What is a time loop? It is a plot device in which periods of time are repeated and re-experienced by the characters, and there is often some hope of breaking out of the cycle of repetition.
The time loop is the center of the loop quantum gravity, or loop theory as commonly known. The theory of quantum gravity, merging quantum mechanics and general relativity, suggests that space and time are quantized, analogously to the way quantities like energy and momentum are quantized in quantum mechanics.
The theory can be applied to many simple things in life. Or you can use it to answer some more philosophical questions. Before we were smart enough to write, we pondered about the stars and the heavenly bodies. We tried to understand the meaning of life and death.
The loop theory can be used to answer questions like is there a creator. What is the meaning of life, and so much more. This documentary shows how the physics theory can be applied to life’s questions.
