Why does the Philosophers' Stone not exist?

The Philosophers' Stone was determined to be unable to exist due to our more modern understandings of atoms. The Philosophers' Stone was a substance reputed to be able to transform, or "transmute" common metals such as lead and iron in to noble metals, such as pure gold and silver. However, we now know that to change one element in to another requires a bombardment of radiation particles, or an atom fusing process known as nucleosynthesis. Because of the massive amount of energy required in this, the cost in creating gold far outweighs the monetary profit. And since it's not possible without this expenditure of energy, the Philosophers' Stone has been deemed a myth.
