Superficially interesting article, but it didn't actually answer the question very well. As near as I can tell from this article, the answer is basically "because it was expanding". It then went into a discussion about the possible behaviors of the universe over time, i.e. expanding indefinitely, having its expansion rate become static, or collapsing. But this discussion is tangential to the question.

I also don't like how the discussion at the end was phrased. It started talking about fine tuning and making a mathematical argument as to the chances that our universe would have exactly the amount of mass it does (which I believe makes the assumption that the mass in our universe is random, though it was never stated). The problem with this is it's basically the argument that our universe must have been made by some external entity (i.e. "God"), without actually saying as much. I say this because there's no other good reason to try and make claims about the statistical likelihood of our universe having the initial conditions it did. And of course, it completely failed to mention that of course the universe's conditions are just right for it to have produced stars and planets and eventually life, because otherwise we couldn't be talking about it. There's a pithy name for this, but I forget what it's called. It also failed to mention the trivial solution to getting a universe that's fine-tuned just right, assuming random initial conditions, that doesn't require invoking any kind of supernatural being: infinite universes.

So you've got a bunch of responses, but as a guy with a Master's in applied physics I wanted to chime in with a bit more of a long explanation.

The word "radiation" just means that something radiates -- it travels off to infinity. In this case we're talking about electromagnetic radiation, which spans a vast continuum from radio waves through microwaves to infrared and red, across the visible spectrum to deep blue, then on into ultraviolet, X-ray, and gamma light. It turns out that this radiation is quantized -- meaning it comes in lumps of a certain energy E = hf where h is a fundamental constant and f is the frequency of the light (equivalently, f = c / L where L is the wavelength). Light also comes with a certain "kick" or momentum p = E / c. We knew the latter formula from classical electromagnetism but the former formula was awarded two Nobel prizes, one to Max Planck and one three years later to Albert Einstein.

It is presently thought that the blue side of the non-visible electromagnetic radiation spectrum (UV, X-rays, Gamma rays) is cancer-causing, while the visible and red-side of nonvisible is not. This comports with the Planck/Einstein law for the energy of the photons, which approaches the bond energies for several common atomic bonds in the visible spectrum and exceeds it as we go into the ultraviolet. (We essentially see light by having the light excite these bonds, but not so much that it tears them apart, so as they "relax" to their starting configuration they release the energy and activate neurons.)

Microwaves are about 1mm or 1cm long, on the red side. They are emitted by microwave ovens, cell phones, wifi hotspots, and millimeter-wave detectors. Right now it's not thought that these are "dangerous" radiation any more than white light is, because their "kicks" don't excite the atomic bonds but are instead absorbed by proteins as a whole, in a process we presently think is indistinguishable from any other sort of heat transfer. That is, they heat you up, but don't do much else.

If they did something else, probably very large changes would have to be made to our modern scientific understanding, which I of course would totally support if experiments bore it out. At present there are no good experiments which show any other effects of microwaves on biological tissue, other than the heating thing.

Announcing Julia 0.3.0 final
Somewhat pedantically, I discovered a bug where a daemon (which did this very similar code) started killing random processes. The issue turned out to be that it was test run as root once and the pid_file was owned by root, group root. So the write_pid() function failed (silently) and the cleanup script always took the pid that was in pid_file and sent it a kill 9, which was now stuck. Sometimes kill 9 would return invalid pid, sometimes it would kill some process. Fixed by removing the pid_file, letting the daemon create it, and checking that the write succeeded.
This is best thing I've seen all year.

IMHO, that was a very long-winded non-explanation. Basically the "answer" comes down to this:

1. We really don't know. We don't understand the rules of physics well enough to model the behaviour of stuff in such "extreme" situations.

2. If you still insist on asking that question, I could give you a plausible explanation of why the question is not really the right thing to ask: "small" black holes tend to evaporate very quickly through the process of Hawking radiation -- in effect producing photons, matter, and every possible kind of "stuff". So even if there was something akin to a black hole, early in the universe, (and if we could apply our rudimentary understanding of gravity and quantum mechanics to even talk about black holes and Hawking radiation) it wouldn't trap the stuff for long... in fact it would be spewing out stuff in copious amounts, and very quickly at that.

