There is a need to understand quantum gravity in depth. 

Within the context of quantum mechanics and quantum field theory, three of the four basic forces of physics are explained. 

Gravity's fourth force It is based on Albert Einstein's theory of general relativity. This is referred to as quantum gravity. 

Quantum gravity is a branchof quantum physics that aims to describe gravity using  quantum mechanics concepts. 

However, there are several issues that have still to be resolved in order to truly understand quantum gravity. 

The area of quantum gravity is continually evolving, with theorists investigating alternative approaches to the problem. 

But I believe we need to reconsider our attitude to gravity. 

Understanding gravity as a force may also be the source of many issues. 

Gravity may be the source of many different forms of energy in the cosmos, as well as governing speed, time, and difference in many ways. 

In the next article, we'll look at several viewpoints on gravity.
