luckystriker Cool, maybe? But it is wrong, have you ever heard of TGF , terrestrials gamma rays flashes, they are generated by lightning on earth. A terrestrial gamma-ray flash is a burst of gamma rays produced in Earth's atmosphere. TGFs have been recorded to last 0.2 to 3.5 milliseconds, and have energies of up to 20 million electronvolts. It is speculated that TGFs are caused by intense electric fields produced above or inside thunderstorms! So you see , you don’t need a supermassive black hole or high Gravitational field! All you need is plasma in a high electrical field potential. so let’s not be too naïve!
+Heinskitz Hopefully, we'll see Phil again sometime in the not too distant future when CrashCourse comes up with a new series revolving around another branch of Science or probably something else altogether.
+Qazmax Kind of. The radiation... so much energy... it would effectively cook your cells to death, and would be powerful enough to pass through a good chunk of the planet, so more than half the world would be affected. Depending on the strength and size of the beam, it may affect the whole world. The Death Star, on the other hand, produced a super-laser that would destroy a planet... more destructive, less energy efficient, less likely to backfire and cook the staff.
+Roberta Tallienne Actually, if you take into account the range of the Death Star, it seems quite likely, that it was far less powerful... I mean, assuming that our Sun went GRB on us (Can't happen and would likely miss us, but that's not the point), chances are, our planet would turn into plasma in a heartbeat...
Good point, Ozix, however, the Death Star's superlaser can't be gamma rays, because then the radiation would kill all the technicians near the beam, or at the very least give them cancer.
So, black holes are the love child of 2 neutron stars making sweet sweet love in space that results in a gamma ray flash. 10:51 = my new txt notification msg.
+Kabuki Jo More like angry sex... and no, merging of two neutron stars is one and quite rare way for black holes to forms. Most of them form from the gravitational collapse (commonly and erroneously referred as death) of massive (about over 3 solar masses) stars. And to be honest I have not checked the literature since university on updates on how the ones in galactic barycentres form.
This show needs another season. Plz!!! Another season of CrashCourseAstronomy would be the best. So necessary and informative. There's a lot of other topics in this field. Do it! Plz!
+Jack Star Me too, it's less hyped and it's hard to get any decent scientific work on it since dark energy and the cosmological constant became pop stars in the mind of university geeks. Nevertheless, I am really interested in getting some idea if there are answers to look for further at the time, like what is its density distribution in galaxies in relation to the distance from the barycentre and whether the little research on the subject has tried to model it as a property of space-time, instead of following the hype and try to come up with some fancy math to explain results and make no falsifiable prediction, like string theory... which is like what degrees are handed out to student who create programming languages that are completely useless, but fun to talk about their features (aka bugs) when we are drunk.
GRB's and gravitational waves are the two most mind boggling subjects and my favorite subject to research (I very loosely use this term) on TH-cam. My mind barely let's me comprehend. Thank you for this video.
Last episode: The distance to the farthest galaxies is mindbogglingly ginormous. This episode: Here are bursts of light so powerful we detected them in the 60s on accident across that distance.
The universe is so huge you just know that somewhere, in some distant galaxies maybe, there have been planets with intelligent life that have been wiped out by one of these GRBs :/
It's so amazing that gravitational waves are used to explain why two neutron stars won't orbit each other forever and they just observed this phenomena for the first time a few days ago.
Just wanted to say thank you for creating such great content. the crash course channel is in my top 10 youtube channels, and as a lover of the skies and believer in human expansion into space, I am greatly enjoying the astronomy series.
me: "hey look miniladd posted a fallout 4 video!" *then looks to the next video down* "A NEW CRASH COURSE ASTRONOMY?!?!?! ALTKJNSDTL;KJM;LYKJM.LKTMYA;SdkJTA;KLJYLKMAYLKM"
I'm very trigger-happy with dislikes, but I can't begin to comprehend, what kind of person would dislike this. Also, I don't know if I said this already in some other video, but Astronomy is better than all the other Crash Course channels combined. I have never seen astronomy or even science taught in such enthusiastic and narrative manner!
