So before endgame huh. I get your reference.
I find it amazing that "warm-hot" (100,000K-10,000,000K) refers to the unfathomably hot temperature range between about 180,000°F and 18,000,000°F.
"Ah yes, just a warm intergalactic bath" - the astronomer literally being vaporized
we humans really live in the coldest of temperatures available in the universe. Few people ever think about this
When I heard that, my brain broke. That's hotter than stars!!! 🤯 How!? 🤔 Went to Google... Didn't find much... Something about gravitational energy is all I could find, and it's only speculation from an unreliable source. 🧐
I mean, there is a minimum for temperature just 273.15°C below the freezing point of water (1atm) but no temperature maximum. The hottest temperatures recorded (I think) reach the billions Kelvin 🤔. So yeah, 10'000'000 is just "hot" 😋.
Yeah, it's a different world, isn't it? Well, not a world, really ... 🤔 But it does put global warming to shame. 🥵
This kinda blows my mind. It takes some genius ingenuity for scientist to do what they've done in every field for specifically the last 20 years. But Astronomy and physics are making ridiculously impressive strides, which only turns into more questions to be asked lol. When will it ever end?
"Regular baryonic matter" that's rich coming from the 5%
underrated comment.
Regular baryonic matter is the caucasian of matter. So everything else is a minority matter obviously. Especially that dark matter squatting outside our gated galaxy.
lolol.

This was absolutely my favorite of your videos! So many amazing analysis and thesis connected together with a galactic chance of something not even understood that solved a different problem! Look forward to hearing when scientists find out something so interesting as what causes these bursts of radio waves. Also looking forward to more info on the other 95%!
Damn, This video encouraged me to read about the Lyman-alpha series but ended up learning the Bohr model of the atom, the Rydberg formula,the Lyman series, the balmer series and also the Peschen series. I'm currently learning about the Lagrangian of a spinors field which satisfies the Dirac equation. I can finally appreciate the beauty of the Lyman alpha forest. Thanks Veritasium
"A Quasar's luminosity can be thousands of times that of whole galaxies"

@@PyPylia any light theme tbh. Quasars have nothing on them
You would NOT want a Quasar in your bathroom, even if it was only a microscopic part of one outputting 60W of power... At least there'd be no germs anywhere, but the lingering ionizing radioactivity would be bad news.

Lmao yeah cant relate
Even if the matter doesn't do anything, they still do something. Same is for u and me
The difference between scientists and non-scientists was something I had to learn the hard way coming out of college. I would correct people or provide additional information, thinking that it was interesting and would lead to discussion or a better understanding. Most people just found it as an attack on their understanding or an attempt to correct them to show off. Not really my intent. I generally like it when I'm corrected because it means something I thought I understood could be described better or was misleading.
Good for you on liking to be corrected. I only like it sometimes in intellectual discussions, but once you convince me I usually like it.
Now if only we could have this same ideology with politicians around the world
Dont make dumb ppl change your way, we need more ppl like you
Scientists with jobs understand that they need to be right to be taken serious by normal people. That's why they chose to be wrong and say they are right. But it's "ok" because science is "always wrong". Halting science as a scientist is totally worth it, you need the job after all.
@@mreese8764 I... what?
That final message is actually so true. When he said that the WHIM added up to the 5% I was genuinely disappointed, because it meant there wasn’t any further chance for any extra matter that might have interesting properties.
That remains to be seen. There is still the matter of that pesky 95% that remains to be explained ;) You might get your weird matter anyways!

kind of a flex, dont ya think
Unquestioning acceptance of this kind of cosmic fairy tale let's you be all smug and self congratulatory when talking down to your audience.
That's the problem with science, they still don't have the main answers to a lot of different things like what is dark energy and what is dark matter and what is gravity and why do particles exist as they do and why do they have a wave particle duality and why does the Dual slit experiment give the results that it does shooting one Photon at a time. There's women on this planet with an additional cone cell in their eye and they're able to see an additional color oh, we can't even comprehend any other color than what we see already. If our brains are that restricted, restricted to basically having to experience something before understanding it, then we're not going to have a lot of answers soon
At this moment in time everything is faith-based, no one knows as to why existence exists and not even scientists do.
@@tuberroot1112 This is literally the opposite of unquestioning acceptance.
@@tuberroot1112 you sound just about as smart as a tuber root. If they had unquestioning acceptance they would have accepted the simulations decades ago as truth. But they questioned it until they confirmed it with hard data.

