I like to imagine Brian Cox isolatedly roams around deserts and derelict Brazilian prisons, offering impromptu astrophysics lessons and analogies.
hahaha funniest thing I heard all day. he's so genuinely nerdy compared to most other narrators.
So if you wanna learn astrophysics, but already have horrifyingly large student loans, just roam around deserts and brazilian prisons until you find him
Brian cox can derelict my balls
Cool guys don't look at explosions, they just turn an walk away.....
and they waddle away
To be fair, that was an implosion.
Personally would not have been able to do that scene lol
I just love that little fact that a star died so we could live. As Sagan said, that we are all star dust. Each time I think of that it humbles me, grounds me, brings me back to what really matters in this life.
A star doesn't die it's a lump of rock. Fools
MrShnazer Actually super-heated gas.
MrShnazer There's clearly a lump of rock between your ears, Mr Shnazer.
I feel the same, we're all in one great circle of life.
a life of emptiness.
i love how he puts the symbols of elements in a prison to teach us a lesson
Profesor Brian Cox is the coolest guy on earth.
I have nothing against Neil DeGrasse Tyson, but I would have loved to see Brian Cox in the remake of Cosmos instead; he explains things a lot closer to Carl Sagan.
yea this guy is closer to Carl Sagan than Neil, with a lot of respect
Britain vs America. With respect of course
it's 2023, now do you have anything against neil degrasse tyson? cuz the dude is off the rails completely
Brian is the guy Tyson wishes he could be. The envy must have been too much because Tyson is absolutely insane. The man is a complete tool.
Never has any Physicist looked more badass than Cox walking away from an explosion.
....pretty sure that the physicists involved in the creation of the Atomic bomb would say "Hold my Beer".....
He should've been wearing shades.
They were lying face down...not walking away..@@kimswhims8435
Those physicists were no where near the explosions they knew all about the dangers of what they were building unlike the soldiers who were near the bomb site.
What about about when he was bombin tags everywhere!
I saw this when I was barely 10, to the childhood me it was absolutely marvelous. It is a privilege to happen upon this source of inspiration.
5:52 Nailed it! Brian Cox should replace Daniel Craig in the next "Bond" film.
am i tripping shit or were these guys born one day apart
@@potatobob5781 You are absolutely right :-)
love this. Brian Cox is so lush :p We are born in the heart of a dying star.
Just like The Vindicators 3 episode in Rick and Morty, "You wish this was about sex! We loved eachother! We had a CHILD together! I conceived a child with a Million Ants and it died inside me because it was half a million ants and HALF COLLAPSING STAR!!!"
In short, smaller stars give out elements like C and O when they collapse under force their own gravity while bigger stars collapse at different phases and give out several heavy elements.
We live in a time of Professor Brian Cox . We can witness his knowledge and his understanding for science beyond any other scientist existed on Earth. Brian Cox gives me inspiration to study and research further science and get deeper into it. Thank you Professor for all your knowledge that you have shared with us.
That IS something, which means I can't criticise him too much
Imagine going to university lectures as a young student, listening to this genius human being explain and teach. I would have loved to study astronomy its so fascinating I cant take it!
I love some Cox in the evening :P
You wanna rephrase that sentence chief?
If any of you guys are looking for the music at the start. Its called 'Mini solar system by Sheridan tongue, Wonders of the universe. Hope it made your day!
2020 gang where we at?
Religion relies on metaphors to survive. It relies on people finding metaphors or believing that the scriptures are metaphorical. Thanks to science, the words have lost all literal meaning as we know (and have proven) it to be not true. Religion survives only by it's believers stretching the very fabric of their faith to fit or even cover the challenges and arguments brought to it by science. Religion is seeing the truth, knowing the truth and still living a lie.
Brian your such a great explainer, thanks man
I have seen this about 20 times never gets boring
I just witnessed vandelism
I read recently that in some the most advanced simulations of star death many of the simulated stars don't explode at all they simply collapse into their own stellar black hole thereby rendering the resulting black hole totally dark and alone. The very second I learned that this might be the case with many stars the whole idea about the universe being heavier that it looks like came into a new light, perhaps we are surrounded by invisible dead stars and not exotic dark matter. herpa derp?
