Stars running out of hydrogen fuel, which lead to nuclear fusion
Giant Stars collapsing, lead to a supernovae with necessary conditions to forge most of the elements on the periodic table. The result of all of these perfect conditions and ingredients was the birth of something we know today as chemistry. 92 new elements each different that interact with each others in complex ways.
These are some of the new elements that were created in this process
These new elements throughout history have been proven to be extremely useful. One element that has been seen constantly throughout history is iron, or a stronger version called steel. We use steel almost everything. Roads, railways, skyscrapers, and airports all require the assistance of steel, in some way. Steel was also used heavily in a period of time we call the industrial revolution.
