Closing in on Einstein's window to the universe

(Phys.org) —Nearly a century after the world’s greatest physicist, Albert Einstein, first predicted the existence of gravitational waves, a global network of gravitational wave observatories has moved a step closer to detecting the faint radiation that could lead to important new discoveries in our universe. …read more

Supernova ‘Way Too Bright’ To Analyze Sparks Astronomy Debate

By The Huffington Post News Editors

By John Matson

All supernovae are bright. When a star ends its life in a cataclysmic explosion, it emits a burst of energy and light that can outshine the rest of the galaxy in which it resides. But some supernovae are a little too bright—at least from the standpoint of the researchers trying to figure out what caused them.

A supernova discovered in August 2010 at the Pan-STARRS 1 telescope in Hawaii falls into that category. The supernova, PS1-10afx, is so far away that its light has taken nine billion years—more than half the age of the universe—to reach Earth. And at that distance, its apparent glow implies that the supernova shone with the luminosity of 100 billion suns at the source. But whether PS1-10afx is a superluminous cataclysm that defies explanation or a somewhat humdrum supernova that only appears extraordinary because of a chance cosmic alignment depends on whom you ask. In newly published studies, two teams of researchers have taken opposing positions on this question.

“It doesn’t match too well to any of the previous superluminous supernovae,” says Ryan Chornock, an astronomer at the Harvard–Smithsonian Center for Astrophysics. “In this case we find that it’s hard to explain this object with any of those models.” In a study in the April 20 issue of The Astrophysical Journal (ApJ), Chornock and his colleagues reported the supernova’s unusual attributes, including a redder-than-normal color, its rapid brightening and fading and its extreme luminosity. “There’s this class of superluminous supernovae that are a factor of 10 to 100 more luminous than a normal supernova,” Chornock says. “This is comparable to the most luminous examples of those.”

That combination of traits, however, seems to exclude PS1-10afx from any of the explanations that have been floated as an energy source for various extra-bright supernovae: for instance, a supernova exploding into a dense circumstellar medium, which would convert the kinetic energy of the blast into extra radiation or the rapid spin of a highly magnetized neutron star formed in a stellar collapse. Aside from its extreme peak luminosity, the researchers reported in their study, PS1-10afx is an oddball in almost every observable respect.

But what if the supernova was not actually as bright as it seemed? Gravitational lensing, a well-documented consequence of Albert Einstein’s theory of general relativity, can dramatically magnify and brighten the appearance of distant cosmic objects. (In other words, adopting the caveat on a rear-view mirror: “objects in telescope are dimmer than they appear.”) Such lensing occurs when two celestial bodies fall into alignment as seen from Earth: The gravitational pull of the intervening object bends the light rays from the background object, focusing them toward Earth like a magnifying lens. Studies of gravitational lensing have already been used to infer the presence of invisible dark matter in galaxy clusters and to discover otherwise hidden extrasolar planets orbiting distant stars. Now a group of researchers believes the effect may explain

"Let's Try This Cisco Thing Again," Says VirnetX

By Anders Bylund, The Motley Fool

Filed under:

A Texas jury found Cisco Systems not guilty of infringing on the patented security innovations of VirnetX last month. VirnetX shares have been falling ever since, and the stock price is less than half of what it was before that crucial Cisco verdict. Meanwhile, Cisco investors hardly noticed the event at all.

VHC data by YCharts.

The company isn’t appealing the Cisco decision to the next judicial level. Instead, VirnetX is asking for a whole new trial. The market response isn’t positive; VirnetX lost another 2% of its value this morning.

The action smacks of desperation. Here’s how CEO Kendall Larsen justifies this choice: “VirnetX fully believes in the jury system. We hope that with a new trial, a jury can decide the issues of infringement and damages based on the judge’s instructions and the merits of our claim.”

Well yes, a jury can indeed decide the issues based in case merits and the judge’s instructions. In fact, that’s what they just did. Larsen may not like the outcome, but he’s asking for a remedy that looks a lot like the alleged disease.

