The genesis of the first molecules part 2 !!

To answer the previous question about how molecules heavier than iron are created let's look at the problematic from a physical perspective and analyse the limitations of the former procedure.

Heavier molecules require an incredibly powerful energy to be synthesised that not even a star, during its lifetime, can produce so how can we gain such an immense energy?!

The answer is so simple, the destruction of the star generates greater energy than the creation itself, the phenomenon is called a supernova and it's characterised by the projection of the stored material accompanied with an unbelievably blinding beam of light, this event is so energetic that the fusion reactions goes wild forming elements heavier than iron like gold, platinum, uranium ...

And that's not it, the newly produced elements are then projected into the cosmos and mix with the gas that is still there from the cosmic inflation. 

The history then repeat itself, gas clouds now containing many elements we mentioned before besides the original atoms of hydrogen and helium form new stars by attracting matter and so on every cycle of newborn stars relies on the previously formed molecules to generate new ones and this how all the 118 elements discovered until now are produced and possibly in another star cycle where the nuclear fusion uses the heaviest elements like Tennessean and Oganesson that have the highest mass amongst the other elements will generate new breed of atoms with greater molecular weights, maybe they already exist in other galaxies bigger than ours or better say older than the milky way, the reason is, they have possibly experienced a lot more star cycles and heavier element's fusion maybe if there are other life-forms in the universe some  might already have a periodic table of 300 or 500 elements and maybe a lot more.
