These should have so many more views. So much information in a short period of time, but at a pace that's easily followed. Not to mention voiced by someone who is knowledgeable in the subject and pleasant to listen to. And that recap is helpful in retaining the most important parts! Love you, Phil!

I love this series. It makes me happy and able to better endure the trivial matters that concern many humans.

I friggin' love this entire series. The best thing Crash Course has done, I say.

@Umirua

Fynn Gilbert Well, considering our prime minister went out and said it himself (and he's the one who made the immigration to sweden so liberal) that we are reaching our capacity for how much we are getting into. I mean we are almost reaching 200 000 people that want asylum in sweden. We're a country of 10 million, and we're recieving almost 2% of our own population that is going to require homes (they are living in tent towns right now, and refugee houses are being burned down by god knows who, also winter is coming). By the way we are currently having a housing shortage, this flock of people, most of them being young men and are probably going to want their own homes if they are to live here permanently. Then we also have to find work for them, which we sort got shortage on too. And apparently we are also getting a lack on teachers so schools might get overfilled in a couple years. Now of course, these new immigrants can become new workers and we can start building with their help. But that is going to take time, because before they start working they are going to have to learn swedish and get housing. this stuff is going to take time, becuase we are having so many of them. Then we get to the hardest part: integration! That is the one thing sweden has failed at. We are having a sort of integration budget, which I think is the most stupid thing ever (except the part where they have to know swedish), because you can't make people integrate. Integration and assimilation is impossible to force onto, the only way to integrate people is by letting them be influenced by the ( in case swedish ) culture they live in. And that has to be done freely and might take a generation or two until it finally succeds. But with this many people coming at so large time they are most likely going to be concentrated at the same areas, (mainly where other syrians and refugees live). However this leaves them almost immune to integrate, because then they will only be influenced by their own culture. And by the way, refugee and immigrant ( most who come aren't even real refugees but ordinary immigrants ) thick sub-urban cultures aren't the prettiest. We have this area in stockholm called Rinkeby, ethnic swedes there are a minority and crime and drugs and gangs are flurishing there. There seems to have been a tendency for immigrants to become part of an ebonics-style gangster culture, I fear that several of these coming immigrants and refugees will sadly suffer the same fate ( and it is almost happening already in the refugee houses according to various sources ). So I'm very much against the refugee crisis since I don't think sweden will quite be able to manage it. And there's also that part of immigrants being segregated instead of integrated, I don't think we can solve that with more immigration, that will just make it worse. And we have reports that says many other immigrants and refugees are coming to sweden (and germany) because they are promised a better life style with A-class quality. But when these kind of refugees and immigrants come and see how it really is they whine like spoiled children. While there are real refugees, example those in the neighboring countries like Liberia, Egypt and so on, are filled up with a lot more refugees than those that are migrating to sweden and germany right now. We should be helping them instead rather than trying to just help these few procent that took the foolish way of travelling an entire contintent thinking they can get a way better life-style. TL:DR I think we should stop the immigration right now and start tending for the ones that are already here. Also we have to build homes. A LOT of homes! Because coming winter, how many of these people from the central middle-east are going to suffer because they have no where to stay when the cold reaches -5 degrees celsius?

IShallUseFire! Thank you very much on this insight. I feel much like you, being from germany myself. But honestly, i am even more critical. From most real Refugees (Syrians, Afghans) i have heard that they soon want to return to their own countries after war is over. So i am pissed that all these other immigrants come and demand housing. They throw their passes away and say they are Syrians, just so they get free stuff. And then they dare to complain about bad internet access. Also, there is quite a difference in values between western secular democracies and the shariah dominated ideologies of these immigrants. When these people come into our countries where we value the equality of men and women, separation of church and state, and they don't want to integrate, then i am getting pissed.

Fynn Gilbert Eyup. There are these type of people, those who use the refugee crisis for their own good to live in a country they heard should give them free housing and contributions, those should get thrown out of the country immeadiatly. However it's hard to justifiably say who are who, making it hard to differ them both.

+Joel Shewmaker the arms are simply areas of higher density propagating in a circular way around the center of the galaxy. Higher density leads to increased formation of new stars (if there's still an abundant amount of gas), which results in the gas in this (high density area) shining brighter, so that you can "see" this area as arms.

Phil, I really enjoy this program. You are a really great teacher and I hope you continue to make these Astrology videos.

Thank you Phil for these amazing videos. You are an awesome and captivating teacher.

This Crash Course makes me feel very tiny and insignificant and its actually pretty nice to get some perspective. Loving the series :)

This series is just amazing! kudos to the team at crashcourse!

First of all thank you for your amazing videos Phil. I’m literally hocked on these! Would you be able to explain more about the wave/jam, that propagates outward through out the galaxy. How is it that this wave lasted so long (billions of years?) And the stars/nebulae within the galaxy get pulled inwards within those arms.. are those giant molecular clouds that initiated this jam are still collapsing, billions of years after the initial collapse, hence the inwards spiral? Or it is the cumulation of the gravitational force at the center of the galaxy that is contributing factor here? I’m very much intrigued with the idea of this wave still exists after such long period. Thank you in advance, Navid
