In my previous article “How it all started…”, I expressed on how a star fuse elements of our periodic table in its core.
Also, how star cannot fuse iron and it leads to a big supernova explosion.
The question arises, If this is true how do we find elements in periodic table which are higher then Iron are produced? For e.g. Gold, Lead, Plutonium, etc.
Our planet earth has about 510.1 million square kilometres in surface area. We are part of the solar system with sun in the centre. Our sun is whopping 109 times diameter then the earth.
Our solar system is roughly 122 AU in diameter where each AU (Astronomical Unit) correspond to 150 million kilometres!
Today with help of cosmic background radiation and other methods, we are able to trace back the sequence of events, which led to the creation of earth.
13.8 billion years ago, a catalytic event took place. We have named it “Big bang”. We are not certain what exactly caused this event. There are several theories but cannot be conclusively established.
