When it comes to cosmic perspective, the first name that pops up in our minds is of the great Carl Sagan. Anyone who loves astronomy has at least once, come across the mesmerizing quotes of this man. He is the reason why many children of the twentieth century decided to be a professional astronomer. Sagan was a top rate science populariser, astronomer, astrobiologist, author, cosmologist and astrophysicist. Today, on the occasion of his birth anniversary, here are 10 quotes by Carl Sagan that prove he understood life and universe to a great extent.
Quotes by Carl Sagan:
“The cosmos is within us. We are made of star-stuff. We are a way for the universe to know itself.”
“In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion.”
" Absence of evidence is not evidence of absence.
"The Earth is the only world known so far to harbor life. There is nowhere else, at least in the near future, to which our species could migrate. Visit, yes. Settle, not yet. Like it or not, for the moment the Earth is where we make our stand."
“We are like butterflies who flutter for a day and think it is forever.”
"Science is a way of thinking much more than it is a body of knowledge."
“One glance at a book and you hear the voice of another person, perhaps someone dead for 1,000 years. To read is to voyage through time.”
"If I finish a book a week, I will read only a few thousand books in my lifetime, about a tenth of a percent of the contents of the greatest libraries of our time. The trick is to know which books to read."
"It pays to keep an open mind, not so open that your brains fall out."
"Some 5 billion years from now, after it's burned to a crisp, or even swallowed by the Sun, there will be other worlds and stars and galaxies coming into being -- and they will know nothing of a place once called Earth.”
