Thank you Brian, for inspiring a 16 year old kid to pursue physics. I’m 22 now and 1 year away from my bachelor’s degree in physics. I would not change it for the world. “To fall in love with physics is to fall in love with the universe”.
Congratulations, I was on your path at one time- don't let anything distract you, I did- now it's 36 years later and I just never got back to finishing school. Let it slip away; there was always something more pressing and I didn't have the discipline to work and go to school. I worked a labor job, hot and heavy work- and had no time to even shower or change before running to class. By the time I got home at night I was exhausted, I had no energy left for my studies. Then I met a girl... and I'm sure you've heard the story before, it's common. I would give anything to go back and do it differently, but this isn't a Disney movie. But hey- you're doing it man, hang in there, you may have a verse to contribute that we can't afford to lose. Hopefully the present admin gets out of the way eventually and science gets back to normal here, kind of a nightmare right now.
@ thank you for this comment sir! I’m glad to see that you’re still interested and enjoying physics. I hope that you still are happy despite maybe having some regrets about how it all played out. I really took your comment to heart and your support is extremely meaningful! I understand exactly what you mean, I have to work 2 jobs to put myself through school and it can get extremely difficult sometimes to push onward but I just remind myself of the love and joy that got me into the subject in the first place. I will be documenting my journey on my RUclips channel if you’d like to watch. Later this week I will be posting a video about some research I am currently involved in this summer with my professor. Thank you again for the kind words, cheers!

Brian Cox is the Carl Sagan of my generation. I’ve grown up to see him in videos, on tv, YT, & everywhere. His demeanor, his permanent smile, his soft articulate voice, & the feeling that translates across from him of pure passion, love of, respect for the physical known & unknowns around us as well as his genuine love for educating other beings about those most mind blowing, unfathomable & incomprehensible traits of the physical universe. Brian is nearing 60 years old & still looks like a college undergrad. Thank you Brian for all these years of explaining all that is impossible to wrap my mind around, into videos & lessons that bring a bit of perception to the imperceptible.
Are there perception and reason methodology grounds for claiming -35 is a number when imaginary number = √-1 but -1 . -1 = 1 = 1 . 1 = √1 , for square root √x the length of the straight line side of a square with area x of base multiplied by height and " . " multiplication?
I love being a speck on a speck on a speck in the universe. Because that means to me that I am equal to every other speck, with equal presence and equal importance. It means that I and all the other specks are equally woven into the fabric of space time. On the tiniest of scales, I am just like everything else and I am an equal part of the whole. I find that so incredibly comforting.

As someone who has suffered with mental illness and depression the majority of my adult life. I just tried DMT for the first time, I felt as if I was in the center of the universe, what an awesome experience.

My sweetest memory of Brian is when he practically showd regardless of weight of an object they fall together subject to a vacume Stat. I still love how beautiful that moment was
Brian is one of the best in explaining the unexplainable! I thought I had an idea of what a Plancks length was, but I was way off and this just got me staying up late thinking about it. I belonged to an astronomy club that went to schools after hours to meet with students and introduce them to our telescopes. We had one we called Godzilla that we towed behind a car. Made my 8 inch Smitt-Cassigrain look puney. I would get bored of saying "Look but don't touch!" Over and over to kids that expected to be wowed like in a video game. Then one night this 8yr old girl looked at Saturn through my scope and my life brightened. She giggled and wouldn't stop looking and called her dad over and just couldn't get over it. I've oftened wondered if that night mat have changed her life.
Whilst I am far from stupid, I am, however, woefully uneducated and find anyone that is a master of any subject, an absolute pleasure to listen to. I won't pretend to understand everything that Brian said, but because I find both him and the subject matter so interesting, it motivates me to learn more. The inate ability to hold someone's attention no matter the subject is a skill that very few have.
