For context , the farthest known planetary body in the solar system is Pluto , which orbits approximately 39 AU from the Sun , and is also part of the Kuiper Belt , which scientists estimate extends as

Sutter Why Quantum Mechanics Defies Physics The full , weird story of the quantum world is much too large for a single article , but the period from 1905, when Einstein first published his solution to the photoelectric puzzle , to the 1960â s , when a complete , well-tested , rigorous , and insanely complicated quantum theory of the subatomic world finally emerged , is quite the . story This quantum theory would come to provide , in its own way , its own complete and total revision of our understanding of light . In the quantum picture of the subatomic world , what we call the
