Court Rejects Woman’s Lawsuit Claiming Hadron Collider Could End The World

Doomsayers, including a few physicists, worry that experiments at CERN could unravel the fabric of our existence. But a German court says no, reports Phys.org:

A German woman who feared the Earth would be sucked into oblivion in a black hole failed Tuesday in her court bid to stop the work of the world’s most powerful atom smasher.

The higher administrative court in Muenster, Germany, rejected her claims, ruling there was no evidence the work of the European Organisation for Nuclear Research (CERN) posed a danger to public safety. The court noted that the CERN’s own safety reports ruled out any danger to life. “Objectively, there is no evidence to doubt the correctness of these safety reports nor was any conclusive evidence presented,” it ruled.

The woman had failed in a previous attempt to stop the work of CERN in Switzerland at the Federal Constitutional Court in Karlsruhe. Other opponents have also sought to stop the experiments, fearing either a black hole whose super gravity would swallow the Earth or a theoretical particle called a strangelet that would in turn liquidise the planet.

NASA Reveals Youngest Black Hole

NASA made a major announcement today, revealing what it terms “the youngest known black hole in our cosmic neighborhood.” Photo and official text of the announcement below:

In this image, Chandra’s X-rays are colored gold, while optical data from ESO’s Very Large Telescope are shown in red, green, and blue, and infrared data from Spitzer are red.

Astronomers using NASA’s Chandra X-ray Observatory have found evidence of the youngest black hole known to exist in our cosmic neighborhood. The 30-year-old black hole provides a unique opportunity to watch this type of object develop from infancy.

The black hole could help scientists better understand how massive stars explode, which ones leave behind black holes or neutron stars, and the number of black holes in our galaxy and others.

String Theory and Black Holes Show Possible Path to Practical Superconductors

The unit cell of high-temperature cuprate superconductor BSCCO-2212

Alasdair Wilkins writes on io9.com:

A leading candidate for room temperature superconductors is the copper compound cuprate, but no one knew how cuprates facilitated superconductivity … until some brave souls looked inside a black hole and broke out the string theory to explain how they work.

Superconductors that can transmit massive amounts of electricity with zero resistance at room temperature are pretty much the holy grail of applied physics (with good reason), but we’re still a long way away from actually building one.

Indeed, even figuring out the theoretical underpinnings of a room temperature superconductor has proven tremendously difficult, although a team of MIT physicists may have found an unlikely — and brilliant — way to learn more about how they would work. But first, a little backstory.

Currently, there are two types of superconductors. One group is the low temperature superconductors, which can only work at temperatures near absolute zero and thus require gigantically impractical amounts of coolants.

Supermassive Black Hole Is Hurled Out Of Galaxy

This is shock and awe. Report from BBC News:

A supermassive black hole may have been observed in the process of being hurled from its parent galaxy at high speed.

The finding comes from analysis of data collected by the US Chandra space X-ray observatory. However, there are alternative explanations for the observation.

The work, by an international team of astronomers, has been published in the journal Monthly Notices of the Royal Astronomical Society.

Normally, each galaxy contains a supermassive black hole at its centre. Given that these objects can have masses equivalent to one billion Suns, it takes a special set of conditions to cause this to happen.

High-speed exit

The authors believe this could be the result of the merger of two smaller black holes.

Every Black Hole Contains Another Universe?

Ker Than writes on National Geographic News:
Black Holes Hold Universes

Like part of a cosmic Russian doll, our universe may be nested inside a black hole that is itself part of a larger universe. In turn, all the black holes found so far in our universe — from the microscopic to the supermassive — may be doorways into alternate realities.

According to a mind-bending new theory, a black hole is actually a tunnel between universes — a type of wormhole. The matter the black hole attracts doesn’t collapse into a single point, as has been predicted, but rather gushes out a “white hole” at the other end of the black one, the theory goes.

In a recent paper published in the journal Physics Letters B, Indiana University physicist Nikodem Poplawski presents new mathematical models of the spiraling motion of matter falling into a black hole. His equations suggest such wormholes are viable alternatives to the “space-time singularities” that Albert Einstein predicted to be at the centers of black holes.

What Would You See As You Plummet Into a Black Hole? (Video)

Hazel Muir writes on New Scientist:
A new interactive program reveals the spectacular light show you'd see if you dared to wander close to a black hole. It demonstrates how the extreme gravity of a black hole could appear to shred background constellations of stars, spinning them around as though in a giant black washing machine. The program's creators say it could be an excellent tool to familiarise people with the weird ways that black holes warp light. "It's useful for people to play around with the parameters to study how, for instance, a black hole would distort the constellation Orion," says Thomas Müller of the University of Stuttgart in Germany.

Chinese Scientists Create Artificial Black Hole

Popular Science reports on scientists messing around with something that could cause the end of the world: pocket-sized laboratory-made black holes.

Unlike a regular black hole, which traps light using the gravitational pull of the dead star at its core, this simple metal disc uses the geometry of 60 concentric rings of metamaterials to lock up light…bending beams into the center of the disc, and trapping them in the etched maze-like grooves.
