“It is morally as bad not to care whether a thing is true or not, so long as it makes you feel good, as it is not to care how you got your money as long as you have got it.”

American astronomer and science communicator of the mid-to-late 20th century, Carl Sagan made complex cosmic concepts accessible to the public through his books and television series. He championed scientific skepticism and the search for extraterrestrial life, blending rigor with poetic clarity to inspire wonder about humanity’s place in the universe.
