“When a train goes through a tunnel and it gets dark, you don’t throw away the ticket and jump off. You sit still and trust the engineer.” -Corrie Ten Boom When you look out into the Universe at distant galaxies, at clusters of galaxies or at the Universe on the largest scales, what you see is…

Whether you’ve been coming around to Starts With A Bang for years or whether you just discovered us a few weeks ago, chances are you’ve heard us take on the issue of dark matter — whether it exists and, if so, what its properties are — and how we think we know that. And while every…

Today’s article comes courtesy of Sabine Hossenfelder. Sabine is an assistant professor for high energy physics at Nordita, Stockholm. She writes a blog called Backreaction and tweets as @skdh. Dark matter is one of the most elusive and puzzling entities in our Universe today. We have plenty of indirect evidence for it, but one of…

“Two qualities are indispensable: first, an intellect that, even in the darkest hour, retains some glimmerings of the inner light which leads to truth; and second, the courage to follow this faint light wherever it may lead.” -Carl von Clausewitz You’ve been hanging around here long enough that you know all about dark matter’s successes,…

“Science casts a long black shadow back over who we think we are, and where it falls the temperature falls with it. Its touch is chilly and unforgiving.” -Richard K. Morgan Here on Earth, when we’re dealing with normal matter, it’s relatively easy to measure the temperature of something. Even if you don’t have a thermometer…

“There are things known and there are things unknown, and in between are the doors of perception.” -Aldous Huxley From tiny, laser-light wavelengths to dark skies to dark matter on the largest scales in the Universe, it’s been quite a week at the main Starts With A Bang collection over at Medium. New this week, we’ve…

“Science progresses best when observations force us to alter our preconceptions.” -Vera Rubin Yesterday, we took an amazing look at a finding that looks like it rules out Dark Matter’s #1 Competitor: TeVeS. But if that’s true — and the Universe must be full of dark matter — just what exactly do we know about this…

“The discrepancy between what was expected and what has been observed has grown over the years, and we’re straining harder and harder to fill the gap.” -Jeremiah P. Ostriker When it comes to the Universe, and the structure in it, from galaxies to groups to clusters to the grand cosmic web on the largest scales,…

Ask Ethan #17: The Burden of Proof

“Never waste your time trying to explain who you are to people who are committed to misunderstanding you.” -Dream Hampton Perhaps no word in the English language generates as much misunderstanding as the word theory. In scientific circles, this word has a very specific meaning that’s different from everyday use, and — as a theoretical…

The Largest Trainwrecks in the Universe

“Where you used to be, there is a hole in the world, which I find myself constantly walking around in the daytime, and falling in at night. I miss you like hell.” -Edna St. Vincent Millay It was just a little while ago that we were all speculating wildly — and optimistically — about Comet…