Now we actually know who is the real Banksy!
We are all made of stars. We are all stars!!!
This series is amazing!
very clear and informative...
5:55 the nerd version of any Strong guy movie.. Cox in his elements!
5:55 like a boss.
OMG I know I listen to this on my Iphone. I can't watch him if I am tired only because he relaxes me and I fall asleep :(
Our city also has a bunch of rogue physicists running around painting graffiti everywhere, chemical symbols, equations ect. The whole city has went to hell.
UK gets Brian Cox while we get stuck with Neil Degrass Tyson as our science communicator. I hope you UK folks appreciate what you’ve got there!
Brian Cox brings new meaning to the expression, "Reach for the Stars"
People say ‘Reach for the Stars’
But
You know what the funny thing is?
WE are actually made from the Stars!
what is the song that is being played in the beginning? I've heard it before, but can't remember what it is called
Thanks
I'd like to know too. I don't think it was anything by D:Ream.
Mini Solar System by Sheridan Tongue
theres something soothing about this guy, even as he speaks of the end of all things lol
What is the music at the start?
5:55 prof. Brian cox acts like a movie star!!
5:55 Cool guys don't look at explosions......
Only 800 other people made this joke before you.
Song name?
Cool video lol 💥
Probably, the most unique and understandable scientist in the Universe.
I d like to know who plays the guitar on this episode at the beginning??
Beatlejuice beatlejuice beatlejuice
Does he have a vandalism license?
What did he vandalise?
4:45
Obviously
:-o...how can this guy have 45 years...has he found the blessing of immortality?
I’m the 3,000th like 🎉😮
vast... vast.... vast..... vast (its ok though brian, even though you repeat it lots you still sound so beautiful
I love you brother 🤗👏
@chessonmyshirt
He was using the spray paint to mark each layer of the building to represent each layer of a stars core. He started with the outermost layer which was made up of Hydrogen and kept going through each shell (each floor of the building towards the bottom) in order until he reached the inner most layer (the bottom floor) where iron is made. After that all that was left was for the star (prison building) to implode.
I agree with you
People say "god" made the world, so who made god?
then who made the person who made god?
then who made the person that made made the person that made god?
then who made the person that made the person that made the person that made god?
I want to be an atheist but after accedently coming across Satan vids (because im doing an rs project) I feel scared about not believing at the same time.
Religion isn't even worth the effort to deny. Just know that you are right and much better off without it. Let idiots be idiots.
What a show in this video! Thanks professor!!
You do realise that the seven days if creation is a metaphor that people used back then because they didnt have the scientific evidence to know what we know now. Please dont dismiss a religion because you assume everything is literal
@Lionanwar1979 ok, lets say god did create everything like in the creation story who exactly recorded this? i not saying you're wrong but we have to use evidence as we werent there ourselves.
LOVE LOVE LOVE THIS!
Stellar nucleosynthesis by super nova is only capable of creating elements up to and including Zirconium, the heavier elements found within the debris of the exploding star are the result of an much earlier process which took place within a black hole.
Mathematical simulation and modelling has shown that these heavier elements which require enormous forces to be created can only be formed beyond the event horizon of a Black Hole.
The enormous pressures within the gravitational field of a black hole are not only capable of creating heavier elements but they act as a containment for atomic reactions.
The only way the matter containing these elements can escape the black hole is a localised gravitational reversal. It is thought that the reversal is the result the sheer quantity of matter contained within the black hole and the ensuing gravitational instability.
When a gravitational reversal occurs, within the black hole, the balance of kinetic and potential energy are restored to the atom, allowing the element to expand. This barely sub light speed expansion allows the matter to “explode” beyond the event horizon.
The modelling indicates that 250 million metres second (84%) is probable.
When sufficient matter has been discharged from the black hole the Universal gravitational polarity will return to the black hole. Then Black Hole will then continue to capture material within its gravitational field.
