Pure science - this vision of the universe as 15 billion light years across - I am bedazzled and awed by it.

Huston Smith

The universe is a million billion light-years wide, and every inch of it would kill you if you went there. This is the position of the universe with regards to human life.

Martin Amis

The brain is a three pound mass you can hold in your hand that can conceive of a universe a hundred billion light-years across.

Marian Diamond

There is much that science doesn't understand, many mysteries still to be resolved. In a Universe tens of billions of light-years across and some ten or fifteen billion years old, this may be the case forever. We are constantly stumbling on new surprises

Carl Sagan

Images of broken light which dance before me like a million eyes They call me on and on across the universe Thoughts meander like a restless wind inside a letter box They tumble blindly as they make their way across the universe

John Lennon

There are in fact 100 billion galaxies, each of which contain something like a 100 billion stars. Think of how many stars, and planets, and kinds of life there may be in this vast and awesome universe.

Carl Sagan

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.

Neil deGrasse Tyson

You know; when I look at the night sky and I see this enormous splendor of stars and galaxies, I sometimes ask the question, well how many worlds are we talking about? Well do the math, there are about 100 billion galaxies that are in the visible universe and each galaxy in turn contains about 100 billion stars, you multiply and you get about ten billion trillion stars. Well I think it is the height of arrogance to believe that we are alone in the universe, my attitude is that the universe is teaming, teaming with different kinds of life forms

Michio Kaku

Radio Astronomy has added greatly to our understanding of the structure and dynamics of the universe. The cosmic microwave background radiation, considered a relic of the explosion at the beginning of the universe some 18 billion years ago, is one of the most powerful aids in determining these features of the universe.

Robert Woodrow Wilson

To say that the universe exists is silly, because it says that the universe is one of the things in the universe. So there's something wrong with questions like, "What caused the Universe to exist?"

Marvin Minsky

I remind myself that the universe is 15 billion years old, and I'm only 46 years old, so my perspective is sort of limited and fear-based and skewed. So I sort of turn things over to whatever you want to call it - whether it's God, or the universe or the spirit of the universe - and I just sort of turn things over to God and hope that this spirit that has been around for 15 billion years will have a better understanding of how things should be than I do.

When we look out into space, we're looking back in time; the light from a galaxy a billion light-years away, for instance, will take a billion years to reach us. It's an amazing thing. The history is there for us to see. It's not mushed up like the geologic record of Earth. You can just see it exactly as it was.

Margaret Geller

The universe is almost 14 billion years old, and, wow! Life had no problem starting here on Earth! I think it would be inexcusably egocentric of us to suggest that we're alone in the universe.

Neil deGrasse Tyson

Planet Earth is estimated to have a lifetime of nine billion years. And we're right smack in the middle of our lifetime. We've been in the universe for 4.5 billion years. So, that should mean something. We should sort of take a look at where we came from and where we are going.

Miriam Defensor-Santiago

There is no rational reason to doubt that the universe has existed indefinitely, for an infinite time. It is only myth that attempts to say how the universe came to be, either four thousand or twenty billion years ago.

Hannes Alfven

I realized the universe is 15 billion years old and unspeakably complicated. I still love the teachings of Christ, but I also believe that the human condition prevents us from having any true objective knowledge and understanding of the universe.
