One of the things I do know is we know very little about our universe. Even though we think we know a lot, and we do know a lot more than we used to, we have a lot to learn about our universe.

I have a vast curiosity about our universe, our origins, and its probable future.

Time is change; we measure its passing by how much things alter.

There comes a point in your life when you realize how quickly time goes by, and how quickly it has gone. Then it really speeds up exponentially. With that, I think you start to put a lot of things into context; you start to see how huge the world is, and really, the universe.

In the future, maybe quantum mechanics will teach us something equally chilling about exactly how we exist from moment to moment of what we like to think of as time.

Human self-understanding changes with time, and so also human consciousness deepens.

I'm more aware of time. The element of time.

I'm fascinated by the fact that we can't grasp anything about time.

We all know we have a prescribed amount of time on Earth. We just don't know how much.

Time changes everything except something within us which is always surprised by change.
