Physics is the only science that explicitly studies time, but even physicists agree that time is one of the most difficult properties of our universe to understand. “We choose to examine a phenomenon which is impossible, absolutely impossible, to explain in any classical way, and which has in it the heart of quantum mechanics. In reality, it contains the only mystery.” : Richard Feynman Science Documentary The Science of Time Quantum Physics BBC Documentary BBC documentary 2021 Documentary BBC Documentary 2021
