For centuries, physicists and scientists have been consumed and obsessed with the idea of making a fully working perpetual motion machine. But, unfortunately, no one has succeeded yet, which begs the question: Are perpetual motion machines even possible?
So what is a perpetual motion machine? According to Wikipedia, "Perpetual motion is the motion of bodies that continue forever in an unperturbed system. A perpetual motion machine is a hypothetical machine that can do work infinitely without an external energy source".
However, each new perpetual motion "invention" would fail time and time again. This is because of one fundamental law in physics called the law of Conservation of Energy. It states that energy can't be created or destroyed, and theoretical perpetual motion machines seek to create energy without transfer or "creating free energy". This violates our understanding of science.
Perpetual motion machines would literally solve each and every global problem we are faced with, from electricity and transportation to water. Unfortunately, though, they seem physically impossible.
