How did cold dark matter get cold?	Dark matter cools - in fact, all temperatures cool over time - just because the Universe is expanding. Say I have a bunch of dark matter particles, all moving with some particular speed relative to each other. As the Universe expands, it pulls these particles apart in addition to the random motions they already had. ...	[ "Meta\"-cold dark matter, also known as m\"CDM, is a form of cold dark matter proposed to solve the cuspy halo problem.

how do chemical attacks work? ie. the one that recently happened in syria?	Conventional weapons typically involve explosives as their payload. They explode, the pressure wave and shrapnel cause damage, but then it's done. Chemical weapons replace the explosive payload with one that spreads a specific chemical gas into the air. Once the chemical comes in contact with a person, it reacts in so...	[ "The agreement by Syria to destroy its chemical weapons arose at a time when the United States and France headed a coalition of countries on the verge of carrying out air strikes on Syria in response to the 21 August 2013 Ghouta chemical-weapon attacks.

Why is it that all electrons are exactly identical?	Well, in quantum field theory, electrons (and all other particles) are quantized excitations of underlying fields which permeate the entire universe. There's an electron field, a down quark field, a photon field (the EM field), and so on. So, asking why two electrons are identical is like asking why two waves in the s...	[ "Electrons are identical particles because they cannot be distinguished from each other by their intrinsic physical properties. In quantum mechanics, this means that a pair of interacting electrons must be able to swap positions without an observable change to the state of the system. The wave function of fermions,...
how does side by side 3d video work without glasses?	Depth perception works by your brain taking two separate pictures, one from your left eye and one from your right, then smushing them together. 3D works the same time way, by having two different pictures that look like depth when smushed together a certsin way. Glasses help focus your eyes to the new convergence point...

why is it that the majority of reddit seems to be atheist, but /r/atheist gets so much hate.	It's because /r/atheist is not an atheist sub. It's an anti-theist sub. Most atheists are not anti-theists. Generally, anti-theists tend to be immature. This gets them a lot of hate.

How were "classic" novels critically received throughout history?	The question here is way too broad for a number of reasons. Are there specific writers--or even a period--you have in mind? By and large, I think it's safe to hazard that the the majority of classic works enjoyed some measure of popularity or recognition in their own time--hence their survival. The long moldering mast...

Do solar panels produce more energy the closer they are to the sun?	Distance affects the flux of solar radiation on the surface of your panel. As the solar radiation spreads in 3D, the further away you are, the less rays\m^2 you can intercept. So yes, distance is a big factor when comparing panels orbiting earth to panels orbiting mars (for example).	[ "Solar panels need to have a lot of surface area that can be pointed towards the Sun as the spacecraft moves. More exposed surface area means more electricity can be converted from light energy from the Sun. Since spacecraft have to be small, this limits the amount of power that can be produced.\n", "Solar panels...
does taking antihistamines mess up our chance to create a natural resistance to allergies?	The reason why you have allergies is because you have too much immune response. The antihistamines reduce swelling by acting on the blood vessels, not the immune system.	[ "Early exposure to potential allergens may be protective. Treatments for allergies include avoiding known allergens and the use of medications such as steroids and antihistamines. In severe reactions injectable adrenaline (epinephrine) is recommended.

why do 5 firetrucks show up whenever my condo has a false alarm?	It's because you live in a condo. One or 2 engines may be fine for a lone house but if a fire breaks out in a condo multiple people are at risk, as well as a very large amount of property.

Were the revolutions of 1848 a turning point in European social and political history?	Arguably, yes, though revolutions are never really as revolutionary as we like to imagine, and certainly I'd say the French revolution was the biggest turning point in this era.

why is it with all the advances in digital technology does "on-hold music" still have the broken, terrible, staticky, playback quality it did in the 1970's?	It's because of the audio fidelity of telephone networks, which is garbage. That has to do with a combination of backwards compatibility with a hundred year old system and lack of competition among telephone providers so there's no incentive to make it any better.	[ "The main advantage of any digital recording medium is that of consistent reproduction, which is why some of the first uses of digital recording were for instrumentation data and classical music.

To what extent did the hip hop artists of the 1990s influence the political and social atmosphere of the times?	Just as a reminder, because of the 20 year rule you're not going to get many responses that can fully cover the 90s influence, especially because the influence of 90s hip hop likely extends beyond just the 90s.	[ "Beginning in the 1960s, hip hop music was centered around the ideas of cultural discourse in urban communities where Latinos and African Americans resided.

Why is Greco-Roman polytheism considered a cult by today's standards? And on that subject, what signified the decline of it as a religious practice?	I don't think it is. What you're seeing is a confusion of terms. In the context of ancient religions, a cult is just a set of ritual religious practices (cf ''cultivation''). A text discussing "the cult of Isis" is talking about the collection of practices and observances that worshippers of Isis engaged in. Then in...

what causes water to foam up when boiling noodles?	The starch in the noodles will absorb more and more water until the starch molecules pop which transfers the starch to the water resulting in the foam. That's not super technically but I'm pretty sure that's the gist of it.	[ "Normally, boiling water does not boil over.

How conscious of their fate being a part of an experiment and their rights were the participants of Stanford Prison Experiment?	It wasn't to make them believe it was real so much as to make it feel more real.