He engages with his listeners so well. The smile on his face, the hand action, and explaining everything in simple layman terms. Wish I had studied quantum physics. My favorite subject. Quantum physics and many eastern philosophies aligns beautifully.

I'm 21 Years old currently. I was always bad with math and science in school, so I didn't pass those subjects. Now I'm in love with it (Thanks to Brian Cox), I'm planning on redoing my High School certificate to one day hopefully study Physics in university.
To all of you who are here seeking even a fragment of the truth the universe hides from us-I feel it is my duty to tell you that a book called Astrological Deception opened my eyes. My perspective has expanded beyond this world… even into other dimensions.
I’m genuinely surprised to see someone else who’s heard of that book-and of the author, Azarus Kain. His works are a treasure the elite would rather we never discover. I’m not even sure if it’s still available online anymore. :(
Brian Cox is a universal Legend, dare I say. I really admire how he can take a subject as breathtakingly stupendous in scale and bring it to us on a scale, that mesmerizes us all. I wish he was my science teacher back in the day.
I Love Brian Cox no ego or narcissism thinking he is better than everyone like others cough *Neil*. Just pure love for science and sharing that love with others. It's always a pleasure listening to him speak.
I can make it about 5 minutes into a Brian Cox lecture before my stupid brain just starts going "lal lalal lal lalla..." and after that I'm just hypnotized by the sound of his brilliant brain.
It probably took me a solid 20+ minutes to get through the whole video. The thought drift was strong with this one😂 Amazing video. After rewatching segments a couple times the concepts and interpretations of scale really started making sense.
I’ve heard life was a gift, a gift to the universe where we could learn to understand the facts about it….hence us not being so insignificant. I may be talking rubbish though and just dreamt it. 😂😂😂
Mind completely blown again thinking about the planck length, even had to stop the video to read up on it some more! Reminds me of the Attosecond! Which also completely blows my mind as there are more attoseconds in a single second of time, then there have been seconds in the entire time line of the history of the Universe since the Big Bang! And this occurs each and every second that goes by. The 2023 Nobel Prize in Physics was awarded to Pierre Agostini, Anne L'Huillier, and Ferenc Krausz for their experimental methods generating attosecond pulses of light, unbelievable!!!
It really is mind boggling! I just googled 'Planck time vs attosecond.' _"Planck time is far smaller than an attosecond; a second is much closer to the age of the universe than Planck time is to a second."_
I don't think of it as something "occurring", just a unit of measurement, e.g. a way we slice up the Universe into a category. As we do everything. But in a way this is one continuous process.
A light year is so far that most humans can’t conceive how far based on experience. Voyager 1 launched 48 years ago and yet has only travelled roughly 1/380th of a light year even though it is traveling at a speed of around 60k+ km/h. At that speed it will take over 15000 years to reach a single light year of distance. The closest star to the sun is over 4 light years away.
Brian Cox is amazing in my eyes as he went from being a pop star to being a world famous physicist and thats incredible. He inspired me to go study physics and astronomy which are subjects I've always loved and still do, so thank you Brian.
The Planck length had never been defined to me before. Really interesting! I understood that it was the smallest possible size we could probe, but never understood the why. Thanks Brian!
Oh man... this guy is a genius. Not only is he speaking slower for us to absorb the information better but he also gives a visual of size with the video going in and out of shot to show u size in measurement. GENIUS! Best educator about this topic by far!! ❤ Thanx Brian.
@@startledmilk6670 calling him Sir wouldn't sound rude. It would sound a bit silly, like you were trying to kiss his arse, a bit awkward maybe, but not rude.
I don't normally talk about this publically because it's difficult, but this topic actually makes me incredibly sad. So sad, it can nearly give me a panic attack at night if I let it. These scales and the times involved, I.E. billions of years, makes my life and mortality in general feel overwhelming. It's emotionally difficult for me to imagine being dead and that state existing well forever. On one hand it's beautiful to think about the universe in these terms, but it can be overwhelming for me
What a staggering concept. That we could feasibly be living on a globule that's at the bottom of someone else's pond. But to us, that pond is the universe.
