One cold night a couple of weeks ago, my family and I bundled up to bike out to a park in one of Seattle’s northern suburbs. We have a routine for such trips after all these years. First we layer, and then we bedeck our bikes with lights: front lights, back lights, hub lights, even […]
The Cosmos
Time again to reach into the “Ask Mr. Cosmology” mailbag and see what readers want to know about . . . The Wonders of the Universe! Q: Does the word “creation” imply a Creator? Mr. Cosmology: No, thank God. Q: What does Mr. Cosmology think of the theorists who argue for the anthropic principle? Mr. Cosmology: They’re […]
This essay originally ran in 2011. Back then, the Hubble Space Telescope was the exemplar of non-Earth astronomical observation. Its successor, the James Webb Space Telescope, launched in December 2021. This anecdote, however, might be timeless. In 1984, David Soderblom was a new hire at the Space Telescope Science Institute in Baltimore, and one day […]
Given the choice, I wouldn’t be a bear, though it’s tempting to skip this dark season and live off my fat. Far below the metabolic plane of sleep, my body would be as cold as death to the touch. Parts of the brain that dart about in REM sleep are turned off, brain functions reduced […]
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, […]
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 […]
By the time you read this post, 2020 will have already arrived at the South Pole. Even if you read it the instant it pops up on the Internet, at 7 a.m. EST December 31, 2019, the New Year will already be an hour old. You don’t have to go to the South Pole to […]
