“Nobody ever did, or ever will, escape the consequences of his choices.” -Alfred A. Montapert You might not think of falling into a black hole as a choice, but in the case of this week’s Ask Ethan, someone is choosing to explore exactly that! Imagine, if you will, taking a solid object that’s completely outside of an…

“On a cosmic scale, our life is insignificant, yet this brief period when we appear in the world is the time in which all meaningful questions arise.” -Paul Ricoeur What you see is what you get, except when it isn’t. We’re all familiar with Hubble’s law, or the notion that the Universe is expanding, and…

“Try to imagine what it will be like to go to sleep and never wake up… now try to imagine what it was like to wake up having never gone to sleep.” -Alan Watts Neutron star matter is the stuff of legends: it’s the densest three-dimensional material to exist in our Universe. With a density…

“The moon was like this awesome, romantic, mysterious thing, hanging up there in the sky where you could never reach it, no matter how much you wanted to. But you’re right. Once you’re actually here, it’s just a big, dull rock.” -Futurama Oh, but the big dull rocks are fascinating in their own right. Especially, mind…

“Henceforth space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality.” -Hermann Minkowski When you think of waves, chances are you think of some type of pressure wave moving through a medium, like sound or water…

“Even in hindsight, I would not change one whit of the Voyager experience. Dreams and sweat carried it off. But most of all, its legacy makes us all Earth travelers among the stars.” -Charley Kohlhase It’s a taxing enough task to launch something off the surface of the Earth, escaping our planet’s gravity and finding…

Impending Doom (Synopsis)

“From an incandescent mass we have originated, and into a frozen mass we shall turn. Merciless is the law of nature, and rapidly and irresistibly we are drawn to our doom.” -Nikola Tesla Stability: it’s the hallmark of the Solar System. The motions of all the planetary bodies are regular and periodic. The paths of…

“But even when the moon looks like it’s waning…it’s actually never changing shape. Don’t ever forget that.” -Ai Yazawa You’ve seen the iconic crescent, quarter, gibbous and full phases for yourself, and probably even an eclipse or two. For millennia, the Moon has fascinated, delighted and mystified observers of the skies. Less than 50 years…

“I think if I had to choose, I would rather have gravity instead of zero gravity. It’s fun for a while, but I’d rather live on Earth.” -Kevin A. Ford By now, you’ve probably had a lot of opportunities to think about what holds our Universe together: the incredible force of gravitation. Although it’s the…
