As you all know,
everything comes to an end. Every living thing must die and every non living
thing does decay, so its right to day everything existing has a time frame. We
know the usual like you throw away an apple and after some time it'll decay to nothing, plastic is also naturally
degradable but under normal circumstances it'll take more than 1000yrs to
decompose a small amount . Even the stars, earth, our galaxy and even our
universe has a time frame. Science has discovered what happens these things at
the end of their time frame and it is beautiful !
In layman's language i hope to convey a message about the beginning of life
Most of you have heard about the famous " big band theory " , not the tv show, the theory which says that the everything in our universe, all planets, stars, nebulas, black holes, every single thing floating in the dark void above us was once ( 13.8 billion years ago ) packed tightly together in something which is much much smaller than a hydrogen atom ( 0.0000000000592 meters ). That singularity with our whole universe inside it then exploded and with that big bang, our universe came to being. Don’t imagine a huge explosion out of which the planets and stars came out wholly but imagine a normal bomb going off, spreading outwards with gasses in all 3 dimensions. The leftover of this unimaginable explosion was ginormous amounts of gas clouds ( these were composed of hydrogen and explaining why just hydrogen gas clouds would require a more scientific approach which you are surely not interested in ), which travelled at astounding speeds and finally settled a few 100,000yrs later. This realm is the baby universe, there are no stars no planets just huge gas clouds called nebulae.
Believe it or not these gas clouds are factories manufacturing stars through the forces of gravitation. In these huge clouds, lets say a lump of hydrogen atoms coalesce together due to their random motion. Now this lump has a higher gravitational pull than other atoms and hence pull them towards it. The end result is like a snowball rolling down a hill, the more weight it gets the more faster it rolls but in this case the more molecules it attracted the more stronger its gravity got and so it attracted even more atoms. This keeps on happening till a point is reached when so much amount of hydrogen stuck together by gravity reaches a temperature so high that nuclear fusion takes place. Just to be clear, fusion is when 2 hydrogen atoms combine together to give a product of a single helium atom along with enormous amount of energy. That released energy then goes on to help other hydrogen atoms to make more helium and more enormous amounts of energy. That my friends in simple terms is how all stars work, including our beloved sun.
