Teleporting may be an everyday event throughout the universe. Physicists experimentally demonstrated it some time ago. Recently they set a new distance record: six kilometers. Sounds like progress. Problem is that nobody knows: How does it work? ‘Beam us up, Scotty’ are the magic words that Star Trek fans know make it happen. In Captain […]

What’s Wrong with Relativity?
There is no absolute frame of reference. It’s called the Principle of Relativity. Problem is: The principle is wrong. How so? Let’s take a closer look at what it is. Italian physicist Galileo Galilei had an idea. He said an experiment that’s done inside a smoothly moving ship can’t tell you that it’s moving. In […]
The Window into Planck-Scale Physics
He that breaks a thing to find out what it is has left the path of wisdom. – J.R.R. Tolkien How can we possibly develop Planck-scale physics? Since 1899 we’ve known that Planck scale is incredibly tiny. We need to go there; it’s where the real action is. New theories (such as string theory) tap […]
Physics Says There’s No Free Will Is Physics Right?
The concept of free will presents a problem. Physics is all about the rules of causation. Once there are rules there is no room for free will. This seems incontrovertible. But we will see that it is wrong. The argument for lack of free will persuades many physicists. Albert Einstein was a big fan of […]
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 […]
A Breakthrough is Underway New physics will drive new technologies
Breakthroughs in physics drive the economy. Our economy could use new drive. Canadian Blackberry innovator Mike Lazaridis understands this. ‘We need a new discovery,’ he said a few years ago and gave $170M to endow the Perimeter Institute to study fundamental physics. History offers examples. In 1687 Isaac Newton kicks off mechanics. It set the […]
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 […]
Making Space
Precise measurements say the universe is expanding. The measurements don’t show new matter. They show new space. This leaves those who think of space as empty with a conceptual puzzle. As cosmologist Marcus Chown once said, ‘How can nothing expand?’ Muralidharan Thiyagarajan, who is a systems engineer with Infosys in Chennai, has another way to […]
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 […]
