Scientists May Have Just Figured Out Why Time Moves Forward, Not Backwards

January 29, 2016 | by Alfredo Carpineti   Griffith University Associate Professor Joan Vaccaro has put forward a suggestion on why there’s a difference between the future and the past. According to her calculations, the laws of physics don’t have to distinguish between time and space, but since we don’t experience time in the same way as space, something must make time different. And she thinks the answer is in a special class of quantum phenomena. Certain quantum phenomena don’t behave in the same way if you’re going forward or backward in time, and she suggested that these are the key to understanding the arrow of time – the “asymmetry”, or one-way direction, of time. And she said that in particular, subatomic particles known as K and B mesons could provide some interesting information. Her research is published in the Proceedings of The Royal Society A. “If you want to know where the universe came from and where it’s going, you need to know about time,” Vaccaro said in a statement. “Experiments on subatomic particles over the past 50 years show that nature doesn’t treat both directions of time equally. In particular, subatomic particles called K and B mesons behave slightly differently depending on the direction of time.”   Here’s an analogy: If you leave a cup of coffee on the table you’d expect it to stay there. Sure, maybe you can move it around on the table, but it would still be a...

What is the Higgs Boson, and why is it so important?

By Graham Templeton on June 24, 2015     The Higgs boson is, if nothing else, the most expensive particle of all time. It’s a bit of an unfair comparison; discovering the electron, for instance, required little more than a vacuum tube and some genuine genius, while finding the Higgs boson required the creation of experimental energies rarely seen before on planet Earth. The Large Hadron Collider hardly needs any introduction, being one of the most famous and successful scientific experiments of all time, but the identity of its primary target particle is still shrouded in mystery for much of the public. It’s been called the God Particle, but thanks to the efforts of literally thousands of scientists, we no longer have to take its existence on faith. Why has the Higgs been the subject of so much hype, funding, and (mis)information? For two reasons. One, it was the last hold-out particle remaining hidden during the quest to check the accuracy of the Standard Model of Physics. This meant its discovery would validate more than a generation of scientific publication. Two, the Higgs is the particle which gives other particles their mass, making it both centrally important and seemingly magical. We tend to think of mass as an intrinsic property of all things, yet physicists believe that without the Higgs boson, mass fundamentally doesn’t exist. The reason comes back to something called the Higgs...

Syria civil war: State-of-the-art technology gives President Assad’s army the edge

The regime has lost over 60,000 men since the war began, but new Russian equipment is helping turn the tide Robert Fisk, Isriyah, 27/02/2016     You can see the Syrian army’s spanking new Russian T-90 tanks lined up in their new desert livery scarcely 100 miles from Isis’s Syrian “capital” of Raqqa. There are new Russian-made trucks alongside them, and a lot of artillery and – surely Isis’s spies are supposed to see this – plenty of Syrian soldiers walking beside the perimeter wire beside Russian soldiers wearing floppy military hats against the sun, the kind they used in the old days in the summer heat of Afghanistan in the 1980s. There’s even a Russian general based at the Isriyah military base, making sure that Syrian tank crews receive the most efficient training on the T-90s. No, Russian ground troops are not going to fight Isis. That was never the intention. The Russian air force attacks Isis from the air; the Syrians, the Iranians, the Afghan Shia Muslims from north-eastern Afghanistan, the Iraqi Shias and several hundred Pakistani Shias must attack Isis and Jabhat al-Nusra on the ground. But the Russians have to be up in the desert to the east of the Aleppo-Hama-Homs-Damascus axis, both to train the Syrian tank crews and maintain an eastern base of forward air controllers to guide the Sukhoi bombers on to their night-time...

The Donald—–The Good And Bad Of It

by David Stockman • February 27, 2016   America will need the Almighty’s unstinting favor if Donald Trump becomes our 45th President. Still, blessed be The Donald for running a demolition derby in the Republican primaries. There is no hope for the future of capitalist prosperity and a free society at home and world peace abroad unless the Republican Party is destroyed, and by golly Trump may well accomplish the deed. We need to be clear. There is no longer a Republican Party rooted in the main street highways and byways of America. What’s left of it is not really even the xenophobic, nativist, crypto-racist flotsam and jetsam of the populist right that The Donald is successfully calling to political arms. The fact is, the GOP has mutated into the Warfare State party. Nestled comfortably in the Imperial City, it operates a plethora of special interest rackets which underwrite its incumbents’ bi-annual electoral campaigns out in the provinces. In the interim, GOP politicians idle their time in the capital and on foreign junkets conjuring and embellishing scary stories about terrorist threats and hostile regimes. So doing, they perceive enemies of the American Imperium to be stalking the planet everywhere and even creeping onto these exceptional shores. In a word, as the party of the Warfare State, the GOP’s main business has become promoting the agenda, campaigns, machinations and glory of the Imperial City. Whenever its pro forma rhetoric about small government and fiscal prudence becomes inconvenient to the needs of the military/industrial/surveillance complex or the fund-raising requirements of its special interest rackets, the GOP’s putative conservative economics platform quickly...

Week 20: The Russian-American Agreement on Syria?

THE SAKER February 24, 2016   The recent agreement between the USA and Russia really solves nothing, it does not even end the war, and both sides are expressing a great deal of caution about its future implementation. And yet, this is a huge victory for Russia. While it is too early to say that “the Russian won in Syria”, I think that it is now fair to say that the Russian position on Syria has won. Here is why: First: nobody is suggesting anymore that Assad will be ousted or Damascus taken. That, in turn, means that everybody has now recognized that Syrian Arab Republic, backed by Russia, has successfully repelled the aggression of the huge coalition the AngloZionists built to overthrow Assad. Second: Russia has forced the UNSC and the USA to admit that the vast majority of those who fight Assad today are terrorists. Of course, this is not how this was declared, but if you look at the organizations which the UNSC has already declared as ‘terrorists’ then you already have an absolute majority of the anti-Assad forces. This means that the moral and legal legitimacy of the anti-Assad forces lies in tatters. Third: regardless of what Erdogan does actually try to do next, there are now clear signs that neither NATO, nor the EU nor even the Turkish high military command want a war with Russia. And...
