A new visualization method shows the twists in space-time, calledvortices,thrown off after two block holes merge. Theoretical physicist andblack holeguru Kip Thorne says he gets about one greatidea every 10 years. Herecently unveiled what he considers the latest of theseonce-in-a-decadedoozies: a new way tovisualize how black holes stretch and bend the [...]

The Strange Physics—and Singular Sights—Inside Black Holes
August 4th, 2011 — Physics
It is late December and snow is swirling as Andrew Hamilton coasts upto hisoffice at the University of Colorado’s Boulder campus, in the foothillsof theRockies. On a blustery day like today, most of his colleagues arrive inSUVs orat least in cars shod with all-season tires. Hamilton rides in on hisCannondalemountain bike…. [...]

Fractal Black Holes on Strings | Cosmic Variance
March 19th, 2011 — Physics
Here’s a fascinating new result about black holesin five dimensions —actually from last October, but I missed it when it cameout. I just noticed itthis week because of a write-up by Gary Horowitz inMatters of Gravity, thenewsletter of the gravity group of theAmerican Physical Society. (I obviouslymissed David Berenstein’s post as [...]

The Sight of Twisted Light Could Reveal a Spinning Black Hole | 80beats
February 14th, 2011 — Physics
No, you can’t see a black hole. What you might be able to see, though, istheway in which relativity predicts a spinning black hole will bend space,time,and light around it. Scientists say in anew study in Nature Physics that theyare closer than ever to being able tosee this effect in faraway black [...]
Study: Hyperactive Black Holes Aren’t Caused by Galactic Smash-ups | 80beats
January 7th, 2011 — Physics
At the heart of most galaxies lies a supermassive black hole.And in somegalaxies, the black hole is bigger and badder than usual. Theseragingoverachievers, called active galactic nuclei, can be some of thebrightestobjects in space, sweeping up a huge amount of material from theirlocal areasand emitting enough energy to outshine the galaxies [...]
LHC’s Lack of Black Holes Rules Out Some Versions of String Theory | 80beats
December 19th, 2010 — Physics
You know those black holes the Large Hadron Collider was going to makeandkill us all? Well, not only are we still here, but the LHC doesn’t seemto bemaking black holes at all—their decay signature is markedly absent fromthe datacollected so far…. Read More »
