This is what causes things in the universe to break down and change. It's the reason why nothing in the universe ever seems to be eternal. To figure out a way to beat the law of entropy would be to conquer death itself.
Understanding what is inside a quantum singularity or (black hole) would likely lead to a unified theory of physics. In other worlds, humans would have full understanding of how all the forces universe work together to create what we experience as reality.
This question is actually a subquestion of "can we beat the law of entropy?". Because the breakdown of the human body and mind can be viewed as change in entropy.
Eradicating these diseases will likely take technology and coordination that doesn't exist today but if we succeeded it would greatly improve the human condition.
