Planck-scale physics is not yet in its infancy. It is in gestation. Arranging a successful birth requires a strategic discipline. Walk before you try to run! For some reason (we will get to that) physicists seem doomed to run. Indeed—to milk the metaphor for maybe more than it is worth—they essay hundred-meter sprints before they […]
A quadrillion here, a quadrillion there, and pretty soon you’re talking about real money. – With a tip of the hat to U.S. Senator Everett McKinley Dirksen The economy has been sputtering for years; it sure could use a boost. How big a boost could it soon get from Planck-scale physics? A new answer to this question may surprise you. Science Seen […]
By 1900 the speed of light was known to be a constant. Many experiments had measured it. In 1905 Albert Einstein took a giant leap forward. He said this cosmic speed limit—denoted by the symbol c—is not just a measured fact; it is a fundamental property of the universe. This became the basis of his […]
The Large Hadron Collider or LHC was to find new particles. Aside from possibly the expected Higgs boson the report from the physics front is a deafening silence. This silence says a lot. At some $10 billion, the LHC is the world’s biggest and most costly science experiment ever. It pushes atom-smashing to new energy […]
Physics has a fundamental problem. In studying space and things in space, it needs to make measurements. To do this it needs some kind of ruler. It’s called a “metric”. There are many useful metrics. So before doing anything physics must choose the metric to use. The problem then is physics is not studying the […]
The world’s last great ice sheet is in the process of collapsing. This is not about climate change. It is about gravity and unstable foundations. The West Antarctic Ice Sheet (WAIS) will raise North America’s sea levels ten feet when it goes. It will shift some shorelines inland many miles. A new study sets out […]
It has long been a deep and frustrating puzzle. The charge on the electron, symbol e, is said to be an elementary quantum. That is, neither the electron nor its charge is ever seen to be subdivided. Lots of measurements reveal the charge on every electron has exactly the same value. For more than a […]
Why does our universe have three space dimensions? As if that question is not tough enough, string theory says that it has nine. So why do we see three? Some say there will never be an explanation, that it is just a “brute fact”. Others say this is one of the ultimate questions and that […]
As Chubby Checker sang and showed a 1960s generation, “Let’s do the twist.” Twist is not only an important thing. It is the only thing. Look around; all that you can see is made of twist. How so? The explanation starts with atoms and takes us through topology and Solitaire to the final fate of […]
