In this 4 part series, String Field Physicist Professor Michio Kaku will try and answer the question that many scientists, philosophers and free thinkers have asked and can never seem to answer: "What is time?" "Does time have substance?" "Does time ...have structure or dynamics" "Is time quantised?". Time is said to be the law which keeps all other forces in the universe from interacting all at once. However, at the core of physics forces push. They do not pull. So what is pushing time? The Big Bang? And if so, what pushed the force that caused the Big Bang? It is a conundrum.
Michio instead turns to the very fundamentals of what time is, what our sense of time is, what timing mechanisms exist in nature and how the universe operates, and how it needs to operate, in such a clockwork. (58:46)
