We’ve all seen that vast black hole. Its six billion solar masses are so dense no light can escape. It is so far away light from hot gas falling in takes 55 million years to reach us. Well actually, we’ve seen an image. Now that we’ve seen it, what do we know now we didn’t […]

Black hole mystery finds an original solution
“BLACK HOLE MYSTERY” says the cover of a recent Scientific American. “The first supermassive black holes formed earlier than seems possible.” The author is Yale astrophysicist Priyamvada Natarajan. “What are scientists missing?” the cover asks. Maybe the answer is: A grasp of quantum space and the topology of twist. It’s a massive problem in more […]
Ant-Man and the Sundance Kid
Ant-Man is back this week in a new sci-fi movie. Rumor says your favorite shrinking superhero’s set to shrink even smaller than before. This could set a trend. Will we soon see Ant-Man in action all the way down to Planck-scale? The sixties comics and the 2015 movie Ant-Man were about scale and a suit […]
The Sundance Story: The greatest (also the smallest) discovery of the science era
Strange all this Difference should be ’Twixt Tweedle-dum and Tweedle-dee! — John Byrom (1692 – 1763) Twist and shout … Come on and work it on out — Phil Medley & Bert Berns (1961) Australian physicist Sundance Bilson-Thompson made a stunning discovery. He starts with a simple entity—a tiny twist. With the quirky humor that […]
How does Planck-scale physics work?
Planck-scale physics is more than a hundred years old. Physics is starting to take it seriously. This is great because we can hope for exciting new science and technology to drive a new economy. Planck scale is the incredibly tiny scale at which physics actually happens. It is the scale at which space no longer […]
Plain talk about quantum theory: It has no place for space and that’s a problem.
Quantum physics is in trouble. It needs a new strategy. Physics is mostly based around quantum theory. When physics gets in trouble it affects everyone. Physics is the fountain from which our economy springs. Quantum theory seems so esoteric many think they cannot go there. Yet at heart the problem and the opportunity to fix […]
The universe has an arithmetic of its own that answers a deep question about the nature of math.
Here’s a burning question behind the facade of math: Is math a property of the universe that we discover (a view philosophy calls realism); or is math an invention of our minds (fictionalism)? If “our” math is a property of the universe then we may get it right or wrong but we can’t change it; […]
Stephen Hawking’s recipe for the universe may be good religion but it’s bad physics
Stephen Hawking says he has a deep belief. He calls it nothing. He says this is good physics. I say it it is not. He says it is real. I say it is only an idea. Explaining his own curiosity he says, ‘I wanted to understand how the universe began.’ Many physicists see this as […]
Out of this world: Are the laws of physics different in other parts of the universe?
Inflationary theories say the laws of physics should be different in other parts of the universe. Some have claimed to have observed evidence of variation. Now, in a high-precision study using a giant telescope (Arecibo; it’s the one James Bond and Natalya Simonova discover in GoldenEye), scientists observed no variation. But the universe may be […]
