Overview

When examining things as we perceive them in everyday life, it is sufficient to rely on Newtonian mechanics. However, when dealing with things on a very small scale or when dealing with objects very fast or with very large mass, Newtonian mechanics breaks down. Theoretical calculations fail to predict experimental outcomes.

It is in these situations that we turn to quantum mechanics and general relativity. Scientists agree that these are the best theories out there for explaining and predicting the physics occurring on these scales. However, they are not perfect. These theories applied to what we view every day result in minimal, even negligible, changes to the equations from Newtonian mechanics, but relativistic mechanics will not work on a quantum level. Quantum mechanics are likewise incompatible on a relativistic scale.