I feel so small watching this, I feel smaller knowing how short our life is compared to time and travel, Brian Cox is such an amazing educator, love his teachings.
Beautiful video. Reminds me of the quote from the one and only Hitchhiker's Guide to the Galaxy: “Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.”
A humble, intelligent, and inspiring science communicator. His curiosity and positivity shine through-watching him talk about the universe is always a joy.
There's an estimated 200 billion stars just in our own galaxy. It's impossible to comprehend the size of that number. If you spent one second looking at each star in our galaxy, you'd have to spend the equivalent of all of humanity's recorded history to look at all of them. Do the math yourself if you don't believe me. It would take six - thousand - years. Without breaks or sleep.
While I thought it would be Neal, Brian has become our new Segan. His absolute amazement and humility in the face of what we don't yet know, even as he knows more about what we do than most
We are an inextricable part of the Universe. As conscious beings, we are the Universe observing itself. The feeling we have of being, in any way, 'separate from' the Universe is simultaneously very real and yet ultimately an illusion.
I begin to get a sinking feeling whenever I think of the sheer size of things in space. Picturing myself in front of something like the black hole in Interstellar or even orbiting Jupiter are a couple of examples.
I get the same sinking feeling and I have a huge feeling of anxiety and dread when I think about the scale of the universe and how much we will miss, our life is gone in a blink of an eye on the cosmic scale.
if u think a little further, we do make an impact no matter how small, but its as real as the existence of this universe.. we are essentially a part of all of this cosmic playground, no matter how small, but a real part as the sun.. just an idea evoked from that comment so i shared.. and if u think about it this one comment and this one video was an abstract non existing idea in someone's mind and now its a thread of atleast 2 comments
@@aman_design we do not matter in x years all we have accomplished is gone... you and me will be long gone everything we did is forgotten everything humans did is obliterated because the sun will keep expanding all is for naught
It is beautiful to think that, despite how miniscule we are. We get to grasp how massive universe is! Thanks to all keen scientists, lecturers, educators and many more!
It’s incredible how Brian’s explanations bring a calming perspective to the way the universe works. I’m not a scientist, but the understanding he brings on a conceptual level is fascinating.
“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's long way down the road to the chemist's, but that's just peanuts to space.” ~Douglas Adams, HHGG
The universe is big. That's an understatement. As you said, we think of scale in our own environment. Long distances might be thought of as distance between two points in an airplane. A flight of two hours might get you between Los Angeles and Seattle. A flight to the nearest star would take tens of thousands of years. To a person, a million, a billion, a trillion, might be thought of as the same. It's just a big number. We just can't really think what a trillion galaxies are, each with billions of stars. Incomprehensible, but that is what we live in.
Einstein repeatedly said that singularities are not possible. His reasoning explains dark matter. He wrote in 1939 - "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (he was the first to claim Relativity predicts singularities) do not exist in physical reality. Although the theory given here treats only clusters (star) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light" He was referring to Relativistic dilation. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light" This doesn't mean mass increases, it means mass becomes spread throughout spacetime relative to an outside observer. Even mass that exists at 75% light speed is partially dilated. Time dilation is just one aspect of the phenomenon. It occurs wherever there is an astronomical quantity of mass. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers. Our galactic center is dilated. ThIs means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is spread throughout spacetime. In other words that mass is all around us. It's the "missing mass" needed to explain galaxy rotation curves. 99.8% of the mass in our solar system is in the sun. 99.9% of the mass in an atom is in the nucleus. This indicates 100's of trillions of solar masses in the centers of common spiral galaxies. Gravitational forces in our galactic center would be astronomically higher if it wasn't for dilation. It doesn't occur in galaxies with low mass centers. They don't have enough mass to achieve relativistic velocities. It has been confirmed in 25 dwarf and ultra diffuse galaxies to have normal rotation rates.
