“There will be days when we lose faith. Days when our allies turn against us…but the day will never come that we forsake this planet and its people.” ―Optimus Prime There was too much to simply keep it to a single article a day this week here at Starts With A Bang! The dynamic duo of Megan…

“It’s becoming clear that in a sense the cosmos provides the only laboratory where sufficiently extreme conditions are ever achieved to test new ideas on particle physics. The energies in the Big Bang were far higher than we can ever achieve on Earth. So by looking at evidence for the Big Bang, and by studying…

“Presently thought to be the most powerful explosions in nature… their sources have only recently been localized by observations of associated afterglows in X-rays, visible light, and radio waves, delayed in that order.” -Richard Matzner, on the dictionary entry for Gamma Ray Burst It seems like an eternity ago, but it’s been under two years…

“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 So, you’ve got a black hole in the Universe,…

“Our first priority was making sure we weren’t fooling ourselves.” -Keith Riles, LIGO team member When LIGO announced their first discovery of a black hole-black hole merger, it came as a surprise to almost everyone. The shocking part wasn’t that LIGO had seen merging black holes, but that they were discovered to be so massive.…

“The years of searching in the dark for a truth that one feels but cannot express, the intense desire and the alternations of confidence and misgiving until one breaks through to clarity and understanding, are only known to him who has himself experienced them.” -Albert Einstein In 2015, for the very first time, gravitational waves…

“Ultramassive black holes — that is, black holes with masses exceeding 10 billion solar masses — are probably not rare; several and even dozens of these colossal black holes may exist.” -Julie Hlavacek-Larrondo The largest black hole in the Universe was a shocker when it was first discovered. At 40 billion solar masses, it certainly is…

“Nobody ever did, or ever will, escape the consequences of his choices.” -Alfred A. Montapert So you’re passing by a black hole in a massive, fast-moving spaceship, and you want to do an experiment: you tether a small mass outside of the ship and let it fall into the black hole, just allowing it the…

“We hope that interested people will repeat our calculations and will make up their own minds regarding the significance of the results. It is obvious that “belief” is never an alternative to “understanding” in physics.” -J. Creswell et al. Three times now, the LIGO collaboration has produced very strong evidence that black hole pairs, from…

“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, executive director of LIGO It revolutionized our view of the Universe when the LIGO annoucements – and we’re up to three, now – came out. They indicated the direct detection…
