The Big Bang: Crash Course Big History #1
Vložit
- čas přidán 22. 06. 2024
- In which John Green, Hank Green, and Emily Graslie teach you about, well, everything. Big History is the history of everything. We're going to start with the Big Bang, take you right through all of history (recorded and otherwise), and even talk a little bit about the future. It is going to be awesome. In the awe-inspiring sense of the word awesome. In this episode, we walk you through the start of everything: The Big Bang. We'll look at how the universe unfolded at its very beginning, and how everything in the universe that we know today came into being. So that's kind of a big deal, right?

it's somehow mindblowing that humans created a math, that explains circumstances that we cannot comprehend.
VIII Maus Which is math.
Can I just say this channel is such a gift to the world , you are allowing so many people to become educated and enlightened all for free , thank you.
This is John Green?! The man who wrote "The Fault in Our Stars"?!?!!!!? I've watched his videos for years and I had no clue. Holy shit!!
+DreamOfTitans was that book any good?
+ho disperatilor Yes. You will certainly love it, because it's all happiness. I swear you will not even shed a single tear.
+Ada Barcohen Oh of course dear. There is nothing wrong with sharing your opinions. Just remember to always read with an open mind. :)
+DreamOfTitans This is the SAME John Green?!? I agree 100% I never knew!
+DreamOfTitans He talks about the books in his videos. How did you not know? XD
"Oh, my goodness! This is nuts! How did we get trees?!" is actually a thought I have pretty much weekly. Thanks, John Green.
CZcams has better crossovers than the avengers
The thing I like the most about this is that I can pause it. I can't pause my teachers to take notes. :/
+Professor Nerble Haha this is why I don't attend Cellular Biology- my university records the lectures. I'll even slow it down if I can't follow.
and you can impress your teacher with all of the KNOWDLEGE that you have acquaired from youtube
dont tell them the last part
Yamikaiba123
Exactly
Gun
"how did we get TREES??!?!!" I can't stop laughing omfg
Thank you! I was hoping someone else would get a kick out of that
Well I can tell you trees existed just as how the humans exist well so with the natural phenomenon of the "big bang" so no one really can explain it that well but I can assure you that Earth in our own Solar System has the resources support trees
i just needed to pause for about ten minutes and fully comprehend the fact that if something is "13.8 billion light years away, we're looking at the light that left it 13.8 billion years ago". that's incredible!!
That's not really true... the entire OBSERVABLE universe is 90 billion light years in diameter, and not only do we not always see the light coming from it, but it is definitely not 90 billion-year-old light. Their statement would be true if the universe was static.
Shredder 9652 everything you said there was not true. like I don't even know where to start with the inaccuracies!!
he's right, space itself is expanding, so we can actually detect light from objects that were once close, but are now up to around 45.7 billion light years away(this is the radius of the observable universe) double would give the diameter of about 98 Billion ly
Isabella Crawford IKR! Stuff like that is why i'm such a huge science nerd.
Well the universe is expanding so you need to calculate the light you see to be sure that it came 13 billion years ago no light years ago.
If the Emmy's gave Emmy's to CZcams shows you guys would have earned it.
The Streamys do that...sadly, they don't have a category for educational series.
They did give an Emmy to The Lizzy Bennet Diaries which Hank Green was a part of.
Joshua Smith
That also won a couple of Streamys :)
Perhaps we should start Emmys for youtube... we'll call them the Yummies! (trademark!)
David Ruiz-Tijerina
Again...Streamys XD
I didn't understand anything but at least I heard all of the words.
“The Universe is under no obligation to make sense to you.”
― Neil deGrasse Tyson
That basically means we were never meant to exits we are just some glitches in the univese.
That’s his opinion
haha yes
-FUN MEMES- We’re not “glitches”, we’re a simple bi product of natural phenomena.
@@-funmemes-9759 yup
Am I the only one who pauses the intro every scene to read the little bubbles?
Nope
+Robin Gwak No of course not. Is that the obvious answer you wanted to hear?
+Robin Gwak i did it too and saw that at 1:26 on the left there's The Sovereign from Mass Effect
+Robin Gwak Did you see the Mass Effect Reaper in the first segment :)
+Robin Gwak yes you are the only one who does that...must be lonely

Who the f is Hank?
Sorry, but that just doesn't seem to get old for me.
