Energy

E=MC²

We all know this equation, right? It's the most famous equation any scientist has ever written. We all know, it changed our life forever. 

It was the first ever attempt to measure the creation of energy. Before this, energy was practically never created by humans. It was the first of it's kind attempt to open the eyes of humanity to the possibility of creating an energy source.

So what the heck was happening before Einstein wrote this equation. Every other equation that involved calculation of energy, was actually calculating how much energy would get converted from one form to the other (or will be lost/wasted). We all read, "Energy cannot be created or destroyed, it can only be converted from one form to the other" Remember! But this view was challenged by Einstein's equation. It clearly said, You can create energy.....from mass.

Before this equation, the ultimate source for all energy around us was the Sun, which essentially worked on the same principle to create energy. It converted mass to energy. And here we were for the first time, trying to compete with nature, or the God, for now we were capable of creating energy.

I believe Prof. Einstein was the person closest to God. His work unveiled how the cosmos was at work and why.

The famous equation formed the basis of Nuclear fusion and fission reaction.

For any nuclear reaction to begin, and start generating energy, extremely high temperature is required. For man made nuclear fission reaction, humans could create such a condition, to kickstart the reaction. But how would such high temperature be attained at Sun, to begin with. Why would a Gas ball, suddenly get heated to extreme temperature so that fusion reaction could begin. If we answer this question, we will know why stars shine. Why every morning sunlight gives us life and how it all began.

When clouds of gases approach each other, they get attracted due to gravitation and start collapsing. More they collapse, heavier they become and attract more clouds of matter. This spirals an unending matter getting attracted to this lump of gas, which gets denser and denser and in the process gets heated up to extreme temperatures. At a right threshold temperature, nuclear fusion Kickstarts and life begins. The star becomes alive. The possibility of life in a nearby planet is now there.

Its "Gravity", thats the source of life, in the end.
