Thanks to Curiosity Stream for supporting PBS Digital Studios. If you have perfect knowledge of every single particle in the universe, can you use the laws of physics to rewind all the way back to the Big Bang? Is the entire history of the universe perfectly knowable? Or has information somehow been lost along the way? [Intro Music] The laws of physics are equations of motion. They are mathematical rules that dictate how systems evolve in time. Newton's equations for classical mechanics, Maxwell's equations for electromagnetism. and the Schrödinger equation for quantum mechanics. These laws can be used to predict how the universe will evolve into the future. They are deterministic. Perfect knowledge of a system in the present perfectly predicts how the system will change ...