Impractical Fishermen Hank is a brand of soda pop, only found in the depths of a child's subconscious.
Brook Geisler That child must be a freaking genius... :O
unbelievably awesome?
Great video but i cant wait for the comments by the creationists
"Everything. *Everything* is one billionth of the matter created in the big bang."
I cried. I literally treared up at that point. This is far beyond beautiful.
It gives me the chills, when John Green describes the chronological scale. It makes me think, "We haven't been here that long." Nature is beautiful and is humbling to note that this is the best explanation we have: It is called Science. And whether you like it or not, it is here to stay.
5000 Fahrenheit is 2760 Celsius for all you normal people out there
+TheDylarianGamer
3033.15 Kelvin for me too.
+Don the first finally.. A kelvin guy
Thank you
Thank you
***** Because every country but the USA uses Celsius
Videos like this shake me to the core. They make you feel like you are beyond nothing and nothing beyond that. And I say that with nothing but humility not negativity. 13.8 billion years ago? An atom sized beginning? The universe itself will one day die? 😔😌🙂😁 Thanks John and Hank.
The answer to your question:
42
This comment has exactly 42 likes.. coincidence? I think not.
I feel sorry for the people who don't get the reference
Dont let the White mice get you now :)
Mugdha Kurkure yeah, I feel sorry for myself
What was the question again?
"Infinity war is the most ambitious crossover in history"
*shows video*
I'm feeling like my life has been a lie..... been watching crash course for so many months, from psy to world history... and only today that I realise that John and Hank are two different people....!!!!!!!!!!!
anyway, both of you are fantastic!! studying has never been this fun!! thankyouthankyouthankyouthankyou
This is one of the most amazing things I've ever seen; this looks like it'll easily be my favorite Crash Course so far, which is saying a lot. Thank you John, Hank, and all of the Crash Course team. I'll be eagerly awaiting the next episode down here in Mexico.
Earth: See? I told you we should have asked for directions after the Big Bang!
Milky Way: SHUT UP!
The big bang happened because the universe divided by 0
nice resolution, ha 🦄
It was just a joke dude, I bet youre fun at parties :P
*smart people hate being in the same place with stupid people.*
You must hate being with yourself
Anıl Ertürk Woah youre a total nutjob. Please block me too so we can never interact again
I dont get the joke :(
Years after sporadically watching crash course series (primarily history) and I completely missed this particular series!
A history-science course featuring both Green brothers as hosts? Where have I been?
Just found it today,
Ive been living a lie,
Great, look forward to seeing more
I look forward to see the whole "god created world" comments actually.
but... the big bang theory doesn't prove nor disprove anything religious... 'cept for the fools that think the world is a wee lil' baby planet that's 6000 years old, but then it'd be a volcanic disaster of a planet
DeathdwarfRising Why? Both sides are pathetic and annoying and make our world a lesser place.
Little suggestion? Instead of using Fahrenheit, a barbaric unit of measurement, why don't we use Kelvin? Or Celsius?
I would actually prefer if they used all three so it doesn't leave anyone confused and the majority of viewers will learn and understand the Kelvin scale. But I wouldn't go as far as to call Fahrenheit barbaric. It's just centered around brine instead of fresh water.
Rebecca98463 Yes but every salty water has different concentrations of salt. Therefore I conclude that Fahrenheit is not standart or scientific.
Tolga Elbay Err... so your argument is that since we find water with different saturation levels in nature, using brine is some how unscientific? I don't see your logic here. It seems like you just have an odd distain for Fahrenheit and you're grasping at anything you can to undermine it as a legitimate scale for measuring temperature.
once we get a temperature with more than 3 zeroes, i don't think it matters (outside of actual research) what temperature scale you use. 1,000 kelvin will kill you instantly, 1,000 celcius will kill you instantly, 1,000 fahrenheit will kill you instantly.
Rebecca98463 I didn't know brine boils at 100 degrees Fahrenheit.
Hey Green brothers, I've been following many of your playlists now, while doing some aware discovery of myself and the world. I feel its safe for me to say that you two are truly warriors in the fight of bringing human kind to a new height. You deserve all the success that you've got, and in my opinion, MUCH more than that. Your channel has been an inspiration to me, and has led me to seek the answers of questions I didn't even bother to ask myself before, and for that (lighting up my curiosity), I will be ever thankful.
excellent intro episode. i'm fully compelled to watch the rest.
i especially love how the meaning of "big history" is tied together at the very end -- in itself, very compelling.
peace and thanks
WHOOOOOO!!!
