Why can’t you turn back the time?

"Time waits for no one, so why should I?"

It is impossible to turn back time because of the fundamental laws of physics. According to the laws of thermodynamics, energy can be neither created nor destroyed, and the total amount of energy in the universe is constant. This means that the energy that was used to move forward in time can never be reversed. Additionally, the theory of relativity states that time is relative and that the flow of time can be affected by gravity, speed, and acceleration. This means that the time that has passed cannot be reversed. Finally, quantum mechanics states that the past cannot be changed because of the uncertainty principle, which states that the exact position and momentum of a particle cannot be known simultaneously. Therefore, it is impossible to turn back time.
