When it comes to dark matter, the mysterious substance that makes up the vast majority of the mass in the Universe, there’s a whole lot we don’t understand or know about it. You might think that there are so many unknowns that are so huge that — quite reasonably — perhaps it doesn’t exist at all,…

This 1925 Bugatti Brescia was found in a state of profound neglect in a garage, and was auctioned off for almost a million dollars. It’s a beautiful work of art. It doesn’t run, but still…that would be a fine vehicle for a Sunday drive, once it’s restored. But it’s the wrong model! Way, way back…

When you close your eyes and picture a galaxy, what pops into your mind? For most people, it’s a beautiful, spiral shape, where a bright central region fans out with arms that wind around and around, over and over, littered with brilliant, glittering stars.

Donald Rasmussen: Coal miners’ physician, humble man

Dr. Donald Rasmussen, 87, spent more than 50 years in Appalachia treating coal miners with lung disease. He was at the forefront of efforts during the 1960’s to challenge the establishment’s views that exposure to coal mine dust damaged miners’ lungs.

What is not new Ultimately sea levels will rise several feet, given the present levels of CO2 in the atmosphere. We already knew this by examining paleo data, and finding periods in the past with similar surface temperatures and/or similar atmospheric CO2 levels as today. I put a graphic from a paper by Gavin Foster…

“Our knowledge of stars and interstellar matter must be based primarily on the electromagnetic radiation which reaches us. Nature has thoughtfully provided us with a universe in which radiant energy of almost all wave lengths travels in straight lines over enormous distances with usually rather negligible absorption.” –Lyman Spitzer, Jr. There’s nothing quite like looking…

Many are the lies and epic is the misinformation spread by the antivaccine movement. For instance, they claim that vaccines cause autism, autoimmune diseases, sudden infant death syndrome (SIDS), cancer, and a wide variety of other conditions and diseases when there is no credible evidence that they do and lots of evidence that they don’t.…

“I felt my lungs inflate with the onrush of scenery — air, mountains, trees, people. I thought, ‘This is what it is to be happy.’” –Sylvia Plath The modern world can often make you feel like you’ll never find anything good “playing by its rules” in it. This feeling is evoked, tremendously, in the songs of Bonnie “Prince”…
