We All Live In A Croissant-Shaped Giant Bubble, Say Astronomers

by Jamie Carter, Forbes

Physicists have revealed a refined new model of the heliosphere—the vast region around the Sun extending more than twice as far as Pluto—that depicts it as a crescent-shaped magnetic force-field resembling a freshly baked croissant.

We Actually Live Inside a Huge Bubble in Space, Physicist Proposes

by Becky Ferreira, Vice

What if the Earth, the galaxy, and all the galaxies near us were enclosed in a weirdly empty bubble? This scenario could resolve some longstanding questions about the nature of the universe.

From our vantage point here on Earth, the universe can seem like a relatively calm and static place. But astronomical observations over the past century have revealed that this giant thing we live in, whatever it may be, is mysteriously expanding at an ever-accelerating pace.

Physicists see nuclear wobbling in one isotope of gold

by  Deanna Csomo McCool, University of Notre Dame, Phys.org

Nuclei can be round, like a soccer ball, or oblong, like a football. Others are slightly oblong but misshapen, like a potato. One of the only two ways to observe the third shape, rarely encountered, is when the nucleus wobbles like a lopsided top.

Researchers had previously seen these rare triaxial nuclei wobble on their shorter, transverse axes. But University of Notre Dame researchers and collaborators recently discovered that the nuclei also wobble on their intermediate axes. Their research, “Longitudinal Wobbling Motion in 187Au,” was published recently in the premier physics journal, Physical Review Letters.

If There’s a Wormhole Hiding in Our Galaxy, Could We Really Find It?

by Yasemin Saplakoglu, LiveScience

Wormholes, passageways that connect one universe or time to another, are still only theoretical — but that doesn’t mean physicists aren’t looking for them. In a new study, researchers describe how to find wormholes in the folds of our galaxy.

‘Planet Nine’ may actually be a black hole

by Sid Perkins, Science Magazine

For nearly 5 years, growing numbers of scientists have blamed the weird orbits of distant solar system objects on the gravitational effects of an as-yet-undiscovered “Planet Nine” that lies in the icy realm far beyond Neptune. But a pair of physicists is now floating an intriguing idea that could offer a new way to search for the object: What if that supposed planet is actually a small black hole?
