Pale Blue Dot, a bestselling book by the late Carl Sagan, seems to be extremely popular with Internet atheists. At
YouTube, we can find a video of the same title, with a narration by Sagan, in which he describes our planet as "a mere point in a vast, encompassing cosmos." And we see footage taken by one of the Voyager spacecraft that shows the Earth as a mere point. Specifically, a pale blue dot.
Internet atheists urge all of us to think about this, to have our minds blown by the realization that our world doesn't count for squat in the cosmic scheme.
Where else would we encounter such wisdom? Certainly not in the past. Not in, say, textbooks of the nineteenth century. Here, for example, is a quote from Joel Dorman Steele's very popular text
The Story of the Stars: New Descriptive Astronomy, copyright 1869 and 1884. Try to bear with the antiquated point of view:
"We are humbled as we gaze upon the infinity of suns, and strive to comprehend their enormous distances, and their magnificent retinue of worlds."
Steele goes on to make the following claims about Earth--that the planet "is in motion, flying through its orbit with inconceivable velocity; that it is not fixed, but hangs in space, held by an invisible power of gravitation which it cannot evade; that it is small and insignificant beside the mighty globes that so gently shine upon us in the far-off sky; that, in fact, it is only one atom in a universe of worlds, all firm and solid, and all, perhaps, equally fitted to be the abode of life."
Ha! Hilarious, isn't it, the contrast between 19th and 20th-century views of the cosmos, no? And Steele was a believer, no less--his text contains many mentions of God and creation.
How far we've come. From the Earth as "one atom in a universe of worlds" to "a mere point in a vast, encompassing cosmos." How far we've advanced in our understanding of Earth's place in the scheme of things.
Again, it's easily explained--Steele was a believer, Sagan was not. Hence, "one atom in a universe of worlds" vs. the infinitely more enlightened "mere point in a vast, encompassing cosmos."
It's a good thing we evolved past the 19th century, what with the silly popular notions people labored under.
We close with a hilarious illustration called "Earth in Space," from the Steele volume. How comically this contrasts with Sagan's image of a small, insignificant body in the loneliness of things:
