Have you ever wondered why your coffee loses heat while sitting on your desk? How engines function? And how the Universe may end? There is one law that may provide answers to all these questions and it's the second law of thermodynamics.

There are three main components to this law. The first refers to the conservation of energy to heat and thermodynamic processes. The second law dictates that, in all energy exchanges, if no energy enters or leaves the system, the potential energy of the end state will always be less than that of the initial state.

This second law is particularly interesting as it can be used to predict how our Universe may end far far in the future. The theory goes like this: our Universe is constantly moving towards disorder. Eventually, all the energy in the Universe will be evenly spread out.

At this point, the Universe will become a dispersed soup of particles and radiation whose energy will be drained leaving everything just a fraction of a degree above absolute zero. The Universe will then be cold and empty.