Freedom of movement is considered a constitutional right. http://en.wikipedia.org/wiki/Freedom_of_movement_under_Unite... If you live in a remote area where the only option is to fly commercial you may have a strong case.

However, my understand is these are only added to major airports to avoid encountering such a situation. As you don't need to fly to get from Chicago or NY to just about anywhere.

Which creates another issue. Your not re-screened after traveling from a minor to a major airport which renders these precautions practically useless vs an intelligent advisory.

>So presumably the density never actually got that high, or there is some other explanation we are not aware of.

density don't need to be high to get a black hole - the more the mass the less its minimal density has to be when black hole can be formed - the Schwarzschild radius of our Universe (which is mostly space with the specks of matter) is on the scale of 10B+ light years for example. So depending on how it is calculated and a lot of other stuff - we still can be inside expanding black hole :)

I just tried my own suggestion. For a random sampling of wavelengths from 390 to 700, I converted each to RGB using this function http://stackoverflow.com/a/3407960 Then I averaged the R, G, and B values. The result is 144, 122, 90 or #907A5A which is... a dim brown color, with a "hue" of 36 which is very orange.

Edit: undid sRGB conversion since I think i did it wrong.

Also even small (stellar) black holes are very massive — 5x sol and up — (since they tend to occur from the collapse of very large stars) so having one pass near or through the solar system could be catastrophic.

Primordial black holes are posited to be possibly so small as to be able to pass through the earth without interacting with more than a few atoms, which would make visiting them both difficult and not enormously interesting.

Edit: clarification and added info on primordial black holes which I looked up.

If I set off something that proves to be a fork bomb as an unprivileged user, kill -1 might be a reasonable approach. And note that kill exists as a builtin in bash, so you can run it without forking a process.

Hopefully doesn't happen often, but potentially very useful in narrow circumstances. The problem is it being -1, not it being available. If it took an argument to kill that you'd never accidentally generate as a PID then it might as well be a different function. Of course, with negative numbers otherwise referring to process groups, there's not a lot of room remaining, so yeah...
Can we judge it on how the police interpret these things now?

For example, the police are only supposed to shoot people when there's imminent risk of death or great bodily harm. Yet there is routine, if not common, overreach there, including one notorious recent incident that people are currently protesting with great vigor.

If you can't reliably enforce the rule that police aren't supposed to kill people except in dire emergencies, how will you do it for cell phone kill switches?

For one, it's obviously quite good literature, of the "manifesto" style favored by modernist movements.

Second, it makes perfect sense. It describes things seen in strolling around a city (Paris in this case), listing funny street names and shop titles. Plus some references to older art and poetry movements (namely dada and surealism), regarding their promise of a "fuller life" etc.

This is a serious issue. On the one hand, our current system makes a one-star review far, far more consequential than it ought to be. If EVERYONE leaves positive reviews, than a single negative is very powerful.

On the other hand, leaving positive reviews out of politeness does a disservice to others. I hosted a couchsurfer once (a woman) who told me about her experience with another host. This guy had 10-20 positive reviews. And he was a total creep. Hit on her the entire time, asked her to sleep with him, and was intimidating. She left as soon as she could.

But she didn't leave a negative review! And clearly, other women must have had her experience, yet they said nothing either. This guy was left free to continue his horrible behavior.

I don't know the solution.

Earlier this year, the ACLU won a case regarding the constitutionally of the no-fly list[1]. Basically, their argument was that you can't give up your Fifth Amendment rights (due process) when you travel internationally. Since this argument won, it implies that Fourth Amendment rights (probable cause searches) also cannot be forfeited.

