Space and the Logos and Art and Poems

Posts I find valuable to the world. Science, logic, reason, and the arts. Some evangelist bashing as well.

December 27, 2004: The Day Earth Survived Its Greatest Space-Ray Attack —Ever
It came suddenly from the distant reaches of the Constellation Sagittarius, some 50,000 light years away. For a brief instant, a couple of tenths of a second, on December 27, 2004 an invisible burst of energy the equivalent of half a million years of sunlight shone on Earth. Many orbiting satellites electronics were zapped and the Earth’s upper atmosphere was amazingly ionized from a massive hit of gamma ray energy.
The source of the invisible attack was a rare magnetar SGR 1806-20 on the other side of the Milky Way. These soft gamma ray repeaters, SGRs, occur when twisted magnetic fields attempt to re-align themselves and crack the magetar’s crust releasing the awesome burst or pulse of energy with a death-zone of a few light years. Magnetars have magnetic fields 1000 times those of ordinary pulsars -so powerful as to be lethal at a distance of 1000 kilometers.

jtotheizzoe:

Here’s a linkdown smackdown to give you some background, explainers, looks inside the facilities, and what today’s announcements from CERN mean and what they don’t mean:

What the f**k is a Higgs Boson?

jtotheizzoe:

Theoretical physicist Matt Strassler is at CERN this week, and he has a huge list of background on the Higgs, why it’s important, and what he thinks is going to happen tomorrow.

Send reporters here for context and education.

breakingnews:

Just posted to the university’s website:

Shortly after noon today, a Virginia Tech police officer stopped a vehicle on campus during a routine traffic stop in the Coliseum parking lot near McComas Hall

During the traffic stop. the officer was shot and killed. There were witnesses to this…

Is the Higgs boson real?

A couple of blogs, including viXra and Peter Woit’s Not Even Wrong, have now posted rumours that the Atlas and CMS teams see Higgs-like signals around 125GeV, though they say the evidence is not robust enough to claim an official discovery.

Some Alien Planets Could Be Made of Diamonds, Study Finds
Some alien planets could be packing some major bling, according to a new study that predicts planets around other stars could be made largely of diamond.
But while such a place might sound beautiful, you wouldn’t want to visit, scientists say. A diamond planetwould very likely be devoid of life and incapable of supporting living beings like us.
“We think a diamond planet must be a very cold, dark place,” Ohio State University Earth scientist Wendy Panero, leader of the study, said in a statement.
These potential giant terrestrial planets, whose insides could be up to 50-percent diamond, are dubbed “carbon super-Earths” by scientists. [Gallery: The Strangest Alien Planets]

Black Dwarfs will also be, technically, diamonds in the sky.

Quantum theorem weirdness gets weirder: Apparently the wavefunction is a real physical object after all
Check the link for the full explanation of what’s going on here (my biologist’s brain starts melting a little when it comes to wavefunctions). But here’s a quote:

“I don’t like to sound hyperbolic, but I think the word ‘seismic’ is likely to apply to this paper,” says Antony Valentini, a theoretical physicist specializing in quantum foundations at Clemson University in South Carolina.

I don’t wanna sound obvious, but that’s pretty hyperbolic.

New tests at the European science facility CERN yet again confirm the results of their prior experiment which showed faster-than-light particles, reports the BBC and The Washington PostBack in September, CERN scientists clocked neutrinos — funky, ghostly particles that pass through every square inch of Earth billions of times a second — at 60 nanoseconds faster than the speed of light. Sixty nanoseconds was all that was needed to confound living physicists by calling into question of the linchpins of modern physics: the Einstein’s theory of relativity, which stipulates that nothing can travel faster than light.