One very underrated takeaway from this is that it is often easy to think that all the big discoveries have already been made and now most discovery is of smaller things. A moment's thought about basically anything will reassure you that this is far from true, but it's especially reassuring to note that FRBs, hugely powerful radio source events that happen quite frequently in the universe, have only been known about for a scant 13 years. In the history of science, that's really a blink, and it means that we are still very actively discovering the really big stuff. We are FAR from done. :-)
Thank you so much for uploading this video. It is helping me get through the pandemic!
"Warm-hot" is such a hilariously modest term to refer to millions of Kelvin. Like, "warm-hot" is how I would refer to the temperature of my coffee when it's been in my mug for a couple of minutes and isn't quite "hot" anymore. Physics and astronomy operate on such a fundamentally different scale you can't even wrap your mind around it!
Yeah u literally can’t wrap your mind around it (unlesss)
Well he is referring to it that way because the name actually contains warm-hot and the reason its called warm-hot is that in comparison to other temperatures we know of in the universe are way hotter than millions of kelvin.
It is not in comparison to your coffee for a reason, coffee isn't one of the hottest things in the universe, you may thing warm-hot is similar to how you would describe your coffee but that is because you are comparing it to how you feel it through the nerves in your hands. And to end my rebuttal, I have to say it, physics and astronomy operate on such a fundamentally different scale that you can't even wrap your mind around it! Lol, disappointed in some people, that are so sure they are right that they wont even consider being wrong...think before you speak.
And just for some comparison to help you out, one of the hottest things in the universe i'm talking about is about 4000000000255.372 kelvin, just a tad more than 1 million, in fact, its 4 billion since you wouldn't be able to tell. And things con go much much much hotter. In fact, temperatures can go up to 10 to the 32nd power of kelvin, this is the hottest because in the physics we understand today, once it gets any hotter, conventional physics just doesn’t work. Weird things will occur that don't we dont understand currently. Gravitational force becomes as strong as the three other natural forces (electromagnetism and the strong and weak nuclear forces), and they will merge together into one unified force. Understanding how this happens is referred to as the “theory of everything” which is the holy grail of modern theoretical physics…something that we currently don’t understand, as said multiple times before.
I figure I should try to comment here before someone replies in a less polite fashion. I believe the original post was intended to be appreciative of a bit of terminology that is humorous when juxtaposed with ordinary human life, not an attack against the temperature classifications employed by astronomers. If someone were to be leveling insults against our dear scientist friends, I'd be right behind you with the proverbial pitchforks and cold, dark torches, but I don't think that response is warranted here. As a side note, 4000000000255.372 is on the order of 10^12, if I have counted correctly, which would place it safely in the trillions. Anyway, I'll stop taking up all of your time. Cheers.

I wrote a clock program in C on my 8088 IBM PC. The computer was not fast enough to draw the digits with each second, so I had to write routines to change a 1 to a 2, 2 to a 3, etc, by era ing and adding digit segments. Changes on the hour, dealing with possibly four digits changing were something to behold. I wrote the program, because on the original Macintosh, there was a clock where one digit morphed into the next. . . something way beyond my capability. But, manipulating x,y coordinates on the screen was instructive, and played a good part in some of my later software efforts.