Didn’t Albert Einstein quip that insanity is “doing the same thing over and over again and expecting different results”? I think that witticism applies to VirnetX today. I see no reason why another jury would reach a different verdict in this case.

The wider powers of the appeals bench might change the outcome, but VirnetX isn’t going there.

The motion will in no way affect VirnetX’s ongoing damage-collecting process against Apple, which was found to trample on some of the same patents seen in the Cisco case. It also won’t derail the company’s “licensing efforts to the 4G LTE mobile markets.”

Not that those licensing efforts have been keeping Larsen up all night or anything. His company may be doing research and certainly spends a lot of time in courtrooms, but the business outcome of this activity is negligible. Actual revenues are measured in the thousands, supplemented by court-ordered payments. If the lucrative courts are turning against VirnetX, the business is sure to collapse in short order.

This $877 million market cap floats on a sea of red ink, clinging to dreams of a 4G-powered paycheck that may never come. Gamblers can play around with poker chips like VirnetX, but serious investors should stay far away. My bearish CAPScall on the stock has served me well so far.

Once a high-flying tech darling, Cisco is now on the radar of value-oriented dividend lovers. Get the low down on the routing juggernaut in The Motley Fool’s premium report. Click here now to get started.

Albert Einstein Was More Than A Genius – He Was Wise

By D. Cox

Einstein cartoon1 Albert Einstein Was More Than a Genius – He Was Wise

Condemnation without investigation is the height of ignorance.” – Albert Einstein

This cartoon, Einstein takes up the sword – published in 1933 by Brooklyn Eagle, shows Albert Einstein, who has shed his wings (labeled “Non- Resistant Pacifism”) standing next to a pillar labeled “World Peace.” He is rolling up his sleeves and holding a sword labeled “Preparedness.”

Einstein was an outspoken and world renewed pacifist. In 1919, when his Theory of Relativity propelled him to international fame, he used his success as a platform to promote his social agenda. Twice, he left his membership in the League of Nations because it would not stand on diplomacy alone. Einstein hated war; as a Swiss- German Jew, he had seen the results of World War I and detested it.

During the rise of the Nazi Party at the end of 1930, Einstein stood his pacifist ground. It was during this time that he visited the United States and made his famous ’2%’ speech.

In countries where conscription exists, the true pacifist must refuse military duty. In countries where compulsory military service does not exist, true pacifists must publicly declare that they will not take up arms in any circumstances…. The timid may say, ‘What’s the use? We’ll be sent to prison.’ To them I say: even if only two per cent announced their refusal to fight, governments would be powerless.

Einstein finally left Germany in 1933 after Hitler was announced as High Chancellor of the Nazi Party. It was then that he began to see the evil rising to the top of the Third Reich. Einstein renounced his German citizenship and officially became a United States Citizen. He stopped preaching pacifism and issued statements calling on the friends of civilization to unite against the oppression of Jews in Germany.

I loathe all armies and any kind of violence; yet I’m firmly convinced that at present these hateful weapons offer the only effective protection. Should Nazi militarism prevail, you can be sure that the last remnants of personal freedom in Europe will be destroyed.

You see, sometimes evil cannot be fought with words alone. Evil cannot be confined to logic. A beautiful Hollywood example quote would be when Batman’s Alfred said “Some men just want to see the world burn”. You see, evil does not come knocking dressed as the devil, or else who would let him in? Jesus Christ said it best: “Watch out for false prophets. They come to you in sheep’s clothing, but inwardly they are ferocious wolves” – Matthew 7:15.

Einstein discovered that after dedicating his life to rid the world of war, the countries he loved so dear needed weapons of war in order to fight back and defend themselves to create that peace that he so nobly fought for. We can find relevance in the wisdom of Einsteins’ words if you are listening. He scribed the sentiment below in a book he autographed in 1946:

Children do not listen to the wisdom of their elders. Nations do not listen to history. The bitter lessons of the past must ever be learned anew.

