Physics has long been confused about the concept of ‘now’. New insights show that it is fundamental.

A sense of Now is the universal human experience. Yet modern physics cannot handle the concept of the present moment. Indeed relativity—our great theory of space and time—insisted on embedding it within a time dimension and then crossbreeding this dimension with three space dimensions to make spacetime. This was a blunder. It blocks progress. Physics […]

A Cosmic Puzzle Provides Insights into New Physics

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 […]

The Point of the Universe

A new understanding of the universe is wending its way into our world. What is it? Where does it come from? First let’s look at the old understanding. The Big Bang is the standard model of cosmology. It is based on general relativity and on evidence that space itself is expanding. It projects this picture […]

Fields of Dreams

Here is a mystery that needs help from armchair philosophers. Nowadays physics describes the world in terms of “fields”. What, then, is a field? It is weasel math that physicists invented to allow them to ignore the paradox of action at a distance. In the annals of thought the concept of action at a distance […]

Iridium Skies Will Become Safer

Iridium Skies Will Be Safer Losing an international flight over the ocean should soon become a thing of the past. This is a perk that we will get from a new satellite array and a new airspace-safety business. The new satellites will do much more than that. Raymond Hall, a former trans-Pacific pilot, says they […]

Billion Dollar Bugs

How about a multi-billion-dollar good-news story? Science may have found a way to grow more food. It’s a source of nitrogen: bacteria that live in leaves. It may be worth a mint in new ecosystem services, which is a name for what Earth does for us by being there. Here’s the scene you need to […]
