We are not only observers. We are participators. In some strange sense this is aparticipatory universe.

Time is what prevents everything from happening at once.

We will first understand how simple the universe is when we recognize how strange it is.

No space, no time, no gravity, no electromagnetism, no particles. Nothing. We are back where Plato, Aristotle and Parmenides struggled with the great questions: How Come the Universe, How Come Us, How Come Anything? But happily also we have around the answer to these questions. That's us.

Spacetime tells matter how to move; matter tells spacetime how to curve.

We all know that the real reason universities have students is in order to educate the professors.

In any field, find the strangest thing and then explore it.
