Not being a particle physicist, I will have to watch this over a good few times before I'm confident to make comment without feeling realy dumb. 😂 I enjoyed it very much for my own sake and you have given me a couple of ladies to research for my 8 yr old granddaugther who wants to be a scientist. 👍
No need to feel dumb, especially considering there are those who would deny all of this in favor of the idea that most of science is false knowledge. This is not a small number of people, so at least you are leagues above them.
I'm wondering if the strong nuclear force broke away causing inflation because there was no actual mass at that point, then the Higgs field came about and stopped or massively slowed down inflation incredibly quickly because now all the energy used by the inflatron was being inserted into the universe using the Higgs Field to create mass, which instantaneously slowed down space that was expanding faster than light because spacetime now contained actual mass that gravity acted on and was pulling space back. Then as spacetime expands further and further and the universe cools, there is enough empty space to speed up expansion again and the space to matter ratio increased enough for the higgs field, matter and gravity to stop slowing it down as much. Or space is negative matter and therefore always pushes away the opposite of gravity. Or the super hot plasma and energy at the beginning pushed actual spacetime outwards until it cooled and couldn't push outwards anymore, describing inflation, then later empty space is dark energy as negative gravity and that's why you get the filaments, gravity pulling matter in and empty space pushing it out. Or.... I need to go to bed for a few years and think about what I said without any physics or mathematical knowledge, trying to pretend I understand anything about this amazing awe-inspiring universe we are blessed to live in!

This video is less than an hour and still more enriching than a lot of the documentaries out there on streaming services or tv.

YOU ARE FREAKING AMAZING Keep it up these are the best physics videos/ documentaries I have EVER seen. The way you dive into deep topics that no one else dares to explain, but yet you explain in a very simple and appealing way… I have no words to say, you are just AMAZING!❤
The only reason “you are freaking amazing” is because of God - and all you show of any marvel here is ONLY because you point at what is His and seemingly think this makes it somehow yours!?!
This is one of the few creators I instantly click on when I see a new upload. I've watched all of their videos multiple times and every single one has excellent quality. It's great to listen to before bed while contemplating existence as well.
I appreciate the human emphasis you put on the contributions of physics' more unsung heroes. I never knew about Galois, these obscure stories are what initially drew me to physics not the math lol. I'm a writer and like all story-tellers, I want to live forever through my stories but I find myself wishing more and more I was a physicist instead. The universe doesn't care about your though process, what makes sense to you or your world view/beliefs, it is what it is and it rewards those who look deeper and ask it questions, regardless who they are or where they are from. Its sad Noether, Wu and so many others never got the recognition (Nobel's) they deserved. But, I also think its beautiful that even without a Nobel when we talk of symmetries and forces with our new alien friends its the likes of Noether, Wu and their work that will be humanities ambassadors, why? Because the universe truly is symmetric where as our ideals might fall short. If you find an underlying truth about reality the universe itself will reward your efforts and deepen your understanding for it even if it takes the rest of the world while to catch up with you (think of Pauli, "I have done a terrible thing, postulated a particle that cannot be detected.) So thank you, truly your content is special! nothing else like it wish you and your team all the best you guys genuinely make TH-cam better just by existing. Understanding how and why a conclusion was reached is equally important as that conclusion so again, Thanks guys for making me fall in love with the stories behind the numbers. Without them they'd just be some quirky numbers scientists are fussy about and i probably wouldn't care.
I'm sure you are doing just as great and impactful a labor as the writers and story-tellers behind this video. It's just as you say; who cares about fussy scientists bickering about quirky numbers in journals stocked to the brim with academic jargon? The answer, of course, is that these are the closest things to objective truths we can arrive at in the field of natural philosophy. Group theory, among the likes of Darwin's theory of evolution, was one of many pivotal innovations in mathematical thinking which underpinned the rocket-launch of natural philosophy into the modern world from the stone and bronze ages of Platonic theory and Aristotelian discourse. I'm sure Pythagoras would've been among the bustling crowd ecstatic to witness the spectacle of the 3,000 ton controlled explosion that was the scientific revolution and it's now precipitously accelerating payload. Meta-mathematics is probably a better descriptor for it, because the definition of the conservation of momentum being mutually inter-dependent on the concept of translational symmetry indicates the connectivity and ubiquitous nature of the fundamental laws of physics; the language which describes each law is bound by logical axioms and rules which produce repeatable and universally consistent results, an artifact present in equal parts in the smallest part as much as the largest one. Whoever looks deeper and asks it questions, the universe rewards, even the hesitant and critical Pauli! Thanks for reading.
