Curiously, light-loving green plants reject the Sun's green light, reflecting it back at you, which is why they look green.
If the Sun exploded, we wouldn't know about it for 8 minutes and 20 seconds. Light and gravity take that long to reach us. Then we would vaporize.
To believe in a universe as young as 6- or 7,000 years old, is to extinguish the light of most of the galaxy.
In any case, the leading edge of our "on purpose" radio signals is 30 light-years away and, if intercepted, may mend the aliens' image of us based on the radio bubble of our television shows. But this will happen only if the aliens can somehow determine which type of signal comes closer to the truth of who we are, and what our cosmic identity deserves to be.
A supernova is one of the most powerful explosions in the universe. It's so luminous, it can be seen across billions of light years. It releases as much energy in an instant as our sun will produce over its 10-billion-year lifetime.
FM signals and those of broadcast television...travel out to space at the speed of light. Any eavesdropping alien civilization will know all about our TV programs (probably a bad thing), will hear all our FM music (probably a good thing), and know nothing of the politics of AM talk-show hosts (probably a safe thing).
Pretty much every plant and animal alive today is the result of eons of natural cross-breeding.
Every day, I wake up and I say, 'Why... how... did I end up with 1.7 million Twitter followers?' It's freaky to me, every day, but that tells me that there's an appetite out there that had previously been underserved. There's an inner geek in us all, an inner bit of curiosity that people are discovering, and they like it.
'Cosmos' is an occasion to bring everything that I have, all of my capacity to communicate. We may go to the edge of the universe, but we're going to land right on you: in your heart, in your soul, in your mind. My goal is to have people know that they are participants in this great unfolding cosmic story.
I study the universe. It's the second oldest profession. People have been looking up for a long time.
Fortunately, there's another handy driver that has manifested itself throughout the history of cultures. The urge to want to gain wealth. That is almost as potent a driver as the urge to maintain your security. And that is how I view NASA going forward - as an investment in our economy.
If we find life out there, and it's not us, we will deem it not intelligent. But what may be equally as likely is that we find life that's vastly more intelligent than we are. If that's the case, we are putty in their hands.
Pluto's orbit is so elongated that it crosses the orbit of another planet. Now that's... you've got no business doing that if you want to call yourself a planet. Come on, now! There's something especially transgressive about that.
Let's find a new way to think about the entire taxonomy of solar system objects, and not clutch to this concept of 'planet,' which, of course, only ever meant, 'Do you move against the background stars, regardless of what you're made of?'
