“And no one showed us to the land And no one knows the where’s or why’s But something stirs and something tries And starts to climb towards the light” –Pink Floyd, Echoes It’s pretty difficult to imagine, but a little over 300 years ago, a supernova — a dying, ultramassive star — exploded, giving rise…

“I just think too many nice things have happened in string theory for it to be all wrong. Humans do not understand it very well, but I just don’t believe there is a big cosmic conspiracy that created this incredible thing that has nothing to do with the real world.” –Ed Witten So the cat…

“It is by going down into the abyss that we recover the treasures of life. Where you stumble, there lies your treasure.” –Joseph Campbell When we look at the centers of galaxies, it’s no surprise that there are large black holes there, millions or even billions of times the mass of the Sun. As we…

Out there in the Universe, black holes are some of the most extreme examples of physics in the Universe. Space is curved tremendously, there’s an incredible concentration of energy all in one, singular point, and everything that occurs, in theory, outside of the event horizon can be seen in our Universe. But what if one…

“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…

“There is, I believe, in every disposition a tendency to some particular evil, a natural defect, which not even the best education can overcome.” “And your defect is a propensity to hate everybody.” “And yours… is wilfully to misunderstand them.” –Jane Austen Every time we go to higher and higher energies in our particle accelerators,…

“According to the special theory of relativity nothing can travel faster than light, so that if light cannot escape, nothing else can either. The result would be a black hole: a region of space-time from which it is not possible to escape to infinity.” –Stephen Hawking The idea of a black hole, of a region…

“A single day is enough to make us a little larger or, another time, a little smaller.” –Paul Klee As the time passes for us all, and we age, so too does everything else in the Universe. For an object like a black hole, it has the potential to form, grow or shrink as we move…

“Es ist immer angenehm, über strenge Lösungen einfacher Form zu verfügen.” (It is always pleasant to have exact solutions in simple form at your disposal.) –Karl Schwarzschild The Universe is a vast and complex place, full of a diversity of structure from the smallest scales to the largest. And yet, by many accounts, it’s a…

“And then you wake up, only to see that the darkness has gone, the light now truly makes you feel vulnerable and you wonder why this darkness did not wish you well and why did it leave you so sudden, without revealing the answers you were looking for.” –Chirag Tulsiani “You’ve seen one, you’ve seen…
