Icy snowball comet theory takes another hit - the "impossible" dunes of Comet 67P

The comet 67P has provided an avalanche of astonishing discoveries that may puzzle scientists for years to come. And one problem that will simply not go away is the seemingly impossible dunes, or dune-like ripples at the comet's neck. At its first observation, the feature drew virtual gasps of disbelief from scientists and science media. More recent, close-up images of the "impossible" dunes have only deepened the mystery. How does the electric universe explaining this baffling feature?

Comment: The only thing more astonishing is how desperately mainstream science clings to its original conceptions about comet composition, despite all the evidence coming in from Rosetta and other comet probes. What is behind their apparent refusal to give any credence to the Electric Universe theory, even though it provides simple, elegant explanations for cometary observations?


The weight of a butterfly, it's critical

A day that shook the world. What was left of Hiroshima, Japan.
The design for the first atomic bomb was frighteningly simple: One lump of a special kind of uranium, the projectile, was fired at a very high speed into another lump of that same rare uranium, the target. When the two collided, they began a nuclear chain reaction, and it was only a tiny fraction of a second before the bomb exploded, forever splitting history between the time before the atomic bomb and the time after.
At 17 seconds past 8:15 a.m. on August 6, 1945, the Enola Gay released the bomb from a height of 31,600 feet above the target, a T-shaped bridge in the center of Hiroshima, Japan.

The morning was cloudless, as the weather plane sent to scout for the
Enola Gay had reported in the hour before. If the weather had been poor, the plane would have set its course to one of the two alternate targets. As the bomb fell, a schoolboy closed his eyes and began to count as his friends hid along the way to school.

"I think we had all concluded that it was a dud," Theodore Van Kirk, navigator of the
Enola Gay, would later recall of the 43 seconds before the plane's cabin filled with the blinding white light of the bomb's explosion 1,890 feet above the target.
Going critical

A chain reaction begins when a stray neutron thrown from the nucleus of an atom runs into another nucleus, causing that atom to split apart, dislodging a couple more neutrons to collide with two more atoms, which break into four pieces and so on. When atoms break apart, some of their mass (the "m" in the equation E=mc²) is converted to energy, an enormous "E" of fire and heat and light and wind.

Comment: Blindly leading fledgling scientists and innocent workers through a project without a clue to the hazards, usage and intent of the results...would be interesting to see how many of these folks would have stuck with the job knowing then that what they were working on would set the world down a path to possible nuclear obliteration. We certainly are not the better for it with ongoing Fukushima-type disasters and the massive accumulated radiation counts from decades of testing by many nations, changing our environment and its inhabitants into a slow-moving nightmare we can't reverse. What's a couple more butterflies?

A "full-on Formula 1 kind of race" on the surface of the Moon is to be held as soon as next year. Private rovers will fight to grab the Google Lunar XPRIZE of $30 million.

Two companies leading in the competition - the Pittsburgh-based Astrobotic and Japanese rover-developer HAKUTO - have agreed to simultaneously release their rovers. They expect both machines to land on the Moon's surface at the same time.

"Once all the rovers are released and everyone's turned on and initiated...we'll line the rovers up, and then the green flag will go up, and the race is on. It'll be like a full-on Formula One kind of race on the surface of the moon," John Thornton, head of Astrobotic, told Popular Mechanics.

Comment: Looks like the next step is to have Google Moon.

Hunters discover world's first 10,000 year old baby woolly rhino in Siberian permafrost

Remains of the baby woolly rhino.
A baby woolly rhinoceros, dubbed "Sasha," has been recently unearthed in Russian region of Yakutia, becoming a sensation for paleontologists.

The remains of the extinct creature - a particularly rare and historic find due to its age - were handed over to the Academy of Sciences in Yakutsk, the capital of the Sakha (Yakutia) Republic, on Wednesday. The baby woolly rhino was found last September by Aleksandr Banderov, a hunter and businessman, and his friend, on the right bank of a stream flowing into the Semyulyakh River.

"We were sailing past a ravine and noticed hair hanging on the top of it," Aleksandr told the local YSIA news agency. "At first we thought it was a reindeer's carcass, but after it thawed and fell down we saw a horn on its upper jaw and realized it must be a rhino. The part of the carcass that stuck out of the ice was eaten by wild animals, but the rest of it was inside the permafrost and preserved well."


U.S. plans to develop "psychic supercomputer" to predict attacks

As the US government begins looking for creative solutions to its cybersecurity woes, it's focusing on "psychic computers," machines capable of predicting attacks long before they happen. But an army of omniscient supercomputers may raise new concerns for privacy advocates.

Every morning, hundreds of meteorologists wake, fill their coffee mugs, and take one bold look at the sky. What will tomorrow bring? Rain, sun, snow? Hurricane? Polar vortex? These are the predictions that meteorologists make every day.

Now imagine using the same idea to foresee the next cyberattack.

