I recently had a conversation about the small galaxy that was detected by the Hubble Space Telescope. This tiny galaxy was discovered in the Milky Way’s backyard which makes it sound like you found a new Frisbee behind the garage. But, the backyard of space is endless, or is it?
How do you account for or even imagine the amount of space in all the universe and the amount of space between galaxies, stars, and planets. The Pale-Blue-Dot.png photo taken of earth by the Voyager 1 space probe is said to be a pic of the earth from 4 billion miles away–4 billion miles.
You can barely see the small white fleck, but that’s us, that’s earth in the vastness of space.
My question is: how did this happen? How does space exist? What occurred, what came to pass that resulted in billions of miles of white-speckled space and light-years? Where do our black skies come from?
Carl Sagan titled his 1994 book Pale Blue Dot: A Vision of the Human Future in Space after the photograph. In it, he expresses his thoughts on a deeper meaning of the image: From this distant vantage point, the Earth might not seem of any particular interest. But for us, it’s different. Consider again that dot. That’s here. That’s home. That’s us. On it everyone you love, everyone you know, everyone you ever heard of, every human being who ever was, lived out their lives. The aggregate of our joy and suffering, thousands of confident religions, ideologies, and economic doctrines, every hunter and forager, every hero and coward, every creator and destroyer of civilization, every king and peasant, every young couple in love, every mother and father, hopeful child, inventor and explorer, every teacher of morals, every corrupt politician, every “superstar,” every “supreme leader,” every saint and sinner in the history of our species lived there – on a mote of dust suspended in a sunbeam.
What’s your point of view?