Best one of your vlogs in a good while. Loved the slightly (deeper? more advanced?) explanation.
I've watched you since the "great carnivorous clown con" began, and you are into the truth. Your statement, "scientists would rather be wrong" is dead on target. I've been an amateur scientist all my life, and this is something I've followed with great interest, since my teens, and the "realization" most of the universe wasn't at all visible, and not understanding at all, in the late sixties.

under that line of thinking, Black holes cannot be "swallowing" or "consuming" Matter. If we calculate the 5% of the universe should be baryonic matter, and we can now run calculations that match this, then all of the barionic matter that is drawn into a black hole must be emitted somewhere in the known universe, or we would see that baryonic matter had reduced from 5%.

To me, this is groundbreaking and very exciting! You can only discover something like this once.
I still remember the excitement I felt when it was first reported that the universe was 13.7 billion years old (13.8 as it turned out).
I think things like the number of stars in the galaxy, the age of the earth, the distance to the sun, but also the density of matter in interstellar space are fundamental in our mental picture of the universe and should be taught in schools.

Well, Derek is describing a romanticized self flattering science, not actual reality. Physicists love to be right and hate to be wrong but it's true that something that violates known laws is very valuable. But that's a further failing of human science because we have such gems like ball lightning and cosmic jets or the fluctuations in G, a socalled constant but people in science are still people subject to the trappings of psychology and personality flaws so 'science' doesn't look at those issues. They are in denial. Dismayed by the far reaching inconvenience. People are so petty in all walks of life. Human science is very far from the ideal he claims here. Some few are rational. And the more taxing the subject the fewer it is. Let me see a show of hands who can handle the UFO topic for instance. And by UFO I of course mean visiting ET ships. Even though the US navy is essentially admitting regular contact incidents nowadays. So don't give me that crap that 'science' is rational. It's people.

I am too much willing to watch videos which is related to science but as i m Indian . I can only understand 50 % of ur language. But still enjoying too much . I love to see ur videos . Coz interest in science.
@Steven Victor Neiman 😋😍
Pronunciation can be bit tricky if you are not accustomed to hearing it. Have you tried subtitles they seem to work for me. Speaking as a fellow Indian
Awww .. the last part hit home for me.... I was blown away by the entire video but the last did it for at so many levels
One of your best for me, I learned so much: The Lyman - alpha forest, the WHIM, whistlers; well done. More like this please
why did i click on “More”
@@apoorv-vu4pd Because you are a more - on?.... or maybe because it was like, 5 a.m., lol.
Magnatar sounds like a badass, villain star.
Considering one could destroy the galaxy in an instant with one unlucky pass, yah... They are a pretty good villain.
@@skurblord3401 I don't know about destroying an entire galaxy
Destroying a galaxy? No. Our solar system? Yeah, it would
Or a kickass band from the 80's, Pat Magnetar.
A Pokemon probably?
When I watch your videos, I just see that How the Education system failed us to think critically. I am a Physics Graduate and we were just taught to fill the Exam paper...I have Learnt much more from Internet and CZcamsr like You.
Just Fantastic. Thank You for being here.
Excellent video, as a scientist I totally agree with your summary 👍🚀
7 years from now this will be in everyone's recommended section.
And this comment will have over 300 likes
A whole new generation of young existentially angsty kids 😆
LOL!
This comment made me think the video was made 7 years ago
Perhaps. . .
How do people come up with this stuff and how can they be the same species as Flatearthers?
and creationists and trumpies.
Flat earthers' just have a mutation that makes them stupid
@@casualbeluga2724 It do be like that
We're still looking for the flatearthers' intelligence in the warm-hot space goo. The REAL reason why scientists are searching the universe.
Also because life has different paths creating different minds, some get more involved in science, others might not even heard therefore care of these things, resulting in different beliefs that they protect thus protecting their taken path, knowledge sharing and conversation should help us find our ways, or we could just roast human intelligence alone if that's less of complicated answer to you...
I read about the Lyman-alpha forest years ago, but I didn't get it until now. Excellent explanation!
The best part of the video is
‘
The difference between scientist and non-scientist is non scientists strive to be right, they like things to be the way they expect them. But scientists on the other hand, They want things to work not the way the expect them to be. Because that is the way they got new clues and evolve knowledge.

