The bigbang starting

 The Big Bang theory proposes that the universe began as an extremely hot and dense point roughly 13.8 billion years ago. It rapidly expanded, cooling down and forming particles such as protons and neutrons within microseconds.

As the universe continued to expand and cool, it entered a phase known as the quark-gluon plasma era, roughly a few microseconds after the Big Bang. During this time, the universe was so hot and energetic that individual protons and neutrons could not form, and quarks and gluons, which are the fundamental building blocks of protons and neutrons, roamed freely.



Gluons are the carriers of the strong nuclear force, which is one of the four fundamental forces in the universe. They mediate interactions between quarks, which are the building blocks of protons, neutrons, and other hadrons. Quarks are elementary particles that combine to form protons and neutrons. They come in different "flavors" (up, down, strange, charm, top, and bottom) and carry fractional electric charges.


Over the next fraction of a second, the universe continued to cool and expand, allowing quarks to combine and form protons and neutrons. These protons and neutrons then came together through gravitational attraction to form simple atomic nuclei like hydrogen and helium. These nuclei were the building blocks for the first atoms.


The emergence of gluons and quarks was a crucial step in the early universe's evolution, eventually leading to the formation of matter as we know it today. This process set the stage for the formation of stars, galaxies, and the complex structures that make up our universe.

The bigbang (emerging of first atom)

 The emergence of the first atom in the universe marks a pivotal moment in cosmology, providing insights into the origins and evolution of our cosmos. This event is closely linked to the Big Bang theory, which postulates that the universe began as an infinitely hot and dense singularity around 13.8 billion years ago. In the first moments after the Big Bang, the universe underwent a rapid expansion known as cosmic inflation. As the universe cooled down, elementary particles began to form, eventually leading to the creation of the first atoms.  The first atom to emerge in the universe was hydrogen - the simplest and most abundant element. Hydrogen atoms consist of a single proton in the nucleus, orbited by a single electron. The process of hydrogen atom formation, known as recombination, occurred roughly 380,000 years after the Big Bang. Prior to recombination, the universe was so hot and dense that free electrons and protons couldn't combine to form stable atoms. Instead, the c...

India's pride -TheChandrayaan 3 -----reaches its final stage

Image
        India's ambitious third Moon mission, Chandrayaan-3, marked a significant milestone as it successfully completed its fifth and final lunar-bound maneuver on Wednesday. Over the course of three weeks since its launch on July 14, ISRO executed a series of maneuvers, progressively extending Chandrayaan-3's orbits away from Earth. With the recent maneuver, Chandrayaan-3 has completed its lunar-bound maneuvers and is now preparing for the detachment of its propulsion module and lander module. The precise firing conducted for a brief duration has positioned Chandrayaan-3 into a targeted orbit of 153 km x 163 km, marking the successful completion of lunar-bound maneuvers. ISRO tweeted that it's now time for preparations as the Impetus Module and Lander Module gear up for their respective journeys. The separation of the lander module from the propulsion module is scheduled for August 17, according to ISRO. Following its launch on July 14, Chandrayaan-3 entered lunar ...
