A new cosmic contradiction is begging for an explanation. We’ve known for years that space is expanding. Now new measurements of the rate at which it is expanding seem to differ from previous ones based on the standard cosmological model. New physics often comes from measurements that don’t fit theory. Here is my take on […]
Black holes are in the news again. Only a few weeks ago news of two surprisingly big black holes colliding in a distant galaxy arrived at Earth. Now astronomers have found a closer and far bigger pair of black holes. First the gravity waves. A fantastically sensitive instrument called LIGO measured them as they rolled […]
Albert Einstein is mostly known for physics theories. Or for E=mc2 (though he didn’t write it in that way). But his biggest contribution was the boldness, number, depth, diversity, originality and sometimes sheer courage of his ideas. Every one of these ideas was controversial at the time; now they underpin the world economy. What’s the […]
What is time? This is the central mystery of physics. One might think that physics would give a clear answer. Not so. Although most physics is about change, it has lost touch with time. Indeed physics now cloaks time in myths. Let’s see what we can find behind them. British physicist Edward Anderson says: ‘The […]
Good news for India and for science: welcome to a new sophisticated telescope called Astrosat. The India Space Research Organization (ISRO) designed and built it. Launched a month ago on India’s Polar Satellite Launch Vehicle from the Satish Dhawan Space Centre, it is now in its 400-mile high orbit over the equator. Astrosat has new […]
We can find fundamental physics while meditating in unlikely places. My wife’s father had a fishing camp on a small island in a lake. He died when she was young. His remains lie in a village cemetery by a sandy track amid boreal forest. It is a lovely place. We visit it from time to […]
Here is a story that can save you money. It might even save your life. If we could see all of the organisms that surround us, we would see microbes, billions of them, many kinds of viruses, bacteria, fungi and archaea. Most of them do nothing to us. Some could help us. Others, if they […]
A new study has revealed how infection with measles exposes children to many other causes of death. This is something caring parents need to know about. Measles (aka rubeola) shows up as a rash. It is very infectious. Because it mostly just goes away we tend to think of it as a nuisance that keeps […]
Think for a moment about the big picture of physics research. New physics comes from analyzing strange events. That’s why the biggest and most expensive experiments create strange events. Such events usually happen in small volumes for brief times. For example, the $10-billion-dollar 27-km-long Large Hadron Collider (LHC) mashes two protons into a subatomic-sized volume […]
