“Other than the laws of physics, rules have never really worked out for me.” -Craig Ferguson When you think about the Standard Model of particle physics, you very likely think about all the matter, energy, particles, antiparticles, forces and interactions of the Universe. And you might legitimately worry that this is all there is. Never fear; it can’t…

“The conclusions, the bizarre conclusions, emerge as though with the greatest of ease: the reasoning is unbreakable. It looks as though he had reached the conclusions by pure thought, unaided, without listening to the opinions of others. To a surprisingly large extent, that is precisely what he had done.” -C.P. Snow, on Einstein’s 1905 work…

“All our sweetest hours fly the fastest.” -Virgil The speed of light in a vacuum is the limit for massless particles, but massive ones are limited even further! Have you ever wondered about that? We can get particles in accelerators up to 99.9999999988% the speed of light, and the Universe makes ones that are even faster!…

“If you put yourself in a position where you have to stretch outside your comfort zone, then you are forced to expand your consciousness.” -Les Brown On the one hand, you’ve got gravitation, the most powerful force in the Universe, trying to attract all the matter in it together. If it had its way, not only…

Ask Ethan #24: Cheating Time and Space

“For the wise man looks into space and he knows there is no limited dimensions.” -Lao Tzu You know the deal: it’s the end of the week, so it’s time for another Ask Ethan! You’ve continued to send in your questions-and-suggestions, much to my delight, and I’m pleased to tell you that this week’s question…

“The world owes you nothing. It was here first.” -Mark Twain When you think about where all of this came from — back to the beginning of the Universe — there’s a good chance it makes you a little uncomfortable. For this week’s Ask Ethan, our one remaining column here on ScienceBlogs, our reader vvv…

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 results of my observation are best explained by the assumption that a radiation of very great penetrating power enters our atmosphere from above.” -Victor Hess You might think of the largest and most powerful particle accelerators in the world — places like SLAC, Fermilab and the Large Hadron Collider — as the source of…

“Some say the world will end in fire, Some say in ice. From what I’ve tasted of desire I hold with those who favor fire. But if it had to perish twice, I think I know enough of hate To say that for destruction ice Is also great And would suffice.” -Robert Frost Depending on…

“Light thinks it travels faster than anything but it is wrong. No matter how fast light travels, it finds the darkness has always got there first, and is waiting for it.” -Terry Pratchett It’s the end of the week once again, and so let’s have a go at another Ask Ethan! Perhaps inspired by a great…
