“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…

“Twinkle, twinkle quasi-star. Biggest puzzle from afar. How unlike the other ones. Brighter than a billion suns. Twinkle, twinkle, quasi-star. How I wonder what you are.” -George Gamow One of the most interesting classes of objects in the entire sky is one that’s invisible to the naked eye, yet appears brighter than anything else in…

“Never look down to test the ground before taking your next step; only he who keeps his eye fixed on the far horizon will find the right road.” -Dag Hammarskjold One of the great discoveries of the past few decades was that of a supermassive black hole at the center of our Milky Way. No…

“It’s not the job of the theorist to defend his model at all costs!” – Joel Primack One of the more puzzling phenomena in our quantum Universe is that of entanglement: two particles remain in mutually indeterminate states until one is measured, and then the other — even if it’s across the Universe — is…

We live in a Universe full of galaxies, supermassive black holes, and violence. The violence is particularly relevant here, because every so often, these galaxies merge, and if they each contain a supermassive black hole, the gravitational wave “ripples” that get sent through space will literally shake and affect everything that’s in them. If you…

Black holes and academic walls (Synopsis)

100 years ago, Einstein put forth his General Theory of Relativity, and 99 years ago, Karl Schwarzschild came up with the mathematical solution describing a black hole, a solution we now know is not only physically valid, but one that has many examples all across the Universe. Yet when you consider quantum physics, the matter…

“I was strongly encouraged by a science teacher who took an interest in me and presented me with a key to the laboratory to allow me to work whenever I wanted.” -Frederick Reines, discoverer of the first neutrino That kind of education is irreplaceable, and at Starts With A Bang we do our best to bring the…