I so appreciate this channel and comments (exchanges) such as both of yours. I wish that I had become a physicist to better understand "all of this". Such a fascinating universe.
This is literally the only channel I ever picked interest in since the beginning of TH-cam wich I watched from discovery (2k subs) to now ( 500k subs) that consistently never disappoints. Also never read a single negative comment in the comment section
I've followed a lot of science channels but this video made me understand de fundamental role of symmetry in our current theories. Thanks so much, I'll be staying up all night thinking about how such a tiny asymmetry can still reflect a deeper symmetry 😅 but yeah honestly, thank you so much for this one, awesome work
I'm really enjoying this series, thank you. It really demonstrates how science is just a giant rabbit hole were every answer to every question leads to another question.
I can't believe how these History of the Universe videos can keep getting more and more beautiful. I love the work you are doing. I think this is the best one of them all.
I always wondered, what would have Galois found had he lived past his 21 years. Its baffling to me, at 30 years old, hearing of someone who lived way less than me, and yet in that short time, he brought so much to maths and science. His early passing is truly a loss for us all.
I cannot listen to most of those computer generated voices and so I am extremely grateful for these uploads, you know with genuine human narrating. It honestly sounds so much better so thank you so very much for your wonderful content.
Simply the best channel on TH-cam and Internet. I discovered the channel months ago by accident and I became addicted to its content. Thank you so much for this brilliant work combining history and science. The animations, videos and voice over are amazing. Can't wait for more content
One of my favorite channels on youtube. i love it because i dont even need to watch the video to understand it. it explains things with my level of understanding i can just close my eyes and listen to it
What an incredibly intelligent review of where physics stands today. Thank you Geraint for educating me further and provoking the right thoughts about the direction of today's physics theory.
I'm not a professional physics person but I am quite unsure of how or, more precisely, where exactly matter and anti-matter meet if they cancel each other out instantaneously? At any rate, great video as always.
I don't understand the question, maybe... They meet if they are pushed into each other. This doesn't appear to happen anywhere except where we do it on purpose, because there's no antimatter - at least, that we see.
Your contribution to history or more importantly human consciousness is incredible, if it resonates with only 1 person its enough. “Life” is so incredibly complex and wonderful and sad and bland and annoying and chaotic and hectic and morbid and beautiful.
I listen to these videos practically every day, I want the information to seep into my mind over time. Im always super excited when a new one drops. Thanks so much guys, your work is amazing
@@jimjones8736 Take the simple thing of mechanics. You cannot understand Lagrangians without basic calculus and the notion of conservation, or to put it another way, you cannot get something for nothing. And the animations in this video is clearly for entertainment rather than true understanding.
In reality, they would've noticed the problem as the exhaust plumes from their deceleration engines started mutually annihilating upon contact with each other, before they got anywhere near close enough to touch. Still, another excellent video. The discussion of magnetic monopoles puzzles me. I'm not sure why some physicists say they should exist, since it's already well-established that magnetic fields are generated by the _movement_ of electric charges. A monopolar field would require a static buildup of some kind of charge, in this case an electrical charge, and static charges are by definition _not_ moving.
Idk if they'd notice because of the excitement and/or pressure, but it definitely would be visible, yeah. They also probably wouldn't just disappear, just ruin their space suits and maybe their hands (or whatever the alien would use to touch)
@@FeeshUnofficial Matter Anti-matter reactions are one of the most energetic ones in the known universe pound for pound, its not that they disappeared, its more likely the pair of astronauts blew up. Which is why testing whether your counter parts are anti-matter by blowing smoke at them is a bit unsafe.