It's borderline depressing to think just how unfathomably massive the universe is and the tinniest of specs we are, in the grand scheme of things, we are infinitely less than utterly insignificant.
Brian Cox is to physics education as Attenborough was to the world of nature. Both inspire wonder and spark great curiosity. What an amazing time we live in. 👍🏼
Well, it's certainly true that we are a _very, very_ small subset of the universe contemplating a _very, very_ small subset of the universe, during one _very, very_ small moment of time in the universe's life thus far... I suppose... though you could doubtless throw a few more "very's" in there if you wanted to be more exact... you know - _very, very, very_ small...
@@simesaid The cosmologists tell us that the universe is infinite, as asserted in this video. If this is correct, then we are an integral part of that infinity, which makes us infinite too. In this broader sense the concepts of time, size and subset lose most, if not all, of their meaning. Finally, as far as know right now, we are the ONLY part of the universe that is capable of this kind of reflection. This makes our utter disregard for the place that has nurtured us in to awareness just that much more insane and reckless.
Professor Brian never ceases to expand my mind and communicate a sense of wondrous awe and joy, even as we contemplate immensity. Subscribing to see the full interview!
Please stop using inches and miles in science videos. Everyone blames America for imperial units not being retired, but the real blame should go to those who pander to Americans.
@@Safetytrousers Using two separate measuring scales at the same time reduces everyone's understanding and intuition. Dual units harm British workers' numeracy and hurt the country's industrial competitiveness.
@@DemPilafian That doesn't change the fact I only understand human heights in feet and inches and long distances in miles. For personal measurements I do only use metres and centimeters, but for some reason I have a blind spot for human height in those units.
A few months ago I hit rock bottom mentally. I was overwhelmed, broke, and just tired of pretending I had it all together. Someone in a podcast mentioned Manifest and Receive by Eva Hartley and I figured, why not? That book didn't just help me dream again - it showed me how to anchor those dreams in reality. Now, I’ve manifested opportunities I never imagined possible, and my mindset has shifted completely. If you’re frustrated like I was, don’t hesitate. Read this book. It will change everything ❤
The idea presented by David that life can be flourishing at larger distances and objects/planets if human being becomes that much more capable and intelligent is true in a probabilistic way with probability seeming dim in ratio. Great video, nicely explained as always!
Brian, this is a beautiful and insanely thoughtful way in explaining the universe. This really evokes my curiosity in learning deeply in astronomy and everything
I love these sorts of talks, and Dr Cox does a masterful job of illustrating this topic. He describes the distance from Earth to the CMB as 46B LY around the 9:30 mark, then says the "radius" of the observable universe is 92B LY. I believe he meant the diameter, if I might meekly correct him from my humble armchair.
I all respect to the attempt made here, i want to humbly say that, the youtube channel Epic spaceman, does the job of explaining the scales of universe much much better.
i wonder how such smart individuals like him tend to deal with a feeling of existentialism or existential crises. how does one not lose their mind thinking about existence?
Thumbs-up this comment if we should release Brian’s full interview this Friday!

Brian is so cool in the way he explains things. He tells you the data, the numbers and the science, but also in a way that's inspiring.
We will never know everything about everything, let alone the overall scale of our universe. A humbling idea.
I'm 21 Years old currently. I was always bad with math and science in school, so I didn't pass those subjects. Now I'm in love with it (Thanks to Brian Cox), I'm planning on redoing my High School certificate to one day hopefully study Physics in university.
"Or you could just call me Brian."
Brilliant. What a fantastic bloke.
I could listen to Brian Cox talk all day long
So thankful for Brian Cox. It never gets old to hear from him. Such a great communicator and human being.
Get a room.
Brian Cox is without doubt one of the universe's greatest gifts to mankind. We are very lucky indeed.
Brian being Brian ❤
Just doin' what he do!
