The original paper makes it clear that this, like every other wormhole solution in General Relativity, requires "strange matter" - in their case, "as exotic matter, a massless ghost scalar field has been chosen". The interesting thing is that it links two stars together in a way that may have observable consequences (material would flow from one star to the other to keep the pressure in the cores equal, which would change how the star would evolve from one in isolation).
Note that these wormholes require the "exotic matter" to exist, so it's a mistake to say that this proves they can exist or whatever, as there is no actual evidence for any of the strange or exotic matter possibilities required to support them.
Now, suppose that such exotic matter does exist. Could this be used for transportation by an advanced civilization ? Maybe. You would have to find a wormhole end point in orbit about a black hole, and wait (or engineer) for the star to expand and for the black hole to "eat" the star's gas. If that process could go to completion, voila !, a naked wormhole would be left, and, if that were stable, you could use it for transportation.
Figuring out the necessary black hole engineering to do this is left as an exercise for the reader.
So what. If citizens are doing legal things, the police should leave them alone. Now, I understand that sometimes it won't go down like that, and the occasional disturbing the peace charge in such cases wouldn't bother me too much, but that's not a felony.
It looks like the undersea cable is fine and BGP is up, but there is no reachability past the landing site. This indicates that there is probably not physical damage, at least to the landing site and the first hop routers, but a cut somewhere after that. If I had to guess, I would guess that Gaddafi or his minions just told the ISPs to shut it down.
As the only Libyan landing site I know of is in Tripoli, this may also cut off the liberated areas in Cyrenaica.
Redundancy in routing is good - an overland link between Benghazi and Alexandria could be very useful right now.
I thought that the DOJ anti-trust division had all been frozen in carbonite. Now, it appears that they are awake and may actually do some good. When they are done with this, there is a certain search engine they might want to look at...
I actually don't think that there is that much connection.
I certainly know of MPEG participants who do not approve of MPEG-LA, and there are certainly also patents that the MPEG has to deal with, whether they want to or not.
I believe that the best ability to time macroscopic events (like laser pulses) is currently about 30 picoseconds, roughly 1 centimeter in vacuum, or 3 to 5 mm in fiber or coax.
I have tried to do picosecond level clock synchronization and it is very hard, as almost anything can introduce picosecond level delays. However, I wouldn't worry about that here as this is just FUD, as there is no way all traders are going to be located centimeters away from the trading "floor."
Librations are small variations in the rotation of the moon, either real ("physical librations") or apparent (the apparent ones - the "geometrical librations" - are caused by variations in the Moon's orbital motion, which is not uniform, and which changes slowly with time).
For a Lunar orbiter, the geometrical librations are irrelevant, and the physical librations are accounted for in the spacecraft ephemeris.
In all of this activity, do you think that they could, actually, do a movie of "Do Androids Dream of Electric Sheep" ?
It looks, by the way, from the trailer that Radio Free Albemuth is going to be pretty close to the original. Frankly, I am looking forward to that more than to BR prequels.
The Italian astronomer Schiaparelli concluded, based on observations in 1882/83, that Mercury was tidally locked (albeit with a large libration), and thus had an 88 day rotation period. This was in all of the textbooks, and many science fiction stories, for about 80 years. In 1965 radar observations of the planet showed that this conclusion was wrong. The leading versus trailing edge Doppler shift in the radar data showed immediately that the rotation period was 59 days, although Gordon Pettengill told me once that they didn't believe it at first, assuming the old optical period had to be correct and there had to be some sort of error with the radar data.
In the case of Mercury, the period of rotation of the planet, and its synodic period with Earth, means that every other observing opportunity shows the same side of Mercury to the Earth. Ground based Mercury observations are notoriously hard, and Schiaparelli must have seen the same features (his famous "figure 5") on multiple observations, and concluded that the planet was tidally locked, ignoring any discordant observations from the "in between" observations. I can't find a link, but Sky and Telescope for March has an article on Schiaparelli which goes into this in detail.
Probably not. These are not models of complicated things (like solar system formation). These are models to explain periodicities seen in light curves due to transiting planets., so it's just a matter of figuring out periods and amplitudes. A complicated case might be mis-interpreted, but there is no way that a simple case (i.e., one planet) will appear complicated (i.e., lots).
The new fiber is said to "allow for a more effective and liberal manipulation of light."
Upon hearing this news Speaker of the House John Boehner announced a bill to ban all Federal optical fiber research, saying it was further evidence of a "dangerous liberal bias in the research community."
There was (mid to late 1970's) also a version of Dungeons and Dragons written in PL/1 (!) that was on at least one of the MIT mainframes. I have often wondered who wrote that and what has happened to it.
I don't know about speed, but the weight difference is (was) considerable. The old machine was four full racks and (according to the Computer Museum) ~ 1200 pounds.

Why do you suppose private military companies [wikipedia.org] like Blackwater [wikipedia.org] exist in the first place?
I figured it was simple corruption and rewarding of the politically well connected.

Every time charges like this are filed, the District Attorney needs to face a recall effort. Every. Time. I will donate gladly to this effort.
It doesn't have to be successful for them to get the message.
I posted what I know here :

Uh, because official Arizona State University sites paid for by NASA are not prime goatse territory ?
I can remember when the US Air Traffic Controllers said that our ATC system was unsafe. Reagan fired them. (True, when they struck, but still...)

Crater rows are typically secondary craters (i.e., the stuff splashed out of some larger impact).
All the interesting stuff is on the far side of the moon. Wonder when they'll release those high-resolution photos...
Like this one ?
They are all available - I would suggest you start by browsing the gallery.
All of the Moon landing sites have high res images from LRO.
Heck, they even found the long missing Lunakhod 1, enabling it to be recovered by LLR.
In all of this activity, do you think that they could, actually, do a movie of "Do Androids Dream of Electric Sheep" ?

So, why didn't you celebrate on 2/29/2004 or 2/29/2008 ? If I was her, you'ld owe some back presents.

If you want to get sea-sick, drag your mouse to rotate the coordinate system. At an oblique angle, they bob around like drunken sailors.
You'd need a PhD to predict the tides.
No, just a computer.
I think that we will find that all solar systems are strange, including our own. It appears that planetary formation is a fairly chaotic process.

Oh, they will probably have atom level emulators of the hardware at that point.