As soon as the separation of forces were mentioned as having happened at distinct times, I wondered if and when they could separate further. It's hard to imagine what the consequences of that might be.
They seperated at specific energy levels. Parts of the universe are now at the lowest possible energy, which means the floor has been reached. There are no unexplored lower energy levels for the forces to seperate out any further at.
@@vhawk1951kl To be honest and fair, I'm just another credulous halfwit. You know what? I was just thinking about that today. I imagine I'm somewhat credulous because of some psychological thing. So I suppose it's environmentally based but that's pure speculation.
The concept of universal symmetry is also why I believe the universe is cyclic. Fundamental aspects quite often entail life and death. Birth and rebirth of multicellular organisms, water cycles, birth and death of stars, that birth black holes etc. In the middle of all those cycles, you have the balance of symmetry
As an aspiring physicist, I have to say it's really² hard, the principle of least action is hard enough as it is but with lagrangian and hameltonian it's really a nightmare, excluding quqntum mechanics... Modern physics is already a nightmare Anyway,this channel is really helpful for those intrested in physics or aspiring physicist like me,its great explanation is really helpful instead of simply solving long equation without knowing anything the equation itself is saying,this explanation is really insightful in explaining the mathematics behind it and it helped me a lot
@@muahmuah4135 Thanks Muah muah! I did mean how tidal effects work over the Earth though. I didn't understand Patrick's Moore's explanation in his beautiful book 'Exploring The Earth and Moon' ( 1990 ), which is aimed at an 8 - 12 year old audience. Lol!
Distance is an illusion, there is but one point in space, one location, HERE. Also with time, there is one moment, HERE, with layers of dimensions. In this multiverse we are multidimensional beings of Light and the physical form we occupy is our avatar/vehicle. Everything is HERE NOW. 🌟
Yes. That gaffe really jumped out at me too... I guess I shouldn't be surprised that science-oriented TH-camrs may be unfamiliar with canonical literature of the culture they emerge from, but it does cast doubt on their interpretations of "the facts" generally...
Not to be picky, but at 37:48 you mentioned the words of Genesis. You actually quoted from John 1. Genesis 1 says "In the beginning, God created the heavens and the earth". No worries since both passages are wonderful and incorruptible. Thanks. I love learning this stuff. Martin Rees's book Just Six Numbers seems to go hand in hand with this video, too.
It's not that one can not get this information from some other source, but that the there is a train of thought that shows a deep understanding of the knowledge presented. The writers read through a pile of scientific papers and synthesized the information in them, adding their own perspectives and opinions. I do not claim I was able to follow all the ideas in the video (I have very shallow scientific training), but came away with a sense of knowing more than before and with directions I can follow up on.
Just found this channel and it is intensely interesting and informative. I knew nothing about sonar and had no idea sound could be so powerful! I would like to know more about this subject.
Nothing in the universe is hidden .... Unseen..unknown...incomprehensible...and every degree of unbelievable that could be .. Too small or too big...but never hidden...❤
Oh wow, you just made math so much easier for me. Never noticed a pattern of symmetry quite like that before. Looking forward to the rest of the video even more, now! Thanks.
You guys should do a channel: The History of Mathematics and Physics and just tell the thousands of stories of how the great men and women discovered them, and what it meant at the time. It's incredibly fascinating when you do this during your videos, I'd love to go deeper. So many had such tragic lives
well, it's hard to just have an outcome without something causing it there's no fundamental reason that curving spacetime should actually make things act in accordance with our ideas of gravity
@omar2886 General Relativity is ultimately a classical theory and does not comment on the quantum nature of the universe. So even though GR gives a beautiful (and accurate) geometric interpretation for what gravity is on cosmic scales, it doesn't tell us anything about what's happening between mass and spacetime at the level of individual fundamental particles, where quantum mechanics becomes important. What we do know from GR is the following: mass tells spacetime how to curve, and spacetime tells matter how to move. Based on the natures of the other fundamental interactions of the universe (the strong, weak, and electromagnetic forces), we think that some quantum particle must be communicating what we perceive as gravity in much the same way. Just like 2 electrons must transmit virtual photons between each other to communicate the repulsive force between them, many theoretical physicists believe that the graviton carries the gravitational interaction that ultimately leads to what we perceive as mass telling spacetime how to curve, and therefore how spacetime is telling matter how to move. Indeed, the comparison I make between electromagnetism and gravity specifically is on purpose - both are long ranged forces, both obey the inverse square law, and both seem to travel at the speed of light. If electromagnetism is carried by a massless particle, which in turn results in all these features, then it seems likely that gravity follows a similar path. Unfortunately, gravity is much, much weaker than all the other forces, so probing or confirming this idea is incredibly difficult and will take a long time to fully understand.