Those elements which were discharged with sufficient velocity and are now beyond the effects of the event horizon, will eventually be captured by stars.
The stare may have already gone into supernova, but the light hasn’t reached us yet.. 👀
@skyguy1968 We'll make sure "true beleivers" dont get to escape on our spaceships, then the sun will roast them when it finally gives out!
That is some seriously cool graffiti.
@lionanwar1979 most of this stuff has been proven but just because you dont believe it doesnt mean you have to rant about. :-)
You can't leave it there. What happens next? After the explosion, how does the Carbon and Oxygen and all the other elements get out to make it to Earth to become us? How do they avoid joining the black-hole?
Amazing documentary if you have the chance to watch the entire thing.
We watched this in physics class
Brian cox is god.
@mmmmmwwwwwjjjjj dude, that is brilliant! and couldnt be more correct
5:55 reminded me of the "Cool guys don't looks at explosions" video.
that demolition was a badass conclusion
@smexijebus Religion has been around longer. Just not any modern religions.
If the heaviest elements (what are they I don't know) were created at the last stage of dying stars, doesn't that mean the heavier the element is the more rarely it can be found? If humans can replicate the process of fusion, can we create gold out of some cheaper elements?
Also, in this documentary, Brian Cox said there is only 92 elements in the universe, then how come there is 118 elements on the periodic table? If all elements are just the dust of dying stars, then how come we can create new elements in laboratories?
Can someone PLEASE help me with these questions? Thank you.
There are only 92 naturally occuring elements. The others you mention are synthetically produced.
Fusion is in the sun is the fusion of Hydrogen atoms to form helium atoms. So we'd only really produce helium (and some tritium) in a fusion reactor. The other heavier elements are produced in the run up to a supernova when the star collapses in on itself. Those are conditions we will never replicate.
mikeymoo1992 Yes, and that's why I am confused.
What do you mean by "synthetically produced"? Are they like alloy or something that is created by combining different natural elements? Are they marked differently on the periodic table? What is the heaviest elements (the last ones being created during the collapse of supernova)
Is there some commonly used synthetic elements?
These facts really amaze me, but I'm like an idiot when it comes to physics.
synthetically produced elements are made by firing smaller and lighter elements together in an atom smashing device like a syncrotron. Only a few atoms of such 'synthetic elements' can be produced at any one time (not enough to make any tangible material) and they break down almost instantaneously. These elements only exist for a fraction of a fraction of a fraction of a second as they so unstable. The heaviest element produced in a supernova is Uranium (No. 92)
Technetium is technically synthetic as there are no stable isotopes on earth but can be a product of nuclear fission. It gets used as a tracer for certain medical applications.
mikeymoo1992 Thank you for helping me, thank you very much :)
My pleasure, hope you understand it now!
Humans can’t even decide how many genders there are and here we are claiming to understand some cosmic phenomenon. LOL
No mate, we dismiss religion because it's complete and utter bollocks.
So then how do the elements survive the implosion?
How do they survive those temperatures at all?
that in the bible therefore it must have been created by satan... haha
All the elements come from stars?!?!?!
***** Thanks man... This shit is crazy. btw I'm 15 also you must be a fucking genius!
***** pretty cool that you are 15 and interested in physics/astronomy/cosmology. I'm 24 and i just recently became infatuated with our physical universe and the way it works (wish I would have realized my love for science at your age).
I took my first astronomy class this semester in college and learned a lot of amazing stuff like what Prof. Cox discusses in this video. Im really thinking about pursuing a degree in astrophysics after I get my bachelors in engineering.
If you love it, go for it kid! Dont let anyone convince you otherwise.
and there is nothing wrong with being a nerd lol
Awesome! Good luck with that man.
Max O Which means the atoms that made up your body came from super massive stars that died out billion years ago. You are made of stardust. How cool is that?