Me: Finally i made a whole day without Anxiety
Veritasium: “Did you know half the universe was missing??”
Imagine how we felt knowing about the missing Baryon problem before it was resolved. :P
Me: Finally lost 10% of the weight.
Veritasium: “Did you know half the universe was missing??”
After I came home, I eventually found the missing half of my universe asleep under my bed.
I need to put some kinda skirting board around that, I guess.
But I only shame myself when I worry.
I totally own the can-opener.
hey I got some news for you buddy, dark matter and dark energy make up 95% of the universe.... and they are missing as well
@@SpencerTwiddy that is what baffles me, how & why the universe can create something that's also nothing
"Half the universe is missing..."
"did you check behind the fridge?"
Turns out it was all a lot of dihydrogen monoxide located in the sub-refrigerator region.
idk i think its under the drier
I looked under the sofa cushions - nothing!
have you looked at the lost and found desk?
@@sirBrouwer i asked but but god said that they already pawend the stuff
Excellent illustration, thank you.
Exceptional presentation containing amazing information! The whole universe as we see it is only one fifth of the 5% of the total mass.. that is 1% of the total... wow!
So basically, Veritasium is a huge nerd.
*i like it.*
I don't have any friends because they are ashamed of the videos I upload. Are they really that bad, dear ver
Don't read my username.
@@AxxLAfriku They are very bad.
@@hydrogenatom4624 nice self advertising there
@@junkandgunk This was an entire thread full of self-promotion before you commented.
Wow amazing, when you mentioned that lightning emits broad spectrum radio waves I had a flashback of when I was a kid tuning an old transistor radio to a frequency with just static. There happened to be a thunderstorm at that time and I could hear the pulses of radio emission from the lightning.
It just so happened that there were also thunderstorms on the other side of the planet a while back who had just finished the magnetosphere trip
@@NotSomeJustinWithoutAMoustache I think I read somewhere that in any given second there are thousands of lightning strikes occurring across the Earth. Or maybe its thousands per hour I can't remember exactly. Point is lightning is basically always striking the Earth somewhere. Or I guess travelling from the Earth to a cloud? Ok never mind I know nothing once again lol.
@@kozmosis3486 short wave "sw" on consumer radios is still filled with random stuff including lighting strikes and CMB noise..
Recently found this guy love him and his content. Can't get enough. I typically can't stand the typical CZcamsr.
In my chemistry class, we just finished a unit on ground and excited state and it’s cool hearing you talking about that stuff. Idk why, just is.
7:40 This is how *Popbob* found and griefed many large bases in *the oldest anarchy server in Minecraft* !!
Watching this makes me amazed at how we can observe a simple phenomenon like redshift and somehow apply the knowledge to calculate the missing matter in the universe. Like damn, humans are really smart
A few of them are anyway
@@kozmosis3486 For real. There’s no way I would’ve figured that out.
And then we realise we only know 5% of whats coming ln the test about the universe
When it comes to that humans know what they're doing, but when it comes to things that will cause economy to crash they have no idea what they're doing.
I just realized how gullible and sheeplike humans are. People have a history book, amongst other knowledge this book possesses, that contains information about how the Earth and the universe and life was created. But believe this book is factual is to believe that we have one all powerful God who is our authority, and his rules are what we should be following in order to ultimately receive his grace and blessings and eternal life. It seems to me that the only reason we reject the Lord and his words in the Bible is because we as humans want to be our own God, so as we don't want to follow somebody else's rules but ours. Why would we reject this history book from thousands and thousands of years ago only to believe wholeheartedly that we have as humans figured out everything to do with the creation of the universe and our world just within the past 150 years. Millions of people reject God and his authority because we don't want to listen to anybody else but ourselves
I'm totally blasted and fascinated of our knowledge how we can interpret things from universe. The knowledge leading us to not misinterpret the universe data. Fascinating! Thanks for your videos.
@Veritasium what if things like at 11:34 lead to something like kind of big-bang?
Very good video! I love learning about space everyday lets me know that theres something bigger and more crazy out there everyday