Art in my life? What use is symmetry to me? What did I think before coming here? What's happening then is everything going as planned? If no, something's going wrong, is everything still under my control?
Excellent presentation... In particular, your description of Emmy Noether's contribution was perfect... It is a shame that she died at such a young age...
This narrator has a soothing voice that isn’t drowned by the music. Hmmm… love the hand pan music. We already know the content is excellent. I think I’ll subscribe.
Maybe it doesn't know until it's observed? Maybe it's everywhere all at once and something something wave functions? Idk the stuff is confusing but this is a great question you have
Water streaming down a window runs into resistance, THEN adjusts it's path. Light doesn't seem to have to do this. Perhaps it does, but too quickly for us to observe?
I wanna hear more about Filaments... its insane... they are soooo big... maybe they could be accessed some how, maybe they are what we travel thru when we go into a wormhole? Fascinating that we can even detect something like that
There's this meme of "This isn't Sonic, this is my original character Blonic" and I couldn't help thought of that when you mentioned, squarks, selectrons, like "This isn't Quark, this is my original character from a symmetrical universe Squark"
Yet another masterful presentation. Informational narration, stunning images and a soundtrack that enhances rather than intruding. Thanks for uploading!
How can you deliver the history of the universe in 48 mins? Wow. How you pulled so many people, facts, equations, experiments and theories together is incredible. Then you blow me away at 37:31 where you introduce the perfect and symmetrical "super-force" using the Bible to illustrate the point. (correction in the reference-- the verse quoted was from Gospel of John 1:1, not Genesis"). Regardless, the point is made, and I believe that Super-force was involved at the beginning, is involved today, and will be involved tomorrow as the universe expands. Thanks again for the thought provoking and super-educational video. Along with the others, I look forward to more amazing content!
It's seems as though there are only two things perfect about that VERY early universe. It was perfectly symmetrical and perfectly uninhabitable, making it not really perfect for much at all.
Try as I may, despite being reasonably educated and a decent student I watch these videos over and over and comprehend absolutely NOTHING! Nobody's fault, you do a great job. It's just that quantum mechanics and physics are incomprehensible to some (or most) of us. Oh well.
I can remember when I first studied CP Violation and remembering also at the time [College of the late 1970s] and what we would learn from (most importantly- the Weak Force) in the near years to come. I wish to Thank You and partners who continue with a strong foundation for those who continue your efforts into tomorrow’s physics.
It's so hard to put into words not only the massively complicated (and in some cases literally inconceivable!) subject matter that you do in such an accessible way, but that you ALSO do so in a manner that consistently serves to inspire hope for humankind and gratitude for lessons we've learned--even those with high cost.

This is one of the few creators I instantly click on when I see a new upload. I've watched all of their videos multiple times and every single one has excellent quality. It's great to listen to before bed while contemplating existence as well.

