Abstract

This paper examines the concept of the four fundamental interactions of nature: gravity, electromagnetism, strong and weak interactions. The main focus is on gravity as an exceptional force that does not have a confirmed quantum carrier of the interaction - the graviton. It describes how the Standard Model describes three of the four interactions through quantum field theories, while gravity is still based on Einstein's classical general theory of relativity. It explains why creating a quantum theory of gravity is a difficult task: standard methods, in particular renormalization, do not work for the gravitational field, which makes it impossible to combine general relativity with quantum mechanics.