Anh Trieu that's fucking scary yet extremely fascinating
Aragh Brian Cox is so hot. Am I the only one who thinks so?? haha
Brian should’ve been planting high explosives as he descended lol
5:55 "Cool guys dont look at explosions"
Brilliant.💖
OMGGG I can't believe I was made of dying star
We shouldn't worship gods, if anything, we should worship things that genuinely provide for us before we can understand God. Things like the planet, the moon, our Sun, our Galaxy.
kkkkkkk, Fábio Bruno Contruções Ltda.
The building represented the star, and he was using the spray paint to write the elements created during the star's collapse and final implosion (represented by the bang at 5:49). So he was spraying because it didn't matter that he was defacing a condemed buiding that was about to be demolished. He could have pissed up the walls, for all it mattered, but writing stuff like Fe is hard, cos when you finish F you have to stop and then start again, with a curlicar e, and might piss on your shoes :)
Science involves formulating a hypothesis based on observation, and then testing that hypothesis to see if it holds true.
Religion is filling in all the parts of the world we don't understand with god. Religion is not poor science, it is the absence of it.
@dreadscythe92
the one thing i dont get is how does science explain somthing coming from nothing in the first place when nothing had higher entropy.
i believe in the big bounce theory but he seems to be saying that it all just happens once.
i saw another scientist saying it can change again if something outside of the thing with really high entropy interfears with it like a person can make a low entropy sand castle out of a high entropy pile of sand thus braking the rule.
So in effect what your saying is because we don't know something we need too put god in somewhere too fill the gap. That only makes more question and ones less likely too answer. IF god made everything what created god? That's why religion is flawed. It stops trying too solve problems and says "well god did it".
Science has no agenda, apart from us as people learning more too improve our lives.
All religion has a agenda too control our thoughts and actions.
@Koloszrodosthe I believe religion has been around long before science. I'm completely against religious ideology, but logically, it's had to have been around longer. Back before we were able to examine our world, and the natural phenomenon that occurred around us, it would have been easy, even rational, especially comforting, to assume deities controlled our world. With our exponential growth in knowledge, we now know much more than we did previously, and we will continue to discover.
We were speaking in context of our existence as a species. Thus why I used the words 'our world'.
Even we were not speaking in context, it would still be correct. We simply stated that religion existed before science. If these other species existed, the same would be held true.
It boils down to the fact that ignorance always precedes knowledge.
So I’m actually Mjolnir? Sweet….
OMG! Oddlog, your comment is as bad as the one it's replying to!
Religion and science can both be beautiful and terrible. At least keep an open and honest mind on that one.
* as opposed to Prof Brian Cox who's just beautiful ;)
@HealthyCabbie Professor Cox is a particle physicist, a Royal Society University Research Fellow and professor at the University of Manchester. There is no way he is going to risk his standing and his livelihood in the scientific community based simply on "guess work".
Bleak?!?
Personally I feel lucky as I don't know what.
I beat the odds. I made it into life. I now have the immense privilege of being the custodian of these atoms and not only that but I can observe and investigate the surrounding universe, and it leaves me awestruck.
I'd say that is a grand way to look at the universe, not bleak.
I watch this to go to sleep
Brian has such a hypnotizing voice
^_^
Lol in 2021 i comment
Science class..... but make it EDGY
In this episode of Wonders of the Universe, Stardust, he plays part of a song on a piano in this wooden cabin. Does anyone know what he was playing? I have been searching the internet for ages and I haven't found an answer. Someone please help!
Didn’t see that coming
If every bit of matter in the universe cam together it would become a black hole. THAT is what exploded. That was the beginning.
I was asked a question the other day that i cannot answer. If the big bang was a star exploding, How big was that star? Has anyone ever worked it out?
The sun is worth more than all the gold on earth
…..how hot does it have to be to not allow atoms to form?
He may be a great scientist but he's no Banksy with a spray can!
Where is this place? I think it is Brazil, I saw some portuguese words at 3:51 at the abandoned ruins
@HealthyCabbie It isn't speculation, the basic principle is being used right now to create fusion power, creating conditions so hot and pressurized that it fuses hydrogen atoms together.
Plz upload the other part where he talks about elements higher than iron