I appreciate the human emphasis you put on the contributions of physics' more unsung heroes. I never knew about Galois, these obscure stories are what initially drew me to physics not the math lol. I'm a writer and like all story-tellers, I want to live forever through my stories but I find myself wishing more and more I was a physicist instead. The universe doesn't care about your though process, what makes sense to you or your world view/beliefs, it is what it is and it rewards those who look deeper and ask it questions, regardless who they are or where they are from. Its sad Noether, Wu and so many others never got the recognition (Nobel's) they deserved. But, I also think its beautiful that even without a Nobel when we talk of symmetries and forces with our new alien friends its the likes of Noether, Wu and their work that will be humanities ambassadors, why? Because the universe truly is symmetric where as our ideals might fall short. If you find an underlying truth about reality the universe itself will reward your efforts and deepen your understanding for it even if it takes the rest of the world while to catch up with you (think of Pauli, "I have done a terrible thing, postulated a particle that cannot be detected.) So thank you, truly your content is special! nothing else like it wish you and your team all the best you guys genuinely make TH-cam better just by existing. Understanding how and why a conclusion was reached is equally important as that conclusion so again, Thanks guys for making me fall in love with the stories behind the numbers. Without them they'd just be some quirky numbers scientists are fussy about and i probably wouldn't care.
I'm sure you are doing just as great and impactful a labor as the writers and story-tellers behind this video. It's just as you say; who cares about fussy scientists bickering about quirky numbers in journals stocked to the brim with academic jargon? The answer, of course, is that these are the closest things to objective truths we can arrive at in the field of natural philosophy. Group theory, among the likes of Darwin's theory of evolution, was one of many pivotal innovations in mathematical thinking which underpinned the rocket-launch of natural philosophy into the modern world from the stone and bronze ages of Platonic theory and Aristotelian discourse.
I'm sure Pythagoras would've been among the bustling crowd ecstatic to witness the spectacle of the 3,000 ton controlled explosion that was the scientific revolution and it's now precipitously accelerating payload. Meta-mathematics is probably a better descriptor for it, because the definition of the conservation of momentum being mutually inter-dependent on the concept of translational symmetry indicates the connectivity and ubiquitous nature of the fundamental laws of physics; the language which describes each law is bound by logical axioms and rules which produce repeatable and universally consistent results, an artifact present in equal parts in the smallest part as much as the largest one. Whoever looks deeper and asks it questions, the universe rewards, even the hesitant and critical Pauli! Thanks for reading.
Well said!👍🏻
I so appreciate this channel and comments (exchanges) such as both of yours. I wish that I had become a physicist to better understand "all of this". Such a fascinating universe.
Well put !
It is not the stories you write, it is how people interpret them that matters. If nobody understands the message it may as well be left unsaid.
This is literally the only channel I ever picked interest in since the beginning of TH-cam wich I watched from discovery (2k subs) to now ( 500k subs) that consistently never disappoints.
Also never read a single negative comment in the comment section
This is so good! Your storytelling ability is incredibly engaging and the images you use are great. Thankyou for continuity delight!
I've followed a lot of science channels but this video made me understand de fundamental role of symmetry in our current theories. Thanks so much, I'll be staying up all night thinking about how such a tiny asymmetry can still reflect a deeper symmetry 😅 but yeah honestly, thank you so much for this one, awesome work
I'm really enjoying this series, thank you. It really demonstrates how science is just a giant rabbit hole were every answer to every question leads to another question.
Thanks!
Awesome video! Perfectly explained I've watched hundreds upon hundreds of these kinds of videos and this was definitely one of the best
You're writing and the way you tell the story and explains the science, is some of the best I've ever seen/heard.
Thanksgiving came early, new video release! These are very well done I really appreciate the hard work that you and group you work with put together!
Enjoy the early feast!

Astronomy has to be the most exciting (frontier) careers to pursue these days. What we've learned in last 20 years alone is mind-blowing.
This helps reduce my anxiety and helps me sleep while still taking in this amazing information thank you for the amazing content, from Scotland ❤️
Thanks
Everyone involved in this channel - past, present and future - is freaking amazing. This is the absolute highlight of my day.

Danke!
I’m thankful for this channel and these amazing videos! Thank you HOTU crew for all you do! Happy Thanksgiving!
I can't believe how these History of the Universe videos can keep getting more and more beautiful. I love the work you are doing. I think this is the best one of them all.
I always wondered, what would have Galois found had he lived past his 21 years. Its baffling to me, at 30 years old, hearing of someone who lived way less than me, and yet in that short time, he brought so much to maths and science. His early passing is truly a loss for us all.
