You will never find scientists leading armies into battle. You just won’t. Especially not astrophysicists -we see the biggest picture there is. We understand how small we are in the cosmos. We understand how fragile and temporary our existence is here on Earth. We understand there are bigger problems we need to solve as a species than what God you pray to.

We are all connected to each other biologically, to the earth chemically and to the rest of the universe atomically. That's kinda cool! That makes me smile and I actually feel quite large at the end of that. It's not that we are better than the universe, we are part of the universe. We are in the universe and the universe is in us.

The supermoon is a 16-inch pizza compared with a 15-inch pizza. It's a slightly bigger moon; I ain't using the adjective 'supermoon.'

What are we promoting in society? Well-behaved automatons that spew back what they learned in a book. That's not science. You can get a parrot to do that.

Not only are we in the universe, the universe is in us. I don't know of any deeper spiritual feeling than what that brings upon me.

All tweets are tasty. Any tweet anybody writes is tasty. So, I try to have each tweet not simply be informative, but have some outlook, some perspective that you might not otherwise had.

There is a growing awareness that we're losing our technological competitive edge. I think there's an awareness that we're losing our leadership, and that maybe our self image over the past several decades has been a little bit delusional.
