We are making music for the human race, and even beings from other galaxies are welcome to vibe with us.

If you take a galaxy and try to make it bigger, it becomes a cluster of galaxies, not a galaxy. If you try to make it smaller than that, it seems to blow itself apart.

There must be enormous numbers of planets around the stars in the many galaxies in our observable universe. We may be sure that wonderful things are happening on these planets that the human race never will observe.

The universe is very big - there's about 100,000 million galaxies in the universe, so that means an awful lot of stars. And some of them, I'm pretty certain, will have planets where there was life, is life, or maybe will be life. I don't believe we're alone.

I am undecided whether or not the Milky Way is but one of countless others all of which form an entire system. Perhaps the light from these infinitely distant galaxies is so faint that we cannot see them.

Astronomers can look back in time. We can look at things as they used to be. We have an idea there was a Big Bang explosion 13.7 billion years ago. We have a story of how galaxies and stars were made. It's an amazing story.

The James Webb Space Telescope was specifically designed to see the first stars and galaxies that were formed in the universe.

The James Webb Space Telescope was specifically designed to see the first stars and galaxies that were formed in the universe. So we're gonna see the snapshot of when stars started. When galaxies started. The very first moments of the universe. And my bet? There's gonna be some big surprises.

I have to believe there's some other life force out there. I don't know in what form. But we can't have all these galaxies and universes without something going on.

Philosophically, the universe has really never made things in ones. The Earth is special and everything else is different? No, we've got seven other planets. The sun? No, the sun is one of those dots in the night sky. The Milky Way? No, it's one of a hundred billion galaxies. And the universe - maybe it's countless other universes.