This episode, sadly, did not have brains on it
I'm looking forward to seeing your appearances.
nice to finally see an episode of crash course starring BOTH the brothers, rather than just one of them
This video made me realize how stupid I am ;-;
+dipper pines You're not stupid. When you say that what's addressed in this video are lies; THEN you're stupid!
+OnionChoppingNinja How do you know that Dipper agrees with the video. Dipper could refuse to classify the information as truth. He obviously watched it and you OnionChoppingNinja gave him the ultimatum of believe the video because its truthful or disbelieve the video and you are dumb; after watching the video Dipper, "realizes how stupid I am " so he believes its all lies.
Lol😄
You are not stupid, this "science" stuff is just smart.
+dipper pines nope.. "stupid" is not being interested - or questioning- things around you. Its not an IQ thing either, its an attitude of being willfully ignorant
Can I request a Crash course series on physics? thank you
They're making it!:)
+Charles Smith Seriously? yes best news of the day :)
+Jeffery Kelsch Your wish has been granted.
I want more economics videos. Narrated by either Hank or the original people, if possible.
I'm hearing you say "was created" when you should be saying "formed."
Hank used the word "designed" in the video, too. I'm pretty sure we'll disagree on how relevant terms like creation and design are to the beginning of the universe (I am a creationist Christian) but I agree with you that they certainly shouldn't be using those words to describe the big bang theory. I hear science presenters on CZcams and elsewhere use them all the time though, particularly in biology (e.g. describing an organ as designed to function in a particular way).
KunamaElgar "Design" is a nice word because it captures how beautiful some aspects of life are and how intricately constructed certain organs etc. are. I don't think there's any problem for atheists to use this word if they appreciate that the "designer" was the process of natural selection which is able to fine tune anything based on environmental factors.
It's simply a poetic anthropomorphism of a blind force of nature. It's not that uncommon a thing. People anthropomorphise inanimate things all the time.
Chalk it up to entertainment purposes. It may not be the best for science presentation, but using different words and granting them loose meanings is better for entertainment and presentation. It's similar to when you were writing in school and the teacher told you not to use a particular word too frequently and handed you a thesaurus.
Actually, The Cosmological argument shows us that a non-physical agent is the most likely cause of the big bang. Even if a multiverse exists, Vilenkin et al. have shown that there must still be an absolute beginning and therefore the philosophical argumentation still applies.
They are synonyms. Using creation only bothers you because someone can say, "see he said created". When you form something, you create it.
>inb4 flame war
Couldn't think of anything else to comment.
You and a lot of other people, including me.
Then why bother commenting?
Noah Medel
Why bother replying?
Why not.
First 40k Dreadnoughts now a reaper from Mass-Effect? God I love this channel and it`s references!
Yes please, tell us, brother.
i've read all of john green's books. since fifth grade (I'm in 8th rn) I have read his books. just now, I realized that this man and the author are the same person. he provided entertainment and made sure I passed my science tests dang!
In his book "A Brief History of Time" Stephen Hawking said that since no information could have survived through the Big Bang, there's no way anyone could ever know what was there no matter how hard they tried. So theorizing about it is completely pointless and we just say there wasn't anything at all. It's similar to people questioning if God exists, if you start with the assumption that we can never know for certain then by definition it's a question that is impossible to answer, and so many people just say there isn't one and leave it at that.
I wouldn't say theorizing is pointless. Our lives also have little to no affect on the universe, but they're not pointless, are they?
But then you need to consider, nothing material or spacious can exist ex nihilio (out of nothing). Something had to create what we live in today and because of that, its impossible to say that the big bang created itself or from nothing.
drew gillum ***** By pointless I mean you will definitely not get an answer that can be proven. If you want to try, go ahead, but you can't prove that you're correct. Sure someone can say that there is a life beyond all this where there's no pain or suffering, but someone else can say that there's a life beyond this that is nothing but pain, and someone else can say that there is no life beyond this. All three are equally valid, and therefor cancel each other out leaving you back where you started. So yeah, pointless to anyone who won't instantly reject any idea that disagrees with their ideas in any way.
