“It turned out that nature was very kind, and there appear to be many of these black holes in the Universe and we were lucky enough to see one.” -Dave Reitze, executive director of LIGO On September 14th, 2015, just days after turning on, the twin Advanced LIGO detectors detected the first gravitational wave signature:…

“That what wrong with the media today. All they have is questions, questions, questions. They never have cookies.” -Cookie Monster There are lots of things to worry about in this Universe, including falling into a black hole. But unless you happen to fall directly into the event horizon, an incredibly small region of space for…

“Not only does God play dice, but… he sometimes throws them where they cannot be seen.” -Stephen Hawking The New York Times ran an article on Stephen Hawking promising there was a possible escape route from a black hole, after all. In the text, Hawking asserts, “They are not the eternal prisons they were once…

“What’s really exciting is what comes next. I think we’re opening a window on the universe — a window of gravitational wave astronomy.” -Dave Reitze On September 14, 2015, LIGO directly detected gravitational waves for the first time, from the inspiral-and-merger of two quite massive black holes. Despite the fact that no electromagnetic radiation signal…

“[The black hole] teaches us that space can be crumpled like a piece of paper into an infinitesimal dot, that time can be extinguished like a blown-out flame, and that the laws of physics that we regard as ‘sacred,’ as immutable, are anything but.” -John Wheeler Dark matter is one of the biggest mysteries in…

“If I can’t make it through one door, I’ll go through another door – or I’ll make a door. Something terrific will come no matter how dark the present.” -Rabindranath Tagore Time continues marching on here at Starts With A Bang, just as it does everywhere. My Patreon supporters have stepped up their game, and we’re just…

“A single day is enough to make us a little larger or, another time, a little smaller.” –Paul Klee When it comes to normal matter, dark matter is a bit of a puzzle. Other than through the gravitational force, there’s no way we’ve yet figured out to make it interact. Try and collide it with…

“When I was in high school, I was certain that being an astronaut was my goal. It was a very important time — Sally Ride was making her first flight into space and she had a real impact on me. Those ‘firsts’ kind of stick in your head and really become inspirations for you.” Karen Nyberg,…

“Even if the Fermi detection is a false alarm, future LIGO events should be monitored for accompanying light irrespective of whether they originate from black hole mergers. Nature can always surprise us.” -Avi Loeb Ever since LIGO first announced the direct detection of gravitational waves from two merging black holes, the physics and astronomy community…

“Maybe that is our mistake: maybe there are no particle positions and velocities, but only waves. It is just that we try to fit the waves to our preconceived ideas of positions and velocities. The resulting mismatch is the cause of the apparent unpredictability.” -Stephen Hawking Black holes are the densest, most compact objects in…
