Cosmic Expansion Quotes

If the rate of expansion one second after the Big Bang had been smaller by even one part in a hundred thousand million million, it would have recollapsed before it reached its present size. On the other hand, if it had been greater by a part in a million, the universe would have expanded too rapidly for stars and planets to form.

We don't want to conquer the cosmos, we simply want to extend the boundaries of Earth to the frontiers of the cosmos.

There are millions of stars out there. It is difficult to think that life does not exist in any one of them.

What was done is measure directly, with exquisitely sensitive instruments, gravitational waves predicted about 100 years ago by Albert Einstein. These waves are a new way to study the universe and are expected to have significant impact on astronomy and astrophysics in the years ahead.

In the beginning there was nothing, which exploded.

Every field of astrophysics - whether it's our local neighborhood of planets, nearby stars and their attendant planets, galaxies, clusters of galaxies, out to the edge of the universe - every field has questions that are awaiting the power of Hubble.

Even these stars, which seem so numerous, are as sand, as dust - or less than dust - in the enormity of the space in which there is nothing.

Humanity is not forever chained to this planet.

Universe consists of frozen light.

Far from feeling dwarfed by the vast reaches and energy of the cosmos, what we really learn is that we are the most remarkable and complicated product of cosmic evolution, and our potential is unlimited.

The extension of life beyond Earth is the most important thing we can do as a species.

Even to make the first cell possible, stellar space required to be swept of matter, suns must needs be broken up, and planets cool, the agents of geology labour millennium after millennium at the unfinished earth to prepare a material resting-place for the coming guest. Consider all this, and judge if Creation could have a sublimer meaning, or the Human Race possess a more splendid genesis.

And what I was feeling was the wonder Of being more than me, of being more Than mere here and now allowed I had become a shining star, a burning nova Exploded with love Flying through an endlessly Expanding universe Away from the me that was Toward a me that is beyond Understanding.

Mars is the next frontier, what the Wild West was, what America was 500 years ago. It's time to strike out anew....Mars is where the action is for the next thousand years....The characteristic of human nature, and perhaps our simian branch of the family, is curiosity and exploration. When we stop doing that, we won't be humans anymore. I've seen far more in my lifetime than I ever dreamed. Many of our problems on Earth can only be solved by space technology....The next step is in space. It's inevitable.

I have a much easier time imagining how we would understand the big bang, even though we can't do it yet, than I can imagine understanding consciousness.

Scientists estimate the universe unfolded from its state of infinite destiny* - a moment commonly referred to as "the big bang" - approximately 1.3-2 x 10^10 years ago. *Typo: "destiny" should read "density.

I can feel the universe expanding and making things be further apart.

There was a time when 'universe' meant 'all there is.' Everything. The whole shebang. The notion of more than one universe, more than one everything, would seemingly be a contradiction in terms.

We need to spread out now in the universe. I think in 100 years we'll be living on other planets.

The History Of The Universe In Three Words CHAPTER ONE Bang! CHAPTER TWO sssss CHAPTER THREE crunch. THE END

Who among us has never looked up into the heavens on a starlit night, lost in wonder at the vastness of space and the beauty of the stars?

The universe will finally become a ball of radiation, becoming more and more rarified and passing into longer and longer wave-lengths. The longest waves of radiation are Hertzian waves of the kind used in broadcasting. About every 1500 million years this ball of radio waves will double in diameter; and it will go on expanding in geometrical progression for ever. Perhaps then I may describe the end of the physical world as-one stupendous broadcast.

Asking what was before the Big Bang is like asking what is North of the North Pole. It is not a defined question and has no meaning.

The Earth is a very small stage in a vast cosmic arena.

No one planet can tell us everything about the universe, but Neptune seems to hold more than its share of information about the formation of our own solar system - as well as the solar systems beyond.
