The Rise and Fall of Supersymmetry

“Supposedly she’d died, but here she was again–somewhat changed, but you couldn’t kill her. Not when the truest part of her hadn’t even been born.” -Denis Johnson Over the past 100 years, our picture of the Universe has changed dramatically, on both the largest scales and the smallest. On the large-scales, we’ve gone from a…
What Makes Up The Universe?
Posted by Ethan on April 18, 2013 
“The cosmos is all that is or ever was or ever will be. Our feeblest contemplations of the Cosmos stir us—there is a tingling in the spine, a catch in the voice, a faint sensation, as if a distant memory, or falling from a height. We know we are approaching the greatest of mysteries.” -Carl…
What Matters about Dark Matter?

“A cosmic mystery of immense proportions, once seemingly on the verge of solution, has deepened and left astronomers and astrophysicists more baffled than ever. The crux… is that the vast majority of the mass of the universe seems to be missing.” -William J. Broad Three classic observations — the Hubble expansion of the Universe, the…
It’ll take a lot more than AMS to find Dark Matter

“On what can we now place our hopes of solving the many riddles which still exist as to the origin and composition of cosmic rays?” -Victor Francis Hess We’ve come a tremendously long way in our understanding of the Universe, but there are plenty of mysteries still to be revealed. Way back in the late…
What The Entire Universe Is Made Of, Thanks to Planck!
Posted by Ethan on March 21, 2013 
“Much later, when I discussed the problem with Einstein, he remarked that the introduction of the cosmological term was the biggest blunder he ever made in his life. But this “blunder,” rejected by Einstein, is still sometimes used by cosmologists even today, and the cosmological constant denoted by the Greek letter Λ rears its ugly…
The Worst Kind of Science Hype
Posted by Ethan on February 20, 2013 
“We’ve learned from experience that the truth will come out. Other experimenters will repeat your experiment and find out whether you were wrong or right. Nature’s phenomena will agree or they’ll disagree with your theory. And, although you may gain some temporary fame and excitement, you will not gain a good reputation as a scientist…
Why the Universe needs Dark Matter (and not MOND) in one graph

The Last Refuge of a Science-Denying Scoundrel

“Every man has a right to utter what he thinks truth, and every other man has a right to knock him down for it.” – Samuel Johnson I have a six-sided die. I’m going to roll it ten times, and record each roll. And when I’m done, I’m going to have an incredibly rare, bet-you-can’t-reproduce-it result!…
Answering ALL Your Questions
Posted by Ethan on December 14, 2012 
“And in the end The love you take Is equal to the love you make.” -Paul McCartney Every once in a while, I throw the chance out there (on facebook, twitter, or google+) to ask me whatever questions you want. Yesterday, for some insane reason, I invited people across all three platforms to ask me whatever…
Yes, we really, REALLY need Dark Matter!

“If you wish to make an apple pie from scratch, you must first invent the Universe.” -Carl Sagan The Universe is a lot like an extremely intricate cake. We view it today as a snapshot in time, now that it’s complete. We can view the whole thing from one point of view, determined by where…