I cannot listen to most of those computer generated voices and so I am extremely grateful for these uploads, you know with genuine human narrating.
It honestly sounds so much better so thank you so very much for your wonderful content.
Simply the best channel on TH-cam and Internet. I discovered the channel months ago by accident and I became addicted to its content. Thank you so much for this brilliant work combining history and science. The animations, videos and voice over are amazing. Can't wait for more content
What are you on.
@@derkjh - I suspect there is a lot of fake/bought comments involved with this channel, tbh (?)
One of my favorite channels on youtube. i love it because i dont even need to watch the video to understand it. it explains things with my level of understanding i can just close my eyes and listen to it
Just a minor correction of detail. The verse at 37:53 is from John 1:1 not Genesis 1:1.
Great video! You always have such great content!
The irony lol science and religion...
What an incredibly intelligent review of where physics stands today. Thank you Geraint for educating me further and provoking the right thoughts about the direction of today's physics theory.
I'm not a professional physics person but I am quite unsure of how or, more precisely, where exactly matter and anti-matter meet if they cancel each other out instantaneously?
At any rate, great video as always.
I don't understand the question, maybe...
They meet if they are pushed into each other. This doesn't appear to happen anywhere except where we do it on purpose, because there's no antimatter - at least, that we see.
Your contribution to history or more importantly human consciousness is incredible, if it resonates with only 1 person its enough. “Life” is so incredibly complex and wonderful and sad and bland and annoying and chaotic and hectic and morbid and beautiful.
This is exactly what my mind craves, and you guys are doing it beautifully, I need more
I love your voice, your narration style is relaxing and engaging
What an incredible channel.. maybe the best astronomy channel, and that is really saying something with SEA and Cool Worlds out there
I listen to these videos practically every day, I want the information to seep into my mind over time. Im always super excited when a new one drops. Thanks so much guys, your work is amazing
I do that too....I'm not alone in this.....thanks!
Forget the videos. You won't understand any of this without grinding through and understanding the mathematics.
@@jimjones8736 Take the simple thing of mechanics. You cannot understand Lagrangians without basic calculus and the notion of conservation, or to put it another way, you cannot get something for nothing. And the animations in this video is clearly for entertainment rather than true understanding.
@@TomJones-tx7pb Yup.
Are you a relative of mine?😀
Usually I watch this channel when I'm falling asleep. I'm watching this during the day and I'm glad I did. Very educational!
In reality, they would've noticed the problem as the exhaust plumes from their deceleration engines started mutually annihilating upon contact with each other, before they got anywhere near close enough to touch. Still, another excellent video.
The discussion of magnetic monopoles puzzles me. I'm not sure why some physicists say they should exist, since it's already well-established that magnetic fields are generated by the _movement_ of electric charges. A monopolar field would require a static buildup of some kind of charge, in this case an electrical charge, and static charges are by definition _not_ moving.
Idk if they'd notice because of the excitement and/or pressure, but it definitely would be visible, yeah. They also probably wouldn't just disappear, just ruin their space suits and maybe their hands (or whatever the alien would use to touch)
@@FeeshUnofficial Matter Anti-matter reactions are one of the most energetic ones in the known universe pound for pound, its not that they disappeared, its more likely the pair of astronauts blew up.
Which is why testing whether your counter parts are anti-matter by blowing smoke at them is a bit unsafe.
I love this channel. It simply explains complex stuff without complicating. And the format of documentary catches the audience easily.
As soon as the separation of forces were mentioned as having happened at distinct times, I wondered if and when they could separate further. It's hard to imagine what the consequences of that might be.
They seperated at specific energy levels. Parts of the universe are now at the lowest possible energy, which means the floor has been reached. There are no unexplored lower energy levels for the forces to seperate out any further at.
@@vhawk1951kl To be honest and fair, I'm just another credulous halfwit.
You know what? I was just thinking about that today. I imagine I'm somewhat credulous because of some psychological thing. So I suppose it's environmentally based but that's pure speculation.
not if we are in a false vacuum@@jamespilcher5287
The concept of universal symmetry is also why I believe the universe is cyclic. Fundamental aspects quite often entail life and death. Birth and rebirth of multicellular organisms, water cycles, birth and death of stars, that birth black holes etc. In the middle of all those cycles, you have the balance of symmetry
the universe is not lazy, that is an unfortunate word, it's just efficient.