Don Mattrick Except that the concept of 'nothing', what we think of as such, might actually not exist. Then it is perfectly possible for the universe to exist without anything or anyone prior.
Besides that, we don't know if something can come from nothing. We have no experience with 'nothing', so we do not know if the least amount of properties 'anything' can have would not automatically create a universe.
So, it's a flawed argument which comes down to 'i don't know, but it must be x'. That's not how things work
Did you study the evidence we have now?
You're doing this one together? ! Awesome.
They have been doing this on bill gates big idea channel.
unostriker What do you mean?

From Crash Course's wikipedia page:
"In May 2014, John Green mentioned an upcoming 10-episode Crash Course season on Big History, funded by a grant from one of Bill Gates' organizations.[25] The series would be aired on its own channel, entitled "Big History Project," rather than the Crash Course channel."
Awesome :) Still waiting for Tim Cook and the other Apple moguls to donate to things like this.
It's already been two years?! Jeez.
I, too, jizz.
Oh my God! How did we get TREE?!
5:00 ok scaling the years down was REALLY helpful
Common trick; makes everything easier to comprehend. Has the unfortunate side effect of causing the explosion of listeners' brains.
Well it's just not helpful when physicists say the universe is 13.7 billion years old and the earth is 4 billion. Massive numbers like those are equally unhelpful.
***** For even smaller numbers, I think MinutePhysics did one where they compressed all of history into a day (24 hours).
I agree. Scaling down is one of the most helpful things when learning about this stuff. Have you watched Cosmos? They compressed everything into one year. Had a great calendar and everything. Though personally, I think I might actually prefer the 13 year thing to one year, because it means having to use fewer fractions of seconds, which can also get a little difficult to comprehend. Tremendously small is just as hard as tremendously huge.
Seasonal reminder that I want a Physics Crash Course.
"The thing that was banging.... " - John Green 2014
At 6:13
Well, my brain just imploded.
I can already hear the rumbles of the flame war to come........
Brace your selves.
Videos like this always leave me with more questions than they answer - which is good. One of the things I don't get is why were only Helium and Hydrogen (and apparently a little bit of Lithium) around after the bang? Surely the heat and pressures produced at that event would be capable of producing anything a sun could?
I'm not a hundred percent sure on this, but I'd guess the expansion of the universe was too rapid for fusion to take place.
Kevin Baker Yeah, it's a question of time. The electrons were still trying to find hydrogen and helium nuclei to pair up with (I *believe* once they were all paired up, that's when the free electrons stopped absorbing all energy and the universe became transparent for the first time, and the radiations stopped getting trapped and re-radiated and was allowed to run free - hence Cosmic Background Radiation), nuclear fusion is a much more probabilistic process.
The early universe was FAR too hot for atoms to exist. Just after inflation there was a quark-gluon plasma, basically a sea of semi-free quarks and gluons, because there was too much energy for these quarks to form together to create hadrons like protons and neutrons. One the universe had cooled down enough for atoms to even exist, there wasn't enough pressure and more for fusion to take place (remember, the universe is expanding; everything is being pulled apart). It was only when a lot of atoms coalesced together could stars form, and therefore only then that higher atoms could be made.
It essentially boils down to the nitty gritty details. Some reactions that happen in stars need a catalyst to have a decent chance of happening, and others have intermediate steps where intermediate products have to decay before the reaction can continue.
The CNO cycle and the P-P chain which occur in stars have bottlenecks, which are so restrictive that it makes reactions really slow, to the extent that it takes stars millions (if burning with the CNO cycle) to billions (PP chain only) to burn out. The CNO chain requires elements with half lives measured in tens of minutes to decay through the weak interaction as an intermediate step, which is higher than the time that was available for big bang nucleosynthesis to happen. More crucially, it needs carbon as a catalyst which didn't exist at the time.
The P-P chain, where two single protons fuse into deuterium, is an incredibly rare process no matter how high your temperature is because it needs the weak nuclear force to cause one of the two protons to turn into a neutron in the short time during which the two protons are combined.
The reason that there were fusion reactions available at all was that the big bang created free protons and free neutrons in roughly equal ammounts, which is a rather atypical situation because free unbound neutrons will decay to protons and electrons within a fairly short ammount of time. This meant a lot of deuterium and tritium being produced, and that mostly burned into the helium and lithium. But otherwise you really need more time for fusion reactions to happen if the only thing you're starting with is hydrogen and you have no catalyst available.