To all of you who are here seeking even a fragment of the truth the universe hides from us-I feel it is my duty to tell you that a book called Astrological Deception opened my eyes. My perspective has expanded beyond this world… even into other dimensions.
I’m genuinely surprised to see someone else who’s heard of that book-and of the author, Azarus Kain. His works are a treasure the elite would rather we never discover. I’m not even sure if it’s still available online anymore. :(
Where i can find it, typed the name of the book into my browser and couldn't find anything?
What is book about?
I finally found it, I thought it was a scam but I successfully bought it and I hope the book will not disappoint me 😅
I don't understand, is the subject of that book at all related to the subject of this video?
Brian Cox is a universal Legend, dare I say. I really admire how he can take a subject as breathtakingly stupendous in scale and bring it to us on a scale, that mesmerizes us all. I wish he was my science teacher back in the day.
These are some pure golden nuggets of wisdom that will take a lifetime to fully digest
Thank You Brian
I Love Brian Cox no ego or narcissism thinking he is better than everyone like others cough *Neil*. Just pure love for science and sharing that love with others. It's always a pleasure listening to him speak.
You're just a dude at Walmart. You're not the expert.
Neil doesn't have an ego.
He just knows what he's talking about in a country full of idiots.
LdeGrasse Tyson is just the worst. Absolute cringe lord.
Tyson is one of those whose political leanings have comprised his scientific objectivity.
@gordons2439 He's definitely not.
Bedankt
I can make it about 5 minutes into a Brian Cox lecture before my stupid brain just starts going "lal lalal lal lalla..." and after that I'm just hypnotized by the sound of his brilliant brain.
It probably took me a solid 20+ minutes to get through the whole video. The thought drift was strong with this one😂
Amazing video. After rewatching segments a couple times the concepts and interpretations of scale really started making sense.
I’ve heard life was a gift, a gift to the universe where we could learn to understand the facts about it….hence us not being so insignificant. I may be talking rubbish though and just dreamt it. 😂😂😂
You may well be a halfwit.
Thank god for Planck's length. I feel very nicely endowed now.
I could watch briax cox videos all day and night he's a great narrator and full to the brim of knowledge
Absolutely mindblowing, but reasonable
Mind completely blown again thinking about the planck length, even had to stop the video to read up on it some more! Reminds me of the Attosecond! Which also completely blows my mind as there are more attoseconds in a single second of time, then there have been seconds in the entire time line of the history of the Universe since the Big Bang! And this occurs each and every second that goes by. The 2023 Nobel Prize in Physics was awarded to Pierre Agostini, Anne L'Huillier, and Ferenc Krausz for their experimental methods generating attosecond pulses of light, unbelievable!!!
Okay now that I've recovered maybe I can continue the video!
There is also the planck time ;)
It really is mind boggling!
I just googled 'Planck time vs attosecond.'
_"Planck time is far smaller than an attosecond; a second is much closer to the age of the universe than Planck time is to a second."_
I don't think of it as something "occurring", just a unit of measurement, e.g. a way we slice up the Universe into a category. As we do everything. But in a way this is one continuous process.
Atosecond light pulses...? My mind can't make sense of how something like that could even be a consideration to replicate by human beings...
Brian Cox videos should be shown in every school room he is a wonderful educator.
Damn shame there's no room for science in the curriculum anymore, unless it's the lobotomized 'scientific creation' nonsense...
A light year is so far that most humans can’t conceive how far based on experience. Voyager 1 launched 48 years ago and yet has only travelled roughly 1/380th of a light year even though it is traveling at a speed of around 60k+ km/h. At that speed it will take over 15000 years to reach a single light year of distance. The closest star to the sun is over 4 light years away.
Brian Cox is amazing in my eyes as he went from being a pop star to being a world famous physicist and thats incredible. He inspired me to go study physics and astronomy which are subjects I've always loved and still do, so thank you Brian.