Vow! This is definitely Phil's the most "High Energy" burst presentation of all. Enjoyed it immensely. Funniest statement "The Swift satellite sends coordinates down to earth so that more telescopes on the earth can join in on the fun" ... this was funny! Keep making more videos, Phil!
My grandpa worked as an electrical engineer on the Vela program and I interviewed him for a school project once. Thanks Crash Course Astronomy for sharing the impact that the Vela program and my grandpa had on science. All I knew before was that they never detected any nuclear bombs.
+Jose Rosas Well, mirar is the infinitive to look. Ve I think is I am looking, or I look. I'm not sure about that one... actually, isn't that veo? Yeah... maybe it's he/she/it looks? Or the past tense I looked? I don't know....
+Roberta Tallienne Ve is the imperative form of the verb but it's not used too much beacause you can confuse it with the verb go in it's imperative form.
Vela can be candle, sail, or a form of the verb to watch (example in context: "A: Pedro, viste la película?", "P: Todavía no", "A: Vela, es muy buena")
Every time I watch one of the your videos I say that is my favorite one but this time you have out done your selves . Incredible.I will have to watch this video numerous times just to be able to absorb all of the facinating facts.Thank you for putting this video together.I learn so much information every time I watch and it really is facinating.Greetings from Atlantic City New Jersey USA
MOAR. seriously, I love this show. So, few questions: do gamma ray bursts push these neutron stars through space? Do gamma ray bursts propel their respective galaxies through space from these huge energy emissions?
Thank you very much for making this video! Wow, Phil, you make everything sound amazing, cool and awesome because you are so passionate about space! Yeah, I guess GRBs are really fascinating. Personally, I am more interested in the processes that form them than the rays itself. I did not actually know they are from supernovæ and neutron stars collisions and I certainly never had heard the word ‘hypernovæ’ before. Cool. I though GRBs was background radiation from when the Universe formed. If not, what really is background radiation? Microwaves? Anyway, thank you very much for making this video! The next episode will be far more darker...
OMG How do you guys do to make every episode better, more interesting, and more mind blowing than the one before ? I regularly have goosebumps watching this show, and I love that. :)
I like his passion and energy and how he explains everything. I feel as though I gained so more knowledge than I ever have in school, in just a matter of minutes. Also he makes it more interesting perhaps it could be the fact that I often wonder about the universe so i'm more fascinated in it all.
iff the GRB's position was detected to be 7 billion lightyear that means tht GRB Happened even before the earth was born? isn't it ? or i m interpreting wrongly
It's worth mentioning that whenever we see a GRB that's a few billion light years away, the event happened a few billion years in the past; GRBs were much more common in that era, as I understand it.
Is it weird I feel that astronomy is the most spiritual of all fields of study? I mean I know I'll get a lot of hate if I admitted I'm someone who believes in both God and science, but I do and I feel like the more we understand space the closer we are to God. which is funny because I think people would expect the opposite.
+WonderfulAkari What does "God" mean though? Whatever attributes you put on your definition, they are just something made up by humans (or you). There are numerous attributes you could give to "God", so being a person of science, you have to weigh them all equally. Anything you dream up might be the true "God" since you have no evidence to support any of it. At that point it kind of becomes meaningless... it goes back to the classic argument, if God is all-knowing and all-powerful and all-good, why is there evil in the universe? Basically, you're just making things up in your mind to make yourself feel good.
+WonderfulAkari Well, You are made of the universe, and the universe made you. So, in studying the universe, you essentially are learning more about yourself. If you consider yourself to be the universe or the universe to be you, it doesn't really matter either way, because the answer is both.
