Carl Sagan Quotes

Space is almost infinite. As a matter of fact, we think it is infinite.

The universe is a big place, perhaps the biggest.

The universe is a great mystery.

There are at least as many galaxies in our observable universe as there are stars in our galaxy.

There's a bigger universe at hand.

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.

It bears mentioning that the Milky Way is only one of 150 billion galaxies visible to our telescopes - and each of these will have its own complement of planets.

Space is certainly something more complicated than the average person would probably realize. Space is not just an empty background in which things happen.

I am very interested in the Universe - I am specialising in the Universe and all that surrounds it.

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

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?

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.

Put three grains of sand inside a vast cathedral, and the cathedral will be more closely packed with sand than space is with stars.

Who are we? We find that we live on an insignificant planet of a humdrum star lost in a galaxy tucked away in some forgotten corner of a universe in which there are far more galaxies than people.

At night, when the sky is full of stars and the sea is still you get the wonderful sensation that you are floating in space.

I'm not really into sci-fi movies, but I'm into the science of space a lot. I love astronomy and thinking about the nothingness of the everythingness of space.

Space is a laboratory, an experiment in all forms of all things, an infinity of possibilities, properties, and places that cry out for investigation and exploration.

We are discovering what the universe is really like, and it is totally magnificent, and one can only be inspired and awestruck by what we find.

The Hubble Space Telescope is more than remarkable. It has answered just so many of those fundamental questions that people have been asking about the cosmos since people were able to ask questions.

There is no stronger case for the motivational power of real science than the discoveries that come from the Hubble Space Telescope as it unravels the mysteries of the universe.

Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the drug store, but that's just peanuts to space.

Astronomers still can't decide what the shape of our universe is. Is it closed and finite, which is to say, is there a countable tally of all the galaxies that exist, even beyond the ones we can see? Or is it infinite? The latter possibility is still on the table.

Near the sun is the center of the universe.

The universe extends beyond the mind of man, and is more complex than the small sample one can study. God cannot be reduced to a sample for analysis.

I always think of space-time as being the real substance of space, and the galaxies and the stars just like the foam on the ocean.