***** If you look carefully at you answer you will notice that it doesn't actually explain anything because it doesn't say why there wasn't a time between "too hot" and "too cold" that was just right for metals to form but other answers before yours took care of that. I'm just saying this because yours is actually the "explanation" that one will hear more often and it always frustrated me that it actually explained nothing at all.
+CrashCourse i am i they only one who wants crash course genetics? :-P
I loved this series so much. I watched it all when I was in Fort Bliss. Rewatching it again just because.
I can't wait to see Emily Graslie on this channel!!!
I know right isn't she awesome!
You dont 'have to wait!! You can see her video and the rest of this series on channel "Big History Project"
She is the most disturbing person in the group...I surely hope she does not make an appearance...
What the heck, she is not the most disturbing person in the group I'll have you know she does a great job of presenting information and you don't like her then don't watch the video man, sheesh!
JJ Klaus You might not like her presentation style, but "disturbing" seems a bit excessive.
I like the back and forth of both brothers. Your styles compliment each other and create a wider appeal. This is one of your best episodes. Thank you and well done.
This is so genuinely interesting, I love it
"you are a somewhat firm bag of energy."

Great instalment! Very ambitious, feeling inspired by the cosmos with NDT and will be staying tuned!
Please use Celsius though =P
Please no religious flamewar.
*blows out fire on Molotov* awwwwww
So...no mob? What am I going to do with all these pitchforks?
Dude this is the internet. There will always (and I mean ALWAYS) be flamewars.
I agree! Arguing over whether Hank or John is the best isn't leading anywhere!
*BURRN THE WITCH! BURN THE WITCH!!!*
Thank you guys so much for teaching youtubers and even regular people about so many different topics in a bunch of different categories. I love your channel and hope that you guys keep up the great work!!!
after watching soooo many hank green videos, watching John green feels like a wierd and yet strangely familiar alternate universe version of youtube.
Cosmic stuff makes me cry. I don't know if that's just my brain's way of coping with the vastness of it all but I get misty every time. Especially NASA's "picture of the day".
bloocheez3 oh, I feel exactly the same. I almost cried SO MANY TIMES when watching the astronomy Crash Course

Best crossover ever! The Green brothers wohoo
Technically speaking the big bang happened right where your sitting. My new plan for world domination
1. Tell all scientists that I have found where the big bang was
2. Open a museum there
3. Charge admission
4. ???
5. PROFFIT!!
David Jameson That was intentional. I want the F to be pronounced longer. Like this
Proffffffffffffffffffffffffffffffffffffffffffffffffffffit
Step 4 is realize that you learned this from scientists who would laugh at you for charging admission. And regretting that you didn't simply capitalize on the foolish and uneducated masses like most good business men.
+GrammatizatoR technically speaking where you're sitting was part of the big bang, not the origin of it, so it didn't happen right where you were sitting because you weren't formed yet.
God.

I, VINCE MCMAHON, AM SINGLE HANDEDLY RESPONSIBLE FOR THE CREATION OF THE ENTIRE UNIVERSE, AUSTIN!
Why oh WHY every one of these videos has to end up in a "religion vs science" debate? I don't see the point. It's not even like you are going to change someone else's opinion to begin with and at the end of the day, both sides will look like screaming kids while sensible religious and atheist people are just watching the video.
Something to pass the time and make us feel smarter about ourselves. People should grasp that religious belief (or lack thereof) does not equal stupidity.
I'm grateful you asked that question Ch1, because I don't think you're the only one wondering about this. There are many people wondering this very same thing and in much the same way. Intrinisic in this question is the idea that religion and science are mutually exclusive. I would propose another way to look at this.
The general presumption is that educated and scientifically-minded people would fall on the science side of the debate and the mis-guided, weak-minded, ignorant, self-dilluded (let's just say it "weirdos") would fall on the religious side.
However, let's just scrap that word "religion" for a moment, because it conjurs too many unattractive conotations to be useful. What we are really refering to is those people who believe in a Creator (a personal intelligence). Also, when you're referring to science, I think you are referring to a lack of a creator--AKA naturalism.
If we ask the same question another way "Why oh WHY every one of these videos has to end up in a "CREATION vs NATURALISM" debate?", the answer begins to reveal itself.
