Entanglement can best be understood as this: When subatomic matter is in a process together, subsequently the subatomic particles go apart from each other and go across the universe. When they do this, they will remain entangled. That means if you do something to one, the other one responds immediately, instantaneously.

It's been written about as "the overview effect." All I can give you is my perspective, but most all of the people who have been in space start to see the world without boundaries. You start to think about how we can keep doing these things we're doing that are destructive of the environment and destructive of the planet. It causes you to start to think things in a quite different way than we had before.

Undoubtedly we will go on to Mars in due course, provided we don't blow ourselves up with our stupidities in the short run. That's a possibility, too.

We call our intuition our sixth sense, but in reality it would be called our first sense, because it's rooted in quantum nature of reality. It was around long before our solar system and our planetary system were even formulated or even organized. It is at the basis of how our normal sensing works. So instead of being our sixth sense or even â€" using the parapsychological term â€" "extrasensory perception," it's not. It's at the basis of our perception, and that's the quantum world.

You get out there in space and say to yourself: that's home. That's the only home we have, and the only one we're going to have for a long time

We're at a point in history were we have to become a part of the neighborhood of inhabited planets, like a neighborhood of a community, which we have not even acknowledged that that community exists up until this point.

When I went to the moon I was a pragmatic test pilot. But when I saw the planet Earth floating in the vastness of space the presence of divinity became almost palpable and I knew that life in the universe was not just an accident.