Relevant quote:

"Accordingly, the Court concludes on this record that Plaintiffs have a constitutionally-protected liberty interest in traveling internationally by air, which is affected by being placed on the No Fly List." [2]

It's not like this question has a "right" answer, because we are describing different models as "perceptual" or "physical".

The same phenomenon happens in audio. The vast majority of musical synthesizers either model the perception of sound or the physical production of sound. For example, you can model a piano as a physical system with a vibrating string, or you can model it as a subjective phenomenon, constructing a frequency spectrum that sounds similar using FM synthesis, subtractive synthesis, additive synthesis, et cetera--none of which correspond in any meaningful way to the piano itself, we're really trying to trick the ear.

In the same way, I see RGB as a simplified physical model rather than a perceptual model, because it does correspond rather closely to physical reality, and it corresponds somewhat poorly to subjective reality. You can construct RGB as a simplification from a continuous spectrum model of radiation, all you have to pick the spectrum of your primaries. From there, you can use the RGB model in your physical simulations, such as ray tracing and photon mapping. Lab color does not work well for ray tracers because it does not correspond to physical reality: it is fairly nonlinear, and the coordinate system is awkward.

Likewise, RGB is a poor model for subjective perception (compared to Lab or XYZ) because its gamut is limited, and differences in RGB space do not correspond well to differences in subjective qualities. You can see how awkward RGB is for perceptual modeling whenever you use a color picker. It is frustrating to try and construct a pleasing palette of colors by dragging around RGB sliders, or even HSV/HSL sliders, because the model is so far from subjective perception that doing something conceptually straightforward, such as altering hue or matching luminosity, requires fiddling about.

In short, the description of RGB as a "physical model" is because we use it for physical simulations, as well as for working with hardware such as monitors and cameras. My description of Lab, CIECAM, XYZ, etc. as perceptial models are because we use those for modeling the subjective perception of color.

They have not. You'll have to point to a specific case because they have ruled for strip searches to be constitutional under essentially what amounts to probable cause.

Putting aside the question of whether or not MMW scans are actually legally equivalent to strip searches, the government forces you to show up to school. It does not force you to show up to the airport.

Depends on where you are. Springfield, MO for example has 5 Walmart Supercenters and 4 Walmart Neighborhood Markets. They also have at least one Hy-vee (They were planning on building at least one more, but I don't think it is completed yet). And that is just two companies with large stores. The town has several local and regional grocery store chains- and Dilons (Kroger). Many of these store do offer delivery service, too.

This all in a city that is less than 10 miles from one side to the other (160,000 population).

> Current US Code addresses air travel specifically. In 49 U.S.C. § 40103, "Sovereignty and use of airspace", the Code specifies that "A citizen of the United States has a public right of transit through the navigable airspace."

This doesn't sound like guaranteed use of commercial airports/airlines, it sounds like you'd have the right to fly yourself from your own airstrip, but not necessarily from an airport.

> Which creates another issue. As your not re-screened after traveling from a minor to a major airport which renders these precautions practically useless vs an intelligent advisory.

That is interesting.
Disclaimer: I'm speculating further than my knowledge of physics.

But if you add dark matter, could that push the Schwarzchild radius of the universe to 13B light years? That is, to the (observable) radius of the universe?

If so, then is it possible that the red shift of distant objects is a black hole effect (remember that in this scenario, we're inside the event horizon), rather than due to the expansion of the universe?

Would this also explain dark energy? It would require that red-shifts in a black hole be non-linear in distance, which I think is plausible, and that they be non-linear in the right direction, which I don't know enough to say anything whatsoever about.

> I guess what you mean by Bliss is what the Buddhists mean by Elightenment?

Although in Buddhism there is at some point the attainment of bliss (as a factor in the first jhana[0]) the goal is to let go of that bliss and go beyond. The next step in yoga is the realisation of atman, while in Buddhism the goal, Enlightenment (which is much better translated as "Awakening") it is the very opposite--the realisation of anatman (non-self). So they're not really compatible. In fact Buddhism is doctrinally sharply opposed to all strands of Vedic thought and practice.
