“Other galaxies like Andromeda are shooting these ‘spitballs’ at us all the time.” -James Guillochon, coauthor on the new study Imagine you’re a star passing too close to a black hole. What’s going to happen to you? Yes, you’ll be tidally disrupted and eventually torn apart. Some of the matter will be swallowed, some will…

“It’s the first time the universe has spoken to us through gravitational waves, up to now we’ve been deaf to them.” -Dave Reitze No doubt about it: the greatest science advance of 2016 was the end of the century-long wait for the first direct detection of gravitational waves. Not only were we able to detect…

“Even with all the collected data we cannot say with 100% certainty that the ASASSN-15lh event was a tidal disruption event. But it is by far the most likely explanation.” -Giorgos Leloudas Last year, a record-shattering event occurred: we saw the brightest supernova ever observed in the Universe. It outshone the previous record holder by…

“The bedrock nature of space and time and the unification of cosmos and quantum are surely among science’s great ‘open frontiers.’ These are parts of the intellectual map where we’re still groping for the truth – where, in the fashion of ancient cartographers, we must still inscribe ‘here be dragons.’” -Martin Rees In 2015, LIGO…

“I’ll never, ever be full. I’ll always be hungry. Obviously, I’m not talking about food.” -Dwayne ‘The Rock’ Johnson Only a very small percentage of galaxies have active supermassive black holes. While the black holes themselves are common, they only rarely feed, gaining a huge influx of matter to accelerate and send jets and other…

“I think there are a number of experiments that are thinking about how you could look in different frequency bands, and get a glimpse of the primordial gravitational wave background. I think that would be really revolutionary, because that would be your first glimpse at the very first instant of our Universe.” -Dave Reitze, LIGO’s…

“All enterprises that are entered into with indiscreet zeal may be pursued with great vigor at first, but are sure to collapse in the end.” -Tacitus Dark matter makes up the overwhelming majority of mass in the Universe. With five times as much of it as there is normal matter, and the fact that it…

“Man is something that shall be overcome. Man is a rope,tied between beast and overman – a rope over an abyss.What is great in man is that he is a bridge and not an end.” -Friedrich Nietzsche There are only two types of singularities that General Relativity predicts the existence of in our Universe: one…

“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 A black hole is a region of space that’s got so much mass in such a small volume that the escape velocity within a specific…

“For something to collapse, not all systems have to shut down. In most cases, just one system is enough.” -Robert Kiyosaki Do supermassive black holes form from the merger and growth of many smaller black holes, falling towards a cluster/galactic center where they find one another and grow into a behemoth? Or is there a…
