“The surface of the Earth is the shore of the cosmic ocean. On this shore, we've learned most of what we know. Recently, we've waded a little way out, maybe ankle-deep, and the water seems inviting.” — Carl Sagan 🎥 @wonderofscience.bsky.social

“Science is a way of thinking much more than it is a body of knowledge.” — Carl Sagan
"Look again at that dot. That's here. That's home. That's us."
We are the legacy of 15 billion years of cosmic evolution. We have a choice: We can enhance life and come to know the universe that made us, or we can squander our 15 billion-year heritage in meaningless self-destruction. ~ Carl Sagan
Think of the endless cruelties visited by the inhabitants of one corner of the dot on scarcely distinguishable inhabitants of some other corner of the dot. How frequent their misunderstandings, how eager they are to kill one another, how fervent their hatreds.
The very first clip of COSMOS—this is where it all began. A voyage from the shores of Earth's oceans to the infinite expanses of the Milky Way, Andromeda, and beyond. Thank you, Carl, for taking us on this journey. We remain forever in your debt.

Albert Einstein died on this day, April 18, 1955. It is incredible to hear Albert Einstein explain his famous formula, E=mc².
"There is perhaps no better demonstration of the folly of human conceits than this distant image of our tiny world. To me, it underscores our responsibility to deal more kindly with one another, and to preserve and cherish the pale blue dot, the only home we've ever known." - Carl Sagan
The nitrogen in our DNA, the calcium in our teeth, the iron in our blood, the carbon in our apple pies were made in the interiors of collapsing stars. We are made of starstuff. ~ Carl Sagan, Cosmos

“Astrologers cannot even agree among themselves what a given horoscope means.” ~ Carl Sagan
This dim and distant world is the farthest planet from the Sun, about 30 times farther away than planet Earth. Details of the complex ring system are seen here for the first time since Neptune was visited by the Voyager 2 spacecraft in August 1989. Image Credit: NASA, ESA, CSA, STScI, NIRCam

Skeptical scrutiny is the means, in both science and religion, by which deep insights can be winnowed from deep nonsense.

To live in the hearts of those we leave behind is to never die.
