“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…

Sure, the Big Bang is great. Going back to very early times, it tells us the Universe was in a hot, dense state, where even the possibility of forming neutral atoms was impossible due to the incredible energies of the Universe at that time. The patterns of fluctuations that are left over from that time…

The Strangest Theory We Know Is True (Synopsis)

When it comes to physics, there sure are some strange theories — and even stranger phenomena — out there. The notion that particles don’t have fixed, intrinsic properties that are simultaneously measurable can only be described as weird, and the fact that you can add as much energy as you want to a particle but…

“I was confided to your loyalty and accepted by your treason; you offer my death to those to whom you had promised my life. Do you know who it is you are destroying here? It is yourself.” –Victor Hugo So those of you who’ve been paying attention may have just heard that we’ve mapped out…

“To be loyal to myself is to allow myself to grow and change, and challenge who I am and what I think. The only thing I am for sure is unsure, and this means I’m growing, and not stagnant or shrinking.” ‐Jarod Kintz But for the Universe, although it’s constantly changing, growing in a gravitational sense…

Is our Universe left-handed? (Synopsis)

“Since the beginning of physics, symmetry considerations have provided us with an extremely powerful and useful tool in our effort to understand nature. Gradually they have become the backbone of our theoretical formulation of physical laws.” –Tsung-Dao Lee We normally think of the Universe as being symmetric, in the sense that no one direction, location…

“Art has a double face, of expression and illusion, just like science has a double face: the reality of error and the phantom of truth.” –Publilius Syrus Out in the depths of space, objects range from the incredibly small and low mass to the huge and super-heavy, shrinking down again for the most ultra-massive objects…
