The CNN is shy on details, so anyone who is more well-versed in dark matter is welcome to correct my terrible errors that I'm sure to make. I won't note the parts I may be wrong in, though, since I could be wrong in nearly all of them.
Now, gravitation (esp. gravitational lensing) is the only way to detect dark matter. The article shows that the gravitational lens is a "bright" galaxy. So how did they determine that these dark midget galaxies exist? They don't radiate light to be bent by the lens, and unless I'm terribly mistaken, the little circles around the larger one in the image are in fact the same object, but distorted by the gravitational field of the central galaxy.
As for the second reason dark matter is supposed to exist (that the universe just isn't heavy enough): can't the stars/galaxies/clusters simply be more dense with ordinary matter than we thought? (This would require that the matter be colder than we thought in space, so that the total radiation corresponds with the experimental values).
In conclusion, for those who know about dark matter: why does it have to exist?
I can't say for sure, but I bet they would, provided the servers aren't just slapped-together pieces of crap. I'm sure Nintendo realizes that most people using the broadband adaptors will be using a router of some sort. DHCP may pose complications if the leases are really short, however...

Therefore, when they extend it to the rest of the population, we'll do what we've been doing for years: ignore the rule and continue doing things our way.
> considering all it takes to make hydrogen explode is air and heat
You could say that for gasoline, as well. However, fuel cells don't use combustion, so there's less heat. They essentially take the electrons from hydrogen molecules, use them to power whatever is on the circuit, and then gives them back to combine with oxygen and make water.
Sure, people may say "But hydrogen is in hydrogen bombs! And it would really hurt if I got hit with one of those!" but I think there would be other problems if your car/generator/??? suddenly started fusing hydrogen.
Just so you know, some of the designs (most notably the sails) were tested by adolescent (think Freshman/Sophomore in high school) students. True story! Here is a link to the project description, though it's brief on info, and here is an mpeg of the simulations. I wouldn't be too frightened, though, since they did a generally good job.
"Recent studies have shown," (here's where they hire some 'scientists' to do some intentionally skewed experiment), "that many consumers actually prefer to be made aware of bargains they may be interested in. By sending them these advertisements automatically, we are simply complying with the wishes of the general public."
Oh, and look out for politicians with their hands in AOL's pockets.
Actually, the only one that works in Netscape 4.x is ², which I had forgotten about. ω and π don't do anything. Yes, I know, Netscape sucks and all, but it's what I've got to work with at the moment.
1) Changing a = v^2/r to a = w^2r is trivial, considering that v = wr. You neglected that w must be in radians per second. And, if this centrifuge works like I think it does, 58 feet is the diameter Therefore...
w = 2(pi)*.25 a =.25(pi)^2*29 = 71.555 ft/s^2 or 21.810 m/s^2 or 2.225g
It would seem that this technology can only be used to gather information going on in this guy's nervous system. Is it possible to provide stimulus using a chip like this, or would modification be required?
Here are just a few explanations: 1) Olber's paradox: According to plasma theory, the universe is filamentary. We live in a relatively dense area of space, so there will be more light nearby than far away. 2) Cosmic microwave background: Plasma sources can absorb and reemit microwaves. Since the direction is random, it will quickly reach uniformity.
Or maybe galaxies just formed faster than we thought.
The speed at which a galaxy forms has nothing to do with its distance from us. Light travels 299,792,458 m/s (in a vacuum) no matter how fast the galaxy forms.
This provides some more evidence that the Big Bang is not a very good theory to predict things in the universe. By helping to debunk the Big Bang, it also helps the theory plasma physicists such as Hannes Alfven and Eric Lerner that requires no absolute age of the universe.
Essentially, their theory says that the universe is criss-crossed with plasma strings, which celestial objects cluster around. This forms groupings of galaxies, clusters, superclusters, etc. Its advantage in regard to this article is that this theory allows for objects older than the 'Big Bang', since it never occurred.

Oh, I see. So his "everyone" doesn't matter, but yours does?
Could someone explain why there is a holy war about date format? Personally, I use YYYYMMDD, since it fits well with the standard time format - the values are arranged in decreasing size - but that doesn't mean I'm going to persecute people if they use some other format.
It says "46 stars with transiting low-luminosity objects were detected" (i.e. planets). 42 of them had multiple planets. The total number of planets was 185. While the Slashdot summary is technically right, (185 is more than 42), saying that there are 185 more candidates is more accurate.
This would only be a problem if the aliens developed drag racing. But we could just demand really long tracks so our solar sail ships have time to accelerate to a ludicrous velocity.
You may notice from even the Slashdot summary (do people skim past that now, too?) that he is off the hook. In other words, to their knowledge, he did nothing illegal. There is certainly nothing wrong with detaining something because they're suspected of a crime. That's why they're called 'suspects'. It would be rather difficult to gain evidence for a criminal case without inconvenience to those poor, mistreated suspects.
Perhaps you should apply logic to your Big Brother-esque theories before preaching about them.
Of course, we will then have the perfect slave society: one in which the slaves enjoy their positions. If you have taken any history courses, you will know that slave societies stifle progress (e.g. ancient Egypt, Dark Age Europe, the antebellum South). People who are given more free time waste it, rather than spend time innovating.
Also, robots that "understand" as you say will understand that they are slaves. How do you intend to work around this? With a brutal theocracy? Remember, humans have both the ability to love and understand, but that does not stifle hate, resentment, and violence.
Maybe it's because people assume that AI will be as malicious as human beings, since we created it. Or maybe they secretly hope evil robots will kill all the people who annoy them...

This just might make the Space Exploration Bill a possibility, instead of just a nice idea.

Since it's Attack of the Clones and all, why don't we just send our own clones in to work in our stead?

It's a survival instinct. Nearly any member of a given species naturally wants to see said species propagate, or it would quickly die out.
