“People who work every day are kind of scared of things they don’t understand.” -Young Jeezy From Mercury out to Neptune, most of the worlds in the Solar System have moons, with a hitherto discovered population of around 200 known ones. Yet despite all of it, we don’t know of a single instance of a…

“The black holes collide in complete darkness. None of the energy exploding from the collision comes out as light. No telescope will ever see the event.” -Janna Levin Whenever there’s a catastrophic, cataclysmic event in space, there’s almost always a tremendous release of energy that accompanies it. A supernova emits light; a neutron star merger…

“No matter what technique you use, you should get the same value for the expansion rate of the universe today.” -Ben Hoscheit When you think of the Universe on the largest scales, you likely think of galaxies grouped and clustered together in huge, massive collections, separated by enormous cosmic voids. But there’s another kind of…

“Black holes are the seductive dragons of the universe, outwardly quiescent yet violent at the heart, uncanny, hostile, primeval, emitting a negative radiance that draws all toward them, gobbling up all who come too close…these strange galactic monsters, for whom creation is destruction, death life, chaos order.” -Robert Coover For the third time since it…

“Unless one says goodbye to what one loves, and unless one travels to completely new territories, one can expect merely a long wearing away of oneself and an eventual extinction.” -Jean Dubuffet In the far future, all the galaxies within our Local Group will merge together, with enough gas and stellar material to form trillions…

“Where we’re going, we won’t need eyes to see.” -Sam Neill, Event Horizon Are event horizons real? With data taken from around a dozen observatories earlier this year, simultaneously, the Event Horizon Telescope is poised to put together the first-ever direct image of the black hole at the center of our galaxy Sagittarius A*. If…

“If you’re puzzled by what dark energy is, you’re in good company.” -Saul Perlmutter We normally assume that the fundamental constants of the Universe are actually constant, but they don’t have to be that way. They could vary in space, in time, or with the energy density of the Universe, in principle. Before believing in…

“N6946-BH1 is the only likely failed supernova that we found in the first seven years of our survey. During this period, six normal supernovae have occurred within the galaxies we’ve been monitoring, suggesting that 10 to 30 percent of massive stars die as failed supernovae.” -Scott Adams Everyone knows the recipe for a black hole:…

“The Edge… there is no honest way to explain it because the only people who really know where it is are the ones who have gone over.” -Hunter S. Thompson When we look at the nearby Universe, it looks a lot like we, ourselves, appear. Nearby galaxies are similar in structure to our own; the…

“First Rate People hire first rate people. Second rate people hire third rate people.” -Hermann Weyl So, here we are, encountering one another on the internet. There’s a really good chance that this is because you have some interest in space, science, astronomy, astrophysics, or some related area. Although I am an astrophysicist with a…