When a video like this is posted, and it seeks to educate people on the "facts" of the Big Bang, it at the same time, undermines the Creator of the Creation. It gives a new basis for the existence of humanity (no reason whatsoever). It give you a distinctly different view of morality (God's will vs moral relativism). It gives you a different view of history in general.
I do not consider myself ignorant on the topic of evolution, science or the big bang. I was taught them from grade school through university. I was trained how to teach evolution. People continue to teach evolution as a fact, but this "fact" is based on a foundation of smoke and mirrors. As a scientifically literate person who has a thorough understanding of evolution, I reject the theory of evolution. I do not think it is SCIENCE. I think it is a very creative attempt to explain the theory of naturalism.
There are many scientifically literate people, who have an in-depth understanding of the theory of evolution, and yet they would agree with me the there is no evidence supporting the most fundamental elements of the big bang theory. Where did the energy for the big bang come from? What caused it to bang? Why does the matter in our universe move in different directions and with different angular momentums? The theories for this are called "Theoretical" because no one can reproduce these events. They are not science. They are ONLY Speculation.
Well written, but very "facepalm-ish".
The very concept of evolution or the big bang doesn't undermine the concept of a creator. There are many concepts of creator to be bothered to stick to one.
Also, by the mere definition of science, it means that you can formulate a theory based on some evidence. A speculation it's science if it's well founded. Might be false but with the evidence presented, the theory can stand until proven wrong.
Also, who cares? AGAIN why bother to try and change other people's opinions when it seems that you got your own and stuck with it? It's a plain waste of time. But I guess this is one of those cases.
So whatever man, suit yourself with that long (and non-sensical) answer.
(also: smoke and mirrors? then what base do people who deny science are doing they statements, and I'm not even atheist... you know what? Don't answer, you can believe whatever you want...)
Because Trolls love religion
hahaha totally agree with you!
1:31 ''world war 3 will be faught by the radiant and the dire''
+Angela Candy was looking for this comment
"Hey, I'm not John" I love that opening
I love how, even here, they managed to put in a Mongoltage. xD
Hank and John should make educational videos together more often :) Whatever people say, the history of the Universe is as much inspirational as it is scientific. Thank you for the wonderful video, guys
Seeing them both in the same video and wanting dance for joy
Lol, the Mongols!
lol i saw that episode in 6th grade at school and that was all my social studied class talked about for a week. This show literary made a whole bunch of 12 year olds laugh and learn at the same time and not be cringy
I love the collaborative nature of this. Switching between John and Hank, their own flavor and enthusiasm mixing together so well. I think I'm going to REALLY enjoy this series.
Also, it pointed me to the Big History Project, which is worth watching on it's own merits, but especially so that they are collaborating with the Crash Course Crew. Well done on all fronts. I hope this is just the first to come of many big, educational collaborations within the Nerdfighter community and beyond.
Keep them coming.
Biggest unanswered question of the Big Bang: *why* was there slightly more matter than antimatter in the original starting condition? Why weren't there equal quantities of matter and antimatter, resulting in total annihilation? Ie., why was the original universe "lumpy" and not uniform?
Yup, and I for one, don't have a damn clue.
Probably because nature made it that way that our universe would have things made of matter, i believe in multiverses and i think some of them are made of antimatter and of course if multiverses would exist, then there would be total universe annihilations also. But too bad we would never know the real answer, because we never can have antimatter in our universe and if there were multiverses, then travelling between universes is of course impossible for us, but who knows what science can reveal us.
That's the CP violation. en.m.wikipedia.org/wiki/CP_violation
MegaReinart We do have small amounts of antimatter in the Universe
William Gilliam source?
The excitement I felt when I saw Hank
so interesting this is my favourite crash course series, 2nd time watching it through. I'd love a crash course cosmology
The _"Apollo 8 mission flew to the moon, orbited, and returned to Earth without landing"_ bit makes it sound like they're still in Earth orbit.
It burned up in the atmosphere? Maybe?
A long time ago. Actually never. And also now. Nothing is nowhere. When? Never. Makes sense, right? Like I said, it didn't happen. Nothing was never anywhere. That's why it's been everywhere. It's been so everywhere you don't even need a where. You don't even need a when. That's how every it gets.
You can make a religion out of this.
