“We are incredibly heedless in the formation of our beliefs, but find ourselves filled with an illicit passion for them when anyone proposed to rob us of their companionship.” -James Harvey Robinson The Universe seems to be full of contradictions. On one hand, everywhere we look — in all directions and at all locations —…

“Time takes it all whether you want it to or not, time takes it all. Time bares it away, and in the end there is only darkness.” -Stephen King This story seems to come up every few months. Someone detects a possibly unexpected signal somewhere in the sky — normally correlated to the centers of…

“A single day is enough to make us a little larger or, another time, a little smaller.” -Paul Klee As the time passes for us all, and we age, so too does everything else in the Universe. For an object like a black hole, it has the potential to form, grow or shrink as we move…

“The mind, once expanded to the dimensions of larger ideas, never returns to its original size.” -Oliver Wendell Holmes But it isn’t just your mind that expands as time goes on and you increase your knowledge, but the entire Universe as well. General Relativity, as it turns out, doesn’t leave us with much of a…

“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…

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…
