are moving awa...
