Ices stripped off a long-lost moon may have provided the raw materials for Saturn’s rings and inner satellites before the Titan-twin slammed into its mother planet, new research shows.

Could the power of gravity be harnessed as a means of nearly instantaneous communication between planets—and even galaxies?
Good metaphors are expansive; they compare something we don’t understand, to something we do. You see in a new light both the object of interest and the substrate you rest it on.
Can and should we try to drill deep into the earth, past the crust and into the mantle? We’ve tried in the past but haven’t gotten far. If the earth was an orange, we’d have barely zested it.
On the 9th of December, Astronomers Madhusudhan, Harrington and colleagues recently discovered a massive gas giant planet, orbiting a star which they have coined the first carbon-rich world ever observed. […]
We’ve reached the last Friday of Winter Break here at Denison, so starting Monday, the students are back. This semester I will be breaking out my volcanoes/human culture seminar class, […]
Scientists at Europe’s best particle-physics laboratory have been able to trap a very small amount of antihydrogen—the simplest type of anti-atom—for the first time.
Country Strong hasn’t been taken seriously by film critics. I’m not going to review what they’ve said or speculate on why they said it. I’m just going to explain why […]

If you were a sophisticated and up-to-the-minute science buff in 17th century Europe, you knew that there was only one properly scientific way to explain anything: “the direct contact-action of […]
Football – yes, we mean soccer – divides the British capital into a medieval-looking map of invisible territories, frontlines and enclaves.
This year marks the 35th anniversary of the publication of ‘Montaillou’, a book in the French literary tradition that treats laziness with the gravity and intelligence it deserves.
One frequent question I get is whether we can break the light barrier—because unless we can break the light barrier, the distant stars will always be unreachable.
Metropolis, Illinois, a tiny town with a grand name, is a distant echo of this area’s planned greatness
The theoretical physicist believes that gravity is an emergent phenomenon, not the elemental “force” that Newton and Einstein theorized it to be. He thinks it is the result of patterns […]

Yesterday, SpaceX became the very first commercial company in history to re-enter spacecraft from low-Earth orbit. Another first was on November 23rd when the Federal Aviation Administration (FAA) issued a […]
There are few things we take more for granted than the concept of gravity. Through history, physicists like Isaac Newton and Albert Einstein have developed theories about the Universe that […]
Released just yesterday, Physics of the Future is my most ambitious book to date. Based on interviews with over three hundred of the world’s top scientists, who are already inventing the […]
When you talk about Classical music, you often begin with the three Killer B’s: Bach, Beethoven, and Brahms. If you talk about American photography, you need to begin with the […]
“The universe was not created by God, scientist Stephen Hawking has said in his new book. Professor Hawking believes the laws of physics were behind the Big Bang instead.”
As the science conference at Google HQ wraps up, the New Scientist reflects on some big ideas—from jet packs to the nature of time and gravity—presented in humble surroundings.
America’s demographic centre of gravity has been moving steadily eastward for over 200 years
This isn’t really new activity, but a report on the ongoing activity at Soufriere Hills on Montserrat in the West Indies. Soufriere Hills is a composite volcano that has been […]
“Physicists struggling to reconcile gravity with quantum mechanics have hailed a theory—inspired by pencil lead—that could make it all very simple.” The New Scientist reports.
There are some signs that the new dome at Redoubt might be beginning to crumble in a piecemeal fashion, but nothing dramatic so far.
Wrapping up a crazy week with some news from North Korea, calming the Katla nerves, volcano insurance and the steady lava lake at Kilauea.
“It makes no difference whether determinism is true or false. We can’t be ultimately morally responsible either way.” A philosophy professor takes the gravity out of the free-will debate.
A recent study by members of the Harvard-Smithsonian Center for Astrophysics has been getting a lot of attention – one where it was suggested that we are very close to the […]
So let’s now speak about the future. You may have heard about the asteroid Apophis, which is about the size of the Rose Bowl Stadium. It’s said that the large […]
Commercial space tourism is no longer such a distant dream. Over the next decade or so, we are going to start seeing the development of quite a few interesting relationships […]
