Dark Matter Haters to the Left

“When you make the finding yourself — even if you’re the last person on Earth to see the light — you’ll never forget it.” -Carl Sagan When we talk about dark matter and its alternatives, we are talking about no less a task than explaining the structure of every large object in the Universe. This…

The Universe is Biased!

“Fortunately for serious minds, a bias recognized is a bias sterilized.” -Benjamin Haydon You might look up at the night sky, at the vast canopy of stars we can see, and ask, exactly, what we’re seeing? Thousands upon thousands of stars, of course, even with just your naked eye. These stars come in all sorts…

What Dark Matter’s Alternatives Must Do

“The only relevant test of the validity of a hypothesis is comparison of prediction with experience.” -Milton Friedman Dark matter is one of the most important components of the Universe today. And yet in the public’s eye, almost no one accepts it the way, say, the Big Bang is accepted. But it should be, and…

Why Dark Matter Rules Mini-Galaxies!

“A new scientific truth does not triumph by convincing its opponents and making them see the light, but rather because its opponents eventually die, and a new generation grows up that is familiar with it.” -Max Planck (For Alan L., from the comments on this post.) When you look out at the night sky, with…

There lies the eternal distinction between good and evil.” -Gerard De Nerval (For Rich C. and Sili, for their questions on this post.) The humble hydrogen atom — one proton…

“[I]f there were no light in the universe and therefore no creatures with eyes, we should never know it was dark. Dark would be without meaning.” -C.S. Lewis (For readers Mu and Bjoern.) I’ve told you the entire history of the Universe, from before the Big Bang into the far distant future, and yet many…

“We are just an advanced breed of monkeys on a minor planet of a very average star. But we can understand the Universe. That makes us something very special.” -Stephen Hawking You’re probably familiar with the standard picture of our Universe. You’ve heard it all before: that the Universe we know of — stars, planets,…

Dark Energy Confirmed Again!

“We all need to look into the dark side of our nature – that’s where the energy is, the passion. People are afraid of that because it holds pieces of us we’re busy denying.” -Sue Grafton No, not the dark side of our nature, just the dark side of nature! Because if all our Universe…

“You still don’t get it, do you? He’ll find her! That’s what he does! That’s ALL he does! You can’t stop him!” -Kyle Reese, the Terminator Now that we’ve all survived Judgment Day, we can stop looking for ways to stop the Terminators, and go back to the search for dark matter. Let’s back up…