Albert Einstein is world renowned for his breakthroughs in science – but the title quote above, “Condemnation without investigation is the height of ignorance” so often attributed to scientific achievement and exploration was not directed to them. Albert Einstein was not speaking to scientists; he was speaking to pacifists – from experience.

Propaganda And The Face Of New America

By AK Fielding

propaganda cnn Propaganda and the Face of New America

“Propaganda, Propaganda, Propaganda.  All that Matters is Propaganda”-Adolf Hitler

Surrounded by four children, presumably representing all youth in America, Obama recently gave a riveting speech on gun control.  His announcement came in response to the Newtown shooting, or at least so he claims.  According to Obama, the youngsters on stage wanted speedy resolutions and had written heartfelt letters to him suggesting their fears and concerns about gun violence.  Interestingly, Obama neglected to mention what opinion any of them held about the United States Constitution, or the Second Amendment to be more precise.  Lest we miss the bigger picture, the article is not about the four youngsters or their misguided parents who should have never subjected their children to such outright propaganda.  Instead, the focus of this article is upon the shameless use of children, again, by Obama to promote his gun control agenda.

Indeed, there exists a gun control agenda; and unless Congress steps in, it will continue to rear its ugly head at every opportunity.  It is clear that Obama’s latest gimmick intends to set a precedent that will undoubtedly bring down the Second Amendment and ultimately our Constitution if left unchecked.  His shameless anti-American ideology knows no bounds.  Consider for example that following the tragic deaths of the innocent children in the Newtown shooting, Obama unashamedly lashed out against law-abiding Americans.  He has now followed it up by using these four children to move “forward” yet again in “hope” of bringing “change” to the way our society functions.  How else can he explain the basis of his 23 executive orders on gun controls?

Most of the suggested reforms from his 23 executive orders were illogical enough to confuse Albert Einstein and offer no real resolutions to avoid another tragedy like the one experienced by the Newtown community.  For example, what did Obama mean by offering more “resource officers” to schools?  Did he mean more teachers or more guidance counselors?  Precisely how would these “resource officers” help schoolchildren in the event another unfortunate episode occurs?  Nay, he was unspecific about these resource officers just as he is unspecific about any of his other plans.  He then emphasized the number of people who died “at the end of a gun”; but his statistics likely did not include those lives protected by guns.

Next, Obama claimed that someone with mental illness is “more likely to be the victim” in such tragedies but conveniently forgot to mention that the man guilty of the Newtown shooting was mentally disturbed.  Obama then demanded that Congress fund research to study how violent video games affect young minds.  Interestingly, he skipped adding violent Hollywood flicks or TV shows to his “research” list.  Why should he?  After all, doing so would mean lining up most of his supporters.

Of course, the most preposterous of all his reforms was the one that calls for universal background checks.  Yes, one can see all the criminals arriving in droves to fill up paperwork for background checks post haste.  It is obvious to those of us paying attention that Obama’s ridiculous call for action on gun control targets law-abiding Americans more and criminals less.  In his speech, Obama claimed outrageously that “we don’t benefit from ignorance.”  Yet, if we continue to allow him to encroach upon our liberties, are we not ignorant?  Is he not then benefiting from our ignorance?

Consider another tyrant who did the same thing in the early twentieth century.  Yes, this man too devised a grand scheme that included brainwashing the youth.  He controlled the nation by controlling the youth.  He effectively presented only one side of the argument-his side-and promised to reform the nation’s problems.  Most of us know the history of Hitler’s Nazi Germany and the outcome it produced.  Suffice it to say that Hitler’s tyranny left many men, women, and children dead, dying, or destitute.  Our children are not wearing brown shirts with swastikas and black shorts like the German children.  No one is forcing them to become storm troopers at the age of eighteen.  Nay, no one is brainwashing them with anti-American ideology either; or are they?
