Space bloggers (like me) who are signed up with the ESO news feed got word of this overnight. But the story was under embargo. You do not break the story until the embargo lifts or the ESO and Nature magazine gets very angry at you.
But some loud-mouth in Croatia violated the embargo. We were patiently waiting for the embargo to lift, biting our collective tongues, when mouthy jumped the gun.
We got an email from the ESO about an hour ago that said:
"I just spoke to the Head of Press at Nature, Ruth Francis, and we have agreed to LIFT THE EMBARGO on the Alpha Cen story IMMEDIATELY due to an unfortunate leak. You may run your stories."
Moving a ship between point A and point B faster than light can do it is the same as time travel. That's all that is needed. And time travel destroys causality.
No, that is not how this "warp" drive works. The drive in the original article is a variation on the Alcubierre warp drive, which only warps a bubble around the ship. It does NOT effectively change the distance between the start and destination. You can read the original paper here:
No, nothing can go faster than the speed of light because it will violate causality. Which is more or less forbidden by the entirety of physics.
The only way to avoid this is by some magic-juju like Parallel Universes, Consistency Protection, Restricted Space-Time Areas, or Special Frames (with Special Frames forbidden by Relativity). All of which look like desperate hand-waving, if you examine them closely.
Yes, and the fact that the clip has "Serviceman Burnside" and "Serviceman Chung" might lead one to believe that the writer of the codex had studied Ken Burnside's Attack Vector: Tactical hard-science spacecraft combat boardgame and Winchell Chung's Atomic Rockets website.
The question remains: What keeps us from building them? The fact that they do not produce waste than can be weaponized? For a nuclear power like India, perhaps that was a factor.
From a commercial power standpoint, it would have made more sense back in the 1940's to have developed thorium power reactors. Unfortunately for commercial power, back then the priority was creating large stockpiles of plutonium for the US military's nuclear weapon needs. Commercial power was only a secondary concern. So plutonium producing uranium reactors were developed instead.
Now that the cold war is over, commercial power is stuck with mature but inconvenient nuclear technology that creates unwanted plutonium. By comparison, thorium reactor technology is very immature. Lots of research money will have to be spent to bring it to maturity.
The future of Qt in relation to Tizen is uncertain. It was not mentioned in any of today’s press releases. The Tizen website does make reference to a native development, but does not provide any further details. Instead HTML 5 is promoted as the development environment of choice and in an elastic piece of thinking is given as the reason for the need to evolve MeeGo.
However, Qt is a key component in many MeeGo related projects (e.g. part of the reference design for the GENIVI alliance for IVI devices) and, as noted above, Intel have indicated that there will be backwards compatibility with existing MeeGo netbook applications.
It seems likely that politics has a role to play here. Qt came into the MeeGo project from Nokia. Despite recent moves towards open governance, is still very much associated with Nokia. Intel were unhappy that Nokia switched to Windows Phone and the member of LiMo (including Samsung) may prefer to avoid mentioning or relying on what is perceived to be a competitor's asset.
In our opinion the likely scenario is that Qt will continue to play a major role in Tizen projects, but it will not be promoted as part of the core primary developer environment. Qt may be included as part of the default offering or it may be left to integrators to provide a version of Tizen with Qt. A possible example of how this might work in practise comes from Nomovok, who today released a press statement indicating that they would provide a version of Tizen integrated with Qt as part of their Steelrat system.
Yeah, right, like that's ever going to happen.
The great unwashed are irrationally terrified that cell phones and wifi are causing brain cancer. How do you think they are going to react to giant solar collectors directing huge beams of freaking microwaves at the Earth? "Diabolical scientists plot to turn the planet into a microwave oven, film at eleven"
Wait, no Gamma in space? What about the gamma ray bursts? Too far away?
You might say that. Gamma ray burst occur in other galaxies. Way to far away to be harmful.
Such a burst inside our galaxy would probably be strong enough to cause a mass-extinction event on the entire Earth, so any astronauts who were killed would have plenty of company.
What do you think is going to be powering these space vehicles?
Solar power arrays. The insane Luddite activists went absolutely ballistic about the Cassini space probe with its piddling 72 pounds of plutonium in a sub-critical RTGs. Do you seriously believe that the activists and the politicians they control are going to allow NASA to put an actual full-scale nuclear reactor on a booster rocket?
Well, not to put too fine a point on it, but NASA wants active shielding for the sorts of natural radiation astronauts encounter in space. Cosmic rays, solar flares, and the Van Allen radiation belts. All of which are charged particles.
As a general rule, one only encounters neutrons, gamma rays, and x-rays from artificial sources, such as nuclear weapons and nuclear power plants.
So unless NASA is contemplating starting a space war with alien invaders from another solar system, they will be well served by active shielding.
there is a percentage of users where that procedure does NOT fix the problem. In those cases, Microsoft advises the user to return the phone to the place of purchase to obtain a replacement phone.
Sounds like the correct use of the term "bricked" to me.
Not to mention the fact that one can use Nokia's Qt framework in Python using the PyQt bindings. So you can make a professional looking GUI in minutes.
Somebody was trying to arrange a contest for artist to make an illustration of a cute and cuddly Mi-go from Yuggoth to use as a mascot for Meego. Sort of like a Lovecraftian "Tux" the penguin.

When a place gets crowded enough to require ID’s, social collapse is not far away. It is time to go elsewhere. The best thing about space travel is that it made it possible to go elsewhere.

Soon we in the US will not have the option of mailing a check (er, cheque), since our postal service is near bankruptcy.

I'm still dubious, since superluminal neutrinos would violate causality.

All devices like this do not convert heat into electricity. They convert a heat gradient into electricity. The original heat is still there.
Golly gee wiz. It's Tom Swift and his Ultrasonic Cycloplane!
