What’s In a Metric? More Than You Might Think

For more than a hundred years a metric has been seen as a good thing. Turns out it’s not; indeed it’s definitely bad.  First, what’s a metric? That gets complicated; it’s an assumed property of space. It’s like a ruler science uses to make measurements of many kinds, like lengths of lines (both straight and […]

The Flow of Time

Does time flow? It is a fundamental question. It has confounded physics for hundreds of years. It still does. We sense the flow of time.  Today many physicists say this is an illusion. I say they don’t understand. Physics at the very largest and the very smallest scales leads to a simple way to make […]

What Made the Big Bang Big? What Made the Big Bang Bang? A radical rethinking of our understanding of the universe

Two weeks ago we took a look at a question from systems engineer Muralidharan Thiyagarajan. Referring to the observation that space everywhere is expanding, he asks: ‘What creates the space?’ My answer is: At the Planck level (named for German physicist Max Planck who first described it) where space is made of incredibly tiny quanta, […]

The Laws of Physics Are Not Sacrosanct

We like to think of laws of physics as fundamental, as properties of the universe. Actually, not. They are our inventions, tales we tell ourselves in terms of concepts we construct. They are good statistical approximations. But they don’t tell us what’s really going on. The real world is happening at Planck scale, named for […]

In Search of the Physics of Causation

Does the world work on cause and effect or is this a world of random chaos? This question needs exploration at the universe’s smallest scale, far smaller than that of the atom. We are coming to see the answer is: neither and both! Long ago, physicists as well as philosophers wrestled with this question. Albert […]

The Next Scientific Revolution

Breaking news: We are seeing a new Scientific Revolution. It will be the biggest ever. And I mean ever. Odds on it will be called “the Planck revolution”. Does German physicist Max Planck deserve this? I don’t think so. I think of it as the Riemann revolution. Readers know that more than 150 years ago […]