+Luis Camilo It would also be the 3rd person singular conjugation of the "-ar" verb "velar" meaning to stay up or figuratively "to watch over", "to keep vigil over&" or "to safeguard". Which makes more sense/
Don't you get the chills when you say these terrifying facts? I would even imagine you standing in awe as a space interesting object/beam is aiming at you :O
I can't get enough of this show. This shit is making me want to change my major to a science major. My curiosity for the universe never ends. It's terrifying, exciting, and the best part is that it's humbling and grounding. After these videos I feel grateful to be able to live life and experience pleasure, pain, happiness, sadness...all of it. Earth is amazing, and we were all lucky enough to exist in this little window of time of life on Earth. It won't be forever. Someday there will be nobody left to understand the spectacular nature of the universe... and that used to bother me, but I actually think that's kind of beautiful now.
We can't see gamma rays though can we? from nasa: (remember: gamma-rays are not in the visible range of the electromagnetic spectrum so we consequently are not aware of the phenomena)
Funny thing, the first episode of PBS nova I ever saw was about gamma ray bursts, I tuned in right when they were talking about how they detected them with satellites during the cold war looking for nuclear weapons, and they saw the radiation from space..... and for a long time after that, I thought "PBS Nova" was a tv show literally about novas. But it was just a coincidence, that THAT episode happened to be about supernovas.
You should make that "DEEP SPACE .. TA TA DAAAA" joke a running gag! I watched it three times in this video, hilarious! It's a great show. Thanks Phil!
"Gamma Ray Bursts are the birth cries of black holes being born." Just about the coolest statement I've heard this year.
luckystriker me too 🤘

Love this guy, he is so passionate
+Isaac Chay And much better here than that ridiculous universe series which has humiliated so many scientists with their horrible editing choices.
+Isaac Chay totally agree!! I wished we could be as good!
+Isaac Chay It pains me to think that the series is coming to an end. Phil's definitely passionate and a great communicator!
you want him to make passionate love to you?
+Heinskitz Hopefully, we'll see Phil again sometime in the not too distant future when CrashCourse comes up with a new series revolving around another branch of Science or probably something else altogether.
Nothing like getting 360 no-scoped from halfway across the universe.
comment of the century haha
Universe: Meet me on rust
Us: rage quit
lol
Nice one !
😅😅 2 years later still most savage comment
Without a doubt, this is my favorite Crash Course series. I friggin' love it.
I’d love to see Phil get his own “Cosmos”-type tv show! I think his enthusiasm could turn a lot of people on to astronomy.
How did I miss this for 4 years? I’ve loved every episode.
If we see a GRB that is 6 billion light years away, does that mean it happened 6 billion years ago and we are just seeing the light now?
yes sir!
yes exactly sir we we see the past but we don't see the present because it is too far away,taking up to thousands-light-years away
Yep.
@Zain Mazloum that's if traveling the speed of light
Yes
Thinking of GRBs as the cries of a newborn black hole just gives me chills. 0_o
+Twosocks42 One of those really high-pitched banshee screams that we use to instill horror. Scary stuff, but you can't look away...
+Twosocks42 Yup, considering there could be hundreds of black holes born every second...
+Gabriel Turturea Well, if there's really 100 Billion Galaxies, that's still a small number.
+Gabriel Turturea *every day, not every second
The sound he used while saying that was the scary thing
That Wyoming joke was awesome xD
You forgot the word 'NOT'.
@@deborahhanna6640 "That not wyoming joke was awesome"?
I look forward to these every week.
Me too!
+Sexual Potatoes Me too, they've become a friday coffee break tradition :)
+Sexual Potatoes Well who doesn't ;)
+Sexual Potatoes This is the best science feature on TH-cam. When this run ends, I will start over with number 1 :-)
+Wild River Tom I hope it never ends.
This is the best Crash Course episode I’ve ever seen. Perfect combo of subject, writing, acting, effects, and editing.
so the GRB is the real Death Star?
+Qazmax pfft the Death Star cant even compare.
+Qazmax Kind of. The radiation... so much energy... it would effectively cook your cells to death, and would be powerful enough to pass through a good chunk of the planet, so more than half the world would be affected. Depending on the strength and size of the beam, it may affect the whole world.

