There are billions of black holes in our universe. Maybe gazillions. Stephen Hawking says they give off a strange kind of radiation. So we should see them, right? Here’s a cosmological Catch-22. To set the scene, the Albert Einstein Institute says: ‘If, in our universe’s fiery youth, “mini black holes” of very little mass had […]

A New Reality Check for Relativity
This week we take a look at a new telescope. It is called CHIME. Its design is unconventional, using cylinder-shaped antennae rather than dishes. There are five of them. Each has a parabolic shape to focus the signal. Construction of the 10,000 sq. m. array is now underway. First operation is set for next year. CHIME […]
Black Hole Breakout
The latest science news features a big black hole that is way too big. Big black holes are hot these days. There are two reasons. Big black holes are so extreme they confront us with puzzles that test the limits of our theories. And new telescopes are showing us more crazy things that big black […]
Near Earths Other Earthlike Planets in the Milky Way
There’s a planet in the news. An international team of astronomers using NASA’s Kepler spacecraft has spotted the most Earth-like extrasolar planet ever found. Seeking Earth-like planets is what Kepler’s all about. Indeed thanks in large part to Kepler new planets are old hat these days. The first confirmed discovery was 27 years ago. Around […]
First Stars
Here’s more news from big telescopes. The galaxy depicted in the illustration is called CR7. It has a football flavor: Google tells me CR7 is Cristiano Ronaldo, star player for famed Spanish soccer team, Real Madrid. The galaxy named after him shows up way down on page three of my search results! That bright patch […]
Do Stars Make Buckyballs?
No doubt you never thought about this question. But suddenly it is hot science news. The answer that we get is: Yes. And it has interesting implications. The story starts with the odd properties of carbon. (It’s our story too because they are the basis for life, not to mention much of our industry.) Carbon […]
Black Hole Bonanza
Another stunning discovery hits the astronomic news: Seems there are big black holes in galaxies all over. This opens a new chapter in the quest to understand the role of black holes in our universe. But its significance may run even deeper: a step toward unraveling the mystery of dark matter. Last year I reviewed […]
A New Eye on Our World
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 […]
Lessons from Lost Worlds
In The Singular Universe and the Reality of Time Brazilian philosopher, Roberto Unger, and American physicist, Lee Smolin, team up to bring unruly mathematics and fanciful multiverses under control. They seek a renaissance of natural philosophy—ideas—as a driver of future physics. Let’s swing along with them. Central to their thesis is the idea of the […]