The Planck length had never been defined to me before. Really interesting! I understood that it was the smallest possible size we could probe, but never understood the why. Thanks Brian!
Oh man... this guy is a genius. Not only is he speaking slower for us to absorb the information better but he also gives a visual of size with the video going in and out of shot to show u size in measurement. GENIUS! Best educator about this topic by far!! ❤ Thanx Brian.
I will call you Professor Brian Cox with all due respect if it was up to me I would call you Sir Brian Cox ❤
It’s rude to call someone something they didn’t ask you to call them.
@@startledmilk6670 calling him Sir wouldn't sound rude. It would sound a bit silly, like you were trying to kiss his arse, a bit awkward maybe, but not rude.
@ when someone says, “call me Brian” you don’t then call them something they explicitly to not call them.
I don't normally talk about this publically because it's difficult, but this topic actually makes me incredibly sad. So sad, it can nearly give me a panic attack at night if I let it. These scales and the times involved, I.E. billions of years, makes my life and mortality in general feel overwhelming. It's emotionally difficult for me to imagine being dead and that state existing well forever. On one hand it's beautiful to think about the universe in these terms, but it can be overwhelming for me
Spellbinding Presentation،
Thank you all۔
I never tire of this man's ability to communicate complex principles and phenomena on an introductory level. My thanks to you, Brian.
What a staggering concept. That we could feasibly be living on a globule that's at the bottom of someone else's pond. But to us, that pond is the universe.
And that’s just what our brain comprehend.
I feel so small watching this, I feel smaller knowing how short our life is compared to time and travel, Brian Cox is such an amazing educator, love his teachings.
Excellent presentation Brian. Slight error at 3:20 though with Plancks constant. It is 34 zeros one, not 35 😉
Beautiful video. Reminds me of the quote from the one and only Hitchhiker's Guide to the Galaxy: “Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's a long way down the road to the chemist's, but that's just peanuts to space.”
A humble, intelligent, and inspiring science communicator. His curiosity and positivity shine through-watching him talk about the universe is always a joy.
Brian Cox is such a great science communicator - the best one out there.
There's an estimated 200 billion stars just in our own galaxy. It's impossible to comprehend the size of that number. If you spent one second looking at each star in our galaxy, you'd have to spend the equivalent of all of humanity's recorded history to look at all of them. Do the math yourself if you don't believe me. It would take six - thousand - years. Without breaks or sleep.
What a great comment, thank you!
There are more trees on earth than stars in the milky way
@simondaviesphoto no there's not. There are more stars in The Milky Way Galaxy than there are grains of sand on Earth.
@@simondaviesphotoI got it wrong. 👍
Most people don't even know how big our own star (the sun) is
“It is the light in your eyes that can be measured Brian when you look for light and find it beautiful”
❤️
While I thought it would be Neal, Brian has become our new Segan. His absolute amazement and humility in the face of what we don't yet know, even as he knows more about what we do than most
Get a room
Every now and then when I think about size of the universe or talk about it, I began to feel some kind of anxiety.
We are an inextricable part of the Universe. As conscious beings, we are the Universe observing itself. The feeling we have of being, in any way, 'separate from' the Universe is simultaneously very real and yet ultimately an illusion.
I begin to get a sinking feeling whenever I think of the sheer size of things in space. Picturing myself in front of something like the black hole in Interstellar or even orbiting Jupiter are a couple of examples.
I get the same sinking feeling and I have a huge feeling of anxiety and dread when I think about the scale of the universe and how much we will miss, our life is gone in a blink of an eye on the cosmic scale.
Aren’t we a little late to be the universe observing itself? What was observing the universe in the 13.8 billion years before we came along?
I'm the opposite, I like to think about the size of the universe to reduce anxiety.
finally I hear someone say it. Every measurement is from our human perspective!