Sex that would result in the biggest blast in the universe...damn, hope it was worth it...
+Kabuki Jo The fact that their climax entails the release of gamma rays makes that some rather powerful coupling indeed.
Talk about an explosive climax!
So the GRB is the money shot??
This show needs another season. Plz!!! Another season of CrashCourseAstronomy would be the best. So necessary and informative. There's a lot of other topics in this field. Do it! Plz!
witnessing the birth of a black hole... that's powerful
I can't wait till next episode! I love the topic of Dark Matter!
Love the series!
+Jack Star Me too, it's less hyped and it's hard to get any decent scientific work on it since dark energy and the cosmological constant became pop stars in the mind of university geeks.

Seems like someone had a little sad and scared bursts there c:
GRB's and gravitational waves are the two most mind boggling subjects and my favorite subject to research (I very loosely use this term) on TH-cam. My mind barely let's me comprehend.
Thank you for this video.
These episodes keep getting more and more scary.
Eh, it's space. I mean we were all gonna die eventually it's better to be fascinated on exactly how and when you'll be forgotten
Phil, you are an amazing storyteller, even if the subject is a specific photonic wavelength. SPACE IS AWESOME!
Last episode: The distance to the farthest galaxies is mindbogglingly ginormous.
This episode: Here are bursts of light so powerful we detected them in the 60s on accident across that distance.
The universe is so huge you just know that somewhere, in some distant galaxies maybe, there have been planets with intelligent life that have been wiped out by one of these GRBs :/
"Wyoming?" This made me laugh so much. 😊
Also that noise at 8:23 😋😆
EbyKat When did he say that?
10:52 Euuuueuueeuuueheheh!!! -Phil Plait 2015
somehow, I always forget that these come out om tuesdays, and I'm always pleasantly surprised when I get notified of a new episode.
I love it!
+dahulius
It's Thursday.
+Roberta Tallienne I hate tuesdays and thursdays...english not being my first language, I always confuse them....
Same me, only I constantly check my feed...😅
It's so amazing that gravitational waves are used to explain why two neutron stars won't orbit each other forever and they just observed this phenomena for the first time a few days ago.
I just love this series so much.
These episodes are always the highlight of my day. Phil, you are an amazing Astronomer and a great person!
Everytime a GRB rings a black hole gets its wings!
Have a cookie
+robertethanbowman If I shout 'I don't believe in black holes' does a black hole evaporate away?
bruh
+robertethanbowman well got it's wings million of years ago.
+Gareth Dean No one is getting the reference to "It's a Wonderful Life" where Zuzu says "Every time a bell rings an angels gets its wings"?
Just wanted to say thank you for creating such great content. the crash course channel is in my top 10 youtube channels, and as a lover of the skies and believer in human expansion into space, I am greatly enjoying the astronomy series.
Moral of astronomy: everything explodes 😂
You gave an overview of your video at the end! I looooove it!!!
me:
"hey look miniladd posted a fallout 4 video!"
*then looks to the next video down*
"A NEW CRASH COURSE ASTRONOMY?!?!?! ALTKJNSDTL;KJM;LYKJM.LKTMYA;SdkJTA;KLJYLKMAYLKM"
+Total Unknown Me too lol
I made a little pee.
wat
+Trevor Thompson LOL
+Total Unknown Lololololol
Why is the shutter speed so high? Felt a little weird
Also, I love Phil when he gets to talk for a long time about this stuff.
This chanel is AWSOME
Just discovered this.... and I am sooo in love with this course and the passion of this host!!!
I absolutely LOVE this show!!! is so interesting, I cannot wait for the next one! :D
Can this series never end? Please? I mean, space has no edge (dude no edge), so you'll never run out of material!
I'm very trigger-happy with dislikes, but I can't begin to comprehend, what kind of person would dislike this.
Also, I don't know if I said this already in some other video, but Astronomy is better than all the other Crash Course channels combined. I have never seen astronomy or even science taught in such enthusiastic and narrative manner!