*the sun is a deadly lazer
I see what you have done here and I am glad to call you friend.
I got that reference
@@fbk8004 please can u state the reference
These videos are hugely important. Thank you for doing these!
looking forward to finish the series!!!
It would be a lot easier to do history if textbooks said the big bang was the start of WW2:
When did WW2 start? A. The big bang, 13.8 B yrs ago.
Why did it start? A. The big bang.

I majored in history and it has always bothered me that we didn’t even discuss anything that happened pre writing. I’ve never heard anyone else agree with me, I feel so validated right now!
These two brothers are awesome and I hope they keep making more videos. I would Especially like to see something about the ocean.
Who is here after the coursera course on big history !!
I'm so pissed off at ignorant people that say: "Omg! Like, how can you believe in science if you're a christian!?!1!" Seriously, if you knew anything about christianity you'd know it does not go against science, but rather understands it in a way that makes sense to us. If it doesn't make sense to you, then I'm truly sorry, but some people really need to learn to respect other people's religions and not judge them based on the little information they have.
Also, I'm really sad that people have to turn the comments of a well-done, amazing, interesting video into an attack against christianity. It is an insult, not only to religious people, but also to John, Hank, and all of the people who participated in creating this content. Why can't we all just be a united community based on our shared love of learning? Why do people keep putting labels and criticizing people for what they believe true or not? I seriously love the community John and Hank have created, but the comments on this video make me sick.
"Omg! Like, how can you believe in science if you're a christian!?!1!" That something a lot of theists would say, yet you only complain about atheists/non-christians. You are just as bad as anybody else here.
Raidoton I'm sorry if my comment sounded rude, I just meant to say that I believe that position is wrong, no matter if it's christians, atheists, or any religion for that matter. You CAN believe in science even if your a christian, and that is something I feel most people don't understand, sadly even some christians.
no you are wrong science contradicts the bible so you can not be a Christian if you believe in basic science, you are theist if that is the case.
rountree5 Listen, I'm a christian and I'm in a catholic school. Believe me when I say, you can believe in both religion and science.
Ana Villarreal No that is called cherry picking and taking things out of your religun that was there and replacing it with scientific facts, face the fact you are a theist. Its not a bad thing.
These vids are soooo good! Thank you guys :D
AAAAA both hank and john in the same video!!!! history meets science!!!!! this is beyond awesome...its unimaginably awesome😁
i love these guys videos so yeah
Hey, where's Adam and Eve!?
(I'm joking. LOL)
Thank you.
(He's joking. LOL)
Kurdish Falcon I was thankin him for not being an idiot.

John, if you think historians do a bad job naming things, consider scientists; "Big Bang", "Global Warming", "God Particle", etc. You can bet the majority of scientists wish they could go back in time and give names that won't be so twisted and misinterpreted by people (particularly science reporters in the media and science-denying political pundits/politicians who think the scientific method is some kind of liberal conspiracy and shouldn't be taught in schools).
The Higg's boson was never named the God Partical, the big bang was originally named something closer to primordial egg, Global warming is exactly what it says on the prepackage the globe's average temperature is increasing, global warming. Now the quarks man. Up and down, top and bottom just sad strange and charm where better but top and bottom could have been named truth and beauty once upon a time .
yeah the god particle bit was how news outlets chose to call it- no scientist would ever call it that.Higgs predicted it- he should get the title for it.
Most scientists don't like the term 'God Particle' for the Higg's Boson, and it isn't used overly much. Global Warming was redacted to Global Climate Change as when the term was originally coined it was done so on older data only noting the increase of temperature, instead of the reality which is an unprecedented fluctuation in climate systems resulting in more extreme weather, not necessarily hotter weather.
Well, for the "Big Bang" I'd ask you to consider that this name was coined around the time our grandparents were in highschool. Just like the jokes from that time, probably people thought it was funny or clever back then, but now they are pretty lame. The term "god particle" was unfortunately coined by a physicist--and a Nobel laureate, no less-- in a book. This was probably intended to be controversial or grandiose, and sell a lot of books, but it is a shame that it stuck. But I assure you,in the business it is called a Higgs field.
Actually, the Big Bang was coined by Fred Hoyle, the theory's greatest opponent. He thought the theory was so ridiculous that he sarcastically compared to a big explosion, Ironically enough, that name stuck.
