In this project we discuss possible ways to experimentally study quantum gravity. Quantum Gravity operates at the Planck scale so it is hard to study. So tests has to be done indirectly if possible. There are multiple theories on quantum gravity which can be used to probe possible quantum gravity effects. In this project we discuss various possible quantum gravity effects and ways to study it.

Problem of time one of basic problems in quantum gravity. When combining quantum mechanics and general relativity using Dirac's principle of quantization, the time variable formally disappears, and Schrodinger's equation takes the form of pure constraint equation called the Hamiltonian constraint equation. The problem is time is to derive the time evaluation of the universe from this constraint equation.
