I was pretty sure the sky was flat, like a cap or a lid or a ceiling. I didn’t think about the sun going up, around, and down; or the moon changing shape; or the constellations moving to different neighborhoods. I was curious about other things, not the sky. The first time I thought about […]
Astronomy
Space is this abstract concept to lots of you. I know so many people, including so many writers, who could not care less about the subject. They are bored, at best, by everything that exists beyond the eggshell-thin layer of this planet’s atmosphere. The wild, kaleidoscopic kingdom of life on this world is enough for […]
Last winter I was staying with friends who have a dark sky. (I don’t have a dark sky and even on clear nights I can hardly see Orion, which makes me sad but I’m used to it.) It was New Year’s Eve and as usual I bugged out early, went up to the guestroom, adjusted […]
For a brief period of my life, the Hubble Space Telescope would shoot me an email with a link about once every two weeks. Then I would click and wait. Then hundreds of thousands of stars would spill across my monitor, lighting up cells in my eyes with photons from a screen from a file […]
Cosmology is timeless, perhaps literally—as this post argued on January 23, 2015. In the 1992 documentary A Brief History of Time, Stephen Hawking describes what we would see if we were observing an astronaut nearing a black hole’s event horizon—the barrier beyond which gravitation is so great that not even light can escape. He invites […]
On October 25, 2010, LWON welcomed a new occasional feature, “Ask Mr. Cosmology,” which invites readers to contribute to a mailbag full of questions about…The Wonders of the Universe! This entry comes from March 26, 2012. Q: Can neutrinos travel faster than light? Mr. Cosmology: Depends what you mean by “light.” Light, as in light rail? Yes. Light, […]
“There is an aspect to this story that is weirder than you can imagine.” That sentence was e-mailed to me by a geologist, Jan Kramers, at the University of Johannesburg in the waning days of 2017. I had e-mailed him about a paper of his in Geochimica et Cosmochmica Acta. The title of the paper […]
I found this ill-cared-for painting from 1976, when I was nine, of a spaceship either taking off or landing on a barren world. This was before Star Wars, but I was well-steeped in forbidden worlds and Star Trek. I dreamed of alien planets, their skies red or green, their landscapes sere and wind-torn. I stared […]
