Dark Matter
You don’t have to detect a particle to know that dark matter is real. “You may hate gravity, but gravity doesn’t care.” –Clayton Christensen In the 1970s, Vera Rubin’s observations showed […]
How Vera Rubin changed the Universe. “Science progresses best when observations force us to alter our preconceptions.” –Vera Rubin Look out at the night sky, and what do you see? […]
How a little knowledge can bring about some huge misconceptions… and how to fix it. “Because philosophy arises from awe, a philosopher is bound in his way to be a lover […]
Gravity is the oldest fundamental force ever discovered. Might it not be fundamental after all? “The whole edifice of modern physics is built up on the fundamental hypothesis of the atomic […]
Something isn’t right about the Universe without something extra. So why can’t scientists agree on what that “extra” thing is? “All we know so far is what doesn’t work.” –Richard Feynman […]
They’re the darkest, most massive things in the Universe. How come they have nothing to do with each other? “All enterprises that are entered into with indiscreet zeal may be pursued […]
And succeeds! “Faced with the choice between changing one’s mind and proving that there is no need to do so, almost everybody gets busy on the proof.” –J. K. Galbraith One […]
A correlation between normal matter and the observed rotation suggests that maybe dark matter isn’t a certainty, after all. “Nothing in the standard cosmological model predicts this, and it is almost […]
It’s the most distant galaxy cluster ever discovered, and it’s exactly in line with our predictions! “These galaxies are among the most massive galaxies in the universe and are believed […]
“Eureka!” is not always as powerful as “that’s what I thought!” “Reality is what kicks back when you kick it. This is just what physicists do with their particle accelerators. […]
The force of empty space isn’t always zero. Here’s how an electromagnetic experiment might be the key to dark energy. “Another very good test some readers may want to look up… […]