10:20 "we don't matter at all" 🙌
if u think a little further, we do make an impact no matter how small, but its as real as the existence of this universe.. we are essentially a part of all of this cosmic playground, no matter how small, but a real part as the sun.. just an idea evoked from that comment so i shared.. and if u think about it this one comment and this one video was an abstract non existing idea in someone's mind and now its a thread of atleast 2 comments
@@aman_design we do not matter
in x years all we have accomplished is gone...
you and me will be long gone
everything we did is forgotten
everything humans did is obliterated because the sun will keep expanding
all is for naught
How liberating is that? The Absolute is endlessly playing this game. Mattering, not mattering. Consciousnessing, not consciousnessing.
“Mattering,” is an inconceivable concept for our minds to truly grasp. The more we accept our unimaginable ignorance, the closer we get to reality.
It is beautiful to think that, despite how miniscule we are. We get to grasp how massive universe is! Thanks to all keen scientists, lecturers, educators and many more!
I love you Brian
It’s incredible how Brian’s explanations bring a calming perspective to the way the universe works. I’m not a scientist, but the understanding he brings on a conceptual level is fascinating.
“Space is big. You just won't believe how vastly, hugely, mind-bogglingly big it is. I mean, you may think it's long way down the road to the chemist's, but that's just peanuts to space.”
~Douglas Adams, HHGG
The universe is big. That's an understatement. As you said, we think of scale in our own environment. Long distances might be thought of as distance between two points in an airplane. A flight of two hours might get you between Los Angeles and Seattle. A flight to the nearest star would take tens of thousands of years. To a person, a million, a billion, a trillion, might be thought of as the same. It's just a big number. We just can't really think what a trillion galaxies are, each with billions of stars. Incomprehensible, but that is what we live in.
Einstein repeatedly said that singularities are not possible. His reasoning explains dark matter. He wrote in 1939 -
"The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (he was the first to claim Relativity predicts singularities) do not exist in physical reality. Although the theory given here treats only clusters (star) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light"
He was referring to Relativistic dilation. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light" This doesn't mean mass increases, it means mass becomes spread throughout spacetime relative to an outside observer. Even mass that exists at 75% light speed is partially dilated. Time dilation is just one aspect of the phenomenon.
It occurs wherever there is an astronomical quantity of mass. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers.
Our galactic center is dilated. ThIs means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is spread throughout spacetime. In other words that mass is all around us. It's the "missing mass" needed to explain galaxy rotation curves.
99.8% of the mass in our solar system is in the sun. 99.9% of the mass in an atom is in the nucleus. This indicates 100's of trillions of solar masses in the centers of common spiral galaxies. Gravitational forces in our galactic center would be astronomically higher if it wasn't for dilation.
It doesn't occur in galaxies with low mass centers. They don't have enough mass to achieve relativistic velocities. It has been confirmed in 25 dwarf and ultra diffuse galaxies to have normal rotation rates.
Im getting chills everytime I listen to Brian speak
It's borderline depressing to think just how unfathomably massive the universe is and the tinniest of specs we are, in the grand scheme of things, we are infinitely less than utterly insignificant.
And yet we all march around like we are individually so important to the universe lol
Or it’s simply incredible we exist as we are in the universe we’re in.
This is where philosophy helps.
Not all that insignificant listening to the end on what our potential is.
Brian Cox is to physics education as Attenborough was to the world of nature. Both inspire wonder and spark great curiosity. What an amazing time we live in. 👍🏼
We are the universe contemplating itself. That's not theology or philosophy . . . it's truth.
Well, it's certainly true that we are a _very, very_ small subset of the universe contemplating a _very, very_ small subset of the universe, during one _very, very_ small moment of time in the universe's life thus far... I suppose... though you could doubtless throw a few more "very's" in there if you wanted to be more exact... you know - _very, very, very_ small...