I looked askance at "Cold War 'paranoia'", but not enough askance to dislike it :) He puts out great content.
Perkele!
GRBs are the most strange set of phenomena! Also the map of the gamma-ray sky is one of the most enthralling results of modern astronomy!
8:22 made me laugh so hard, Phil is awesome😂
Vow! This is definitely Phil's the most "High Energy" burst presentation of all. Enjoyed it immensely. Funniest statement "The Swift satellite sends coordinates down to earth so that more telescopes on the earth can join in on the fun" ... this was funny!
Keep making more videos, Phil!
I really love these videos! And apparently Phil really loves Hawaiian shirts! Keep up the good work!
This is my favorite CC series, and I teach AP World History and AP US History... Love me some John Green, but Phil is the man.
2:03 "Vela" in Spanish means "sail", not "watch".
Also, 26 people lost a quarter in Wyoming.
My grandpa worked as an electrical engineer on the Vela program and I interviewed him for a school project once. Thanks Crash Course Astronomy for sharing the impact that the Vela program and my grandpa had on science. All I knew before was that they never detected any nuclear bombs.
I need to go lie down now.
you made my day!
Coke is a helluva drink.
Why?
I'm going to be incredibly sad when this series ends :C The enthusiasm that Phil brings to these videos is awe inspiring.
Vela actually means Candle. Watch in Spanish is Ve or Mirar
+Jose Rosas Well, mirar is the infinitive to look. Ve I think is I am looking, or I look. I'm not sure about that one... actually, isn't that veo? Yeah... maybe it's he/she/it looks? Or the past tense I looked? I don't know....
+Roberta Tallienne Ve is the imperative form of the verb but it's not used too much beacause you can confuse it with the verb go in it's imperative form.
Vela can be candle, sail, or a form of the verb to watch (example in context: "A: Pedro, viste la película?", "P: Todavía no", "A: Vela, es muy buena")
+Fran Ugalde Right, but then it's not "watch", but rather "watch (her / feminine noun)", and it certainly wouldn't be pronounced "veeluh".
+Rauron He can't help pronunciation, he's an English speaker.
These are the best astronomy videos out there. I really appreciate his detailed and easy to comprehend explanations.
Seema, I found some other good ones!! Check this guys page out. He is an outstanding instructor!! th-cam.com/video/HgNJwg2GISs/w-d-xo.html

Quick Phil, what's SWIFT's detection level?
It's over 900!
Phil: WHAT 9000! THERE'S NO WAY THAT CAN BE RIGHT!
Phil Swift
MOAR. seriously, I love this show. So, few questions: do gamma ray bursts push these neutron stars through space? Do gamma ray bursts propel their respective galaxies through space from these huge energy emissions?
+q Locke The burst is symmetric, no net momentum.

OMG
How do you guys do to make every episode better, more interesting, and more mind blowing than the one before ?
I regularly have goosebumps watching this show, and I love that. :)
Can't wait for the episode on dark matter :D
I like his passion and energy and how he explains everything. I feel as though I gained so more knowledge than I ever have in school, in just a matter of minutes. Also he makes it more interesting perhaps it could be the fact that I often wonder about the universe so i'm more fascinated in it all.
QUAZER, BLAZAR are those not words, anymore.?
+Damstraight68 "Blazar" is a word, "quazer" is not. "Quasar" is one, though. Why are you asking?
+Damstraight68 Yes there are, they are not the same thing as GRBs but are very similar.
The post processing in this episode was some of the best so far! I lost it with the "deal with it" glasses dropped... lol
4:15 but Wyoming doesn't exist
(only joking)
Dr Phil has a unique way of presenting every episode. Keep up the good work.
iff the GRB's position was detected to be 7 billion lightyear that means tht GRB Happened even before the earth was born? isn't it ? or i m interpreting wrongly
vikas tiwari I was thinking the same, but I don't know
Yes. You weren't wrong. That GRB happened ~3 billion years before Earth
The best Crash Course series to date. Period.