The US government is hoping to develop a computer which would do just that. The intelligence community is opening a contest to software engineers to see who can develop the technology.

Known as the Cyber-attack Automated Unconventional Sensor Environment, or CAUSE, the project was conceived by the Intelligence Advanced Research Projects Activity (IARPA) as a four-year race to develop the software. Whoever does so first will receive an as-yet undetermined financial prize.

Comment: This technology is a slippery slope. It may be originally used for cyberattacks, but it could applied in so many other ways that should give us all pause. There should be serious concerns for all if government implements a real life Minority Report

Comet 2

Newly discovered comet whizzed by the sun, surprising astronomers

NASA has captured the unexpected trajectory of a comet in a 15-second space video as it whizzed around the sun within 2.2 million miles (3.54 million km) of its blazing hot surface.

Discovered by NASA's Solar and Heliospheric Observatory (SOHO), Comet 2,875 is interesting for two reasons. Firstly, it is not part of any known family of comets. Most comets seen by SOHO belong to the Kreutz family - a single comet that breaks into smaller comets the closer they moved towards the sun. Secondly, most comets that come close to the sun, called sungrazers, do not survive as they are evaporated by the intense heat. The action of comet 2,875 was caught on February 18 - 21.

Apple's newest patent: iPhones trackable even when turned off

Your next iPhone may be trackable even when it's turned off, if Apple's newest patent is anything to go by. The Cupertino tech giant has just patented a technology that would "periodically exit an unpowered state and transmit location data."

The patent documentation details a "wireless data processing device" that would include "a timer to periodically power up the wireless device or portion thereof in response to reaching a predetermined time" and "a location services module determining a current location of the wireless data processing device using one or more specified location determination techniques."

What this means in practice is that the device would "fake" being turned off if it receives the wrong security code a certain number of times, and would periodically transmit location data. While this should help track down stolen devices, the patent raises privacy concerns.


Two tales of time: Carlo Rovelli vs. Lee Smolin

New Direction in the Foundations of Physics 2014

Following the New Directions in the Foundations of Physics conference, two interesting consecutive talks made the case for opposite points of view and it is best to present them at the same time. On one hand, Carlo Rovelli made the case for the emergence of space and time and talked about the possibility of having fundamental physical theories without talking about space and time at all. On the other hand Lee Smolin made the point for the reality of time and the possibility of change for the physical laws. Because the problem of time is very hard and there is no universally accepted solution, this debate cannot be settled for now.

Let's start with Carlo Rovelli's position. From general quantum gravity considerations, it is not that strange to consider the possibility that space-time is not continuous. But how can you recover time? There are intuitive arguments and mathematical rigorous arguments available.

Comment: The only reason we discuss time at all is because we experience it. As philosophers like Alfred Whitehead and David Ray Griffin suggest, the experience of time is inextricably linked to consciousness, perhaps irreducibly so. Perhaps the nature of time has more to do with the nature of consciousness than many physicists presume, or account for in their models?


Corrupt science: Panic over peer-reviewed climate paper's evaluation of global warming models

"Chief, we got a guy here who claims climate models are no good. How do you want me to discredit him?"
You've heard it said that the science is settled. And it's true. It is settled - settled beyond the possibility of any dispute. A fundamental, inescapable, indubitable bedrock scientific principle is that lousy theories make lousy predictions.

Climate forecasts are lousy, therefore it is settled science that they must necessarily be based on lousy theories. And lousy theories should not be trusted.

Put it this way. Climate forecasts, of the type relied upon by the IPCC and over governmental entities, stink. They are no good. They have been promising ever increasing temperatures for decades, but the observations have been more or less steady. This must mean - it is inescapable - that something is very badly wrong with the theory behind the models. What?

Comment: When even notorious tabloids like Nature magazine participate in character assassination instead of discussing the science of a published work, it is clear that the official scientific establishment is not based upon scientific and ethical principles. In this instance the UN/IPCC (and intelligence-related organizations like Greenpeace) are desperate to cover up of the observed fact that their computer models on climate change are unreliable.


Skyfall: Does the Russian meteor explosion portend more disasters?

In mid-February 2013, a meteor fireball streaked across the sky and slammed into the central Russian city of Chelyabinsk. The shock-wave resulting from the overhead explosion equaled the energy released from about 20 nuclear bombs. It damaged nearly every building in the city and injured thousands of people. RT went to central Russia to talk with witnesses and scientists, and to find out whether the Russia should get ready for more such phenomena.

Comment: Etymology of 'disaster':
1590s, from M.Fr. désastre (1560s), from It. disastro "ill-starred," from dis-, here merely pejorative (see dis-) + astro "star, planet," from L. astrum, from Gk. astron (see star). The sense is astrological, of a calamity blamed on an unfavorable position of a planet.
...and before astronomy was 'adjusted' to become the science of the study of planets, it was concerned with the study of comets and when they would return...