@@simesaid The cosmologists tell us that the universe is infinite, as asserted in this video. If this is correct, then we are an integral part of that infinity, which makes us infinite too. In this broader sense the concepts of time, size and subset lose most, if not all, of their meaning. Finally, as far as know right now, we are the ONLY part of the universe that is capable of this kind of reflection. This makes our utter disregard for the place that has nurtured us in to awareness just that much more insane and reckless.
Save the universe will cease and we will not.
@@bogusphone8000 It hasn't yet . But countless of us have .
I often get lost in my own issues, but this brings you back. great vid.
You touched me, now i need a universe to explain how it feels
Sounds poetic to me lol..maybe thata a good song lyric? What made youbsay that if I may ask?
what do dis mean
@@leif1075 Brian
I firmly believe that if we free our minds of all previous beliefs, we will go beyond what's believed.
Fabulous, fantastic & fruity....
Professor Brian never ceases to expand my mind and communicate a sense of wondrous awe and joy, even as we contemplate immensity. Subscribing to see the full interview!
The universe means nothing to 99.9999999999999999999% of people.
I'm bewildered by how much Brian remembers!
Please stop using inches and miles in science videos. Everyone blames America for imperial units not being retired, but the real blame should go to those who pander to Americans.
Metric system rules.
Speaking as a Canadian - I whole heartedly agree..
In the UK we still think of people's heights in feet and inches and distance in miles. And that is how I can only understand those scales.
@@Safetytrousers Using two separate measuring scales at the same time reduces everyone's understanding and intuition. Dual units harm British workers' numeracy and hurt the country's industrial competitiveness.
@@DemPilafian That doesn't change the fact I only understand human heights in feet and inches and long distances in miles. For personal measurements I do only use metres and centimeters, but for some reason I have a blind spot for human height in those units.
Put this video away for 1000 years and and it will still hold up. Beautiful video
Nothing is a coincidence.
It’s always fascinating to listen to Brian speak. Makes learning about the cosmos and physics intriguing!!
Reminds me of our wonderful Creator. *John 14:6.*
Demonstrate the existence of a creator...
So some iron age jewish deity created a 13.8 billion year old universe from nothing,in one day?
A few months ago I hit rock bottom mentally. I was overwhelmed, broke, and just tired of pretending I had it all together. Someone in a podcast mentioned Manifest and Receive by Eva Hartley and I figured, why not? That book didn't just help me dream again - it showed me how to anchor those dreams in reality. Now, I’ve manifested opportunities I never imagined possible, and my mindset has shifted completely. If you’re frustrated like I was, don’t hesitate. Read this book. It will change everything ❤
What's that got to do with this video?
Been seeing a lot of Brian on the news… probably the best guy to prepare us for disclosure
The idea presented by David that life can be flourishing at larger distances and objects/planets if human being becomes that much more capable and intelligent is true in a probabilistic way with probability seeming dim in ratio.
Great video, nicely explained as always!
Reminded me why I love my life. Thanks for the video. Finished with teardrops in my eyes.❤
I saw Brian Cox last weekend in PA. He's a pleasure to be around ❤❤❤
I could listen to Brian Cox all day
Brian, this is a beautiful and insanely thoughtful way in explaining the universe. This really evokes my curiosity in learning deeply in astronomy and everything
I liked that very much, thank you!
I love these sorts of talks, and Dr Cox does a masterful job of illustrating this topic. He describes the distance from Earth to the CMB as 46B LY around the 9:30 mark, then says the "radius" of the observable universe is 92B LY. I believe he meant the diameter, if I might meekly correct him from my humble armchair.
Oh Brian, your mind is like the expansive Universe. Always enjoy listening to you.
I all respect to the attempt made here, i want to humbly say that, the youtube channel Epic spaceman, does the job of explaining the scales of universe much much better.
I love listening to Dr. Cox speak about the cosmos.
i wonder how such smart individuals like him tend to deal with a feeling of existentialism or existential crises. how does one not lose their mind thinking about existence?
I just love listening to Brian speak. So inspiring even for a simple lay person.