This episode escalates rapidly.
that line, "the birth cries of black holes" literally gave me chills. i love this show
the hulks video bascially
Gave me the shivers multiple times in this video. Gamma-ray bursts are extremely awesome events.
20 dislikes are probably televangelists who don't believe in space .3.
+Kyle Watts Not believing in space must be one of the saddest thing in the universe
David Joffe-Hunter Indeed.
+David Joffe-Hunter truly
haha! right!
Not believing in our lord and saviour phil plait is the
saddest thing of all
Fantastic channel
The universe really doesn't want life to exist.
"In case you're wondering, YES THIS IS PRECISELY WHAT MY NIGHTMARES ARE MADE OF!"
It's worth mentioning that whenever we see a GRB that's a few billion light years away, the event happened a few billion years in the past; GRBs were much more common in that era, as I understand it.
Fascinating script and storytelling by Phil Plait.
Is it weird I feel that astronomy is the most spiritual of all fields of study? I mean I know I'll get a lot of hate if I admitted I'm someone who believes in both God and science, but I do and I feel like the more we understand space the closer we are to God. which is funny because I think people would expect the opposite.
It's astronomy that makes me believe Lovecraft was Jesus...just my opinion!
+WonderfulAkari What does "God" mean though? Whatever attributes you put on your definition, they are just something made up by humans (or you). There are numerous attributes you could give to "God", so being a person of science, you have to weigh them all equally.

Basically, you're just making things up in your mind to make yourself feel good.
hail Satan! \m/
Yup comments were as expected.
+WonderfulAkari Well, You are made of the universe, and the universe made you. So, in studying the universe, you essentially are learning more about yourself. If you consider yourself to be the universe or the universe to be you, it doesn't really matter either way, because the answer is both.
This series is a spiritual experience for me. Please don't stop it, like forever.
Vela actually means candle, or sail.
+Luis Camilo Mira means "look" if I remember correctly.
Pikuseru I was talking about the word "vela"
+Luis Camilo It would also be the 3rd person singular conjugation of the "-ar" verb
"velar" meaning to stay up or figuratively "to watch over", "to keep
vigil over&" or "to safeguard". Which makes more sense/
Gareth Dean Yea that's right, but if you just say "vela" people will only understand it as either a sail, or a candle, not as a verb.
Luis Camilo
Ah the joys of language where you can have a pair of socks and a pair of pants and yet only have three items of clothing.
Entire World has to watch this series.... May the peace be with us.
I really hope this isn't the last episode
Don't you get the chills when you say these terrifying facts? I would even imagine you standing in awe as a space interesting object/beam is aiming at you :O
Still in my mind, the most incredible about the universe, is that it has created life, and making it able to look back at itself...agree?
Finished bingeing this all the way.
The gamma ray bursts are trying to communicate! Quick, to the Devil's Tower!
It's the first day at school fellas....
Probably the best video series on TH-cam
WYOMING????
'it doesn't end, what true story ever does?' That's some deep stuff, it made me rethink much...
DUN DUN DUNNN
This is my favorite series. I get depressed sometime while watching the economy or the history series, then I come here and feel all better.
The "United Soviet Socialist Republic", huh?
This guy is such a dorkenheimer! I love it! Makes me feel like less of a dork myself.
I can't get enough of this show. This shit is making me want to change my major to a science major. My curiosity for the universe never ends. It's terrifying, exciting, and the best part is that it's humbling and grounding. After these videos I feel grateful to be able to live life and experience pleasure, pain, happiness, sadness...all of it.

crash course astronomy is always the highlight of my week
We can't see gamma rays though can we? from nasa: (remember: gamma-rays are not in the visible range of the electromagnetic spectrum so we consequently are not aware of the phenomena)
my face always lights up with glee whenever i see a new crash course astronomy video (:
Just love bill, Bob, and jeb in the bottom. Most accurate representation of astronauts.

i watch this over and over
I love Phil's enthusiasm.
