Entropy is a theoretical property of thermodynamic systems. Entropy measures the degree of disorder in a system.
The laws of thermodynamics state that heat always move from hot to cold and never in reverse and this action is not reversible. If you have seen what happens to a bowl of water that is brought to a boil, you know, things get really disorderly within as heat increases. Therefore it implies that every system moves towards greater disorder, always! Also, that this is not reversible.
I was reading a book by Terry Virts, an astronaut, who made the convincing argument that there had to be a creator for the universe. The reason - Entropy. Almost nothing goes from a state of disorder to order and hence there had to be a creator for this order to even exist.
The problem is that through the Hubble telescope we have watched stars crash into one another and create new systems. New worlds and new planets.
If Big Bang is for real, Entropy would imply that the world should have never formed! How can an explosion result in order?
The only conclusion that one can arrive at, is that this theory is wrong! The world exists, we exist, evolution happened, that is proof that order can be created from disorder.
In a preprint posted online Thursday night, researchers at Google in collaboration with physicists at Stanford, Princeton and other universities say that they have used Google’s quantum computer to demonstrate a genuine “time crystal.” In addition, a separate research group claimed earlier this month to have created a time crystal in a diamond.
A novel phase of matter that physicists have strived to realize for many years, a time crystal is an object whose parts move in a regular, repeating cycle, sustaining this constant change without burning any energy.
“The consequence is amazing: You evade the second law of thermodynamics,” said Roderich Moessner, director of the Max Planck Institute for the Physics of Complex Systems in Dresden, Germany, and a co-author on the Google paper. That’s the law that says disorder always increases.

There was a time that everyone believed the world was flat and there was no way to disprove it. Then Copernicus and Galileo came along with the practical and not the theoretical. They ensured that all the physics textbooks in the world had to be re-written.
I think we are on the verge of some kind of discovery of that nature. Every physics textbook might have to be ripped up!