Exactly what I was thinking
Yes you are my favorite narrator! I love that little breathless fluctuation you add for emphasis!! Bravo my dear sir!
I say this every video, but I love this content and I adore the narration and editing in these. ♥️👌
This channel is a pure gem
As an aspiring physicist, I have to say it's really² hard, the principle of least action is hard enough as it is but with lagrangian and hameltonian it's really a nightmare, excluding quqntum mechanics... Modern physics is already a nightmare
Anyway,this channel is really helpful for those intrested in physics or aspiring physicist like me,its great explanation is really helpful instead of simply solving long equation without knowing anything the equation itself is saying,this explanation is really insightful in explaining the mathematics behind it and it helped me a lot
I don't even understand tidal effects.
@@mikefuller5577 Simply put it's push and pull due to gravity
@@muahmuah4135 Thanks Muah muah! I did mean how tidal effects work over the Earth though. I didn't understand Patrick's Moore's explanation in his beautiful book 'Exploring The Earth and Moon' ( 1990 ), which is aimed at an 8 - 12 year old audience. Lol!
Distance is an illusion, there is but one point in space, one location, HERE.
Also with time, there is one moment, HERE, with layers of dimensions.
In this multiverse we are multidimensional beings of Light and the physical form we occupy is our avatar/vehicle.
Everything is HERE NOW. 🌟
Other than confusing Gen 1:1 with John 1:1, this video is excellent!
Yes. That gaffe really jumped out at me too... I guess I shouldn't be surprised that science-oriented TH-camrs may be unfamiliar with canonical literature of the culture they emerge from, but it does cast doubt on their interpretations of "the facts" generally...
@David Peloquin lol "culture they emerged from"
Who cares about a bronze age book?
Keep crying nerd, reminds me of how people get all butt hurt about confusing star-trek with star-wars
@@PeloquinDavid go to sleep man
Not to be picky, but at 37:48 you mentioned the words of Genesis. You actually quoted from John 1. Genesis 1 says "In the beginning, God created the heavens and the earth". No worries since both passages are wonderful and incorruptible. Thanks. I love learning this stuff. Martin Rees's book Just Six Numbers seems to go hand in hand with this video, too.
So awesome. Excellent introduction on the symmetry of the Universe. Very well produced indeed. I definitely learned a few things. Thanks.
SEA squad here. Just discovered this channel and happy to have additional content that’s up to his level.
Hey man, just discovered your channel. Great video, I'm not a scientific person, but your visuals made me understand it well
It's not that one can not get this information from some other source, but that the there is a train of thought that shows a deep understanding of the knowledge presented. The writers read through a pile of scientific papers and synthesized the information in them, adding their own perspectives and opinions. I do not claim I was able to follow all the ideas in the video (I have very shallow scientific training), but came away with a sense of knowing more than before and with directions I can follow up on.
Just found this channel and it is intensely interesting and informative. I knew nothing about sonar and had no idea sound could be so powerful! I would like to know more about this subject.
Quite possibly the most epic opening to science documentary ever written. Breathtaking.
Nothing in the universe is hidden ....
Unseen..unknown...incomprehensible...and every degree of unbelievable that could be ..
Too small or too big...but never hidden...❤
The intro to this video is a masterpiece. So many ideas amd emotions packed into 3 minutes.
Looks like he quoted John 1:1 and not Genesis. Great video!
i also thought this was a pretty weird oversight considering the prominence of the quote within the larger essay's structure.
No it doesn't....pretty far from close...

The greatest joy any human being can find, while alive here, is in simply looking around and seeing. . .
Oh wow, you just made math so much easier for me. Never noticed a pattern of symmetry quite like that before. Looking forward to the rest of the video even more, now! Thanks.
You guys should do a channel: The History of Mathematics and Physics and just tell the thousands of stories of how the great men and women discovered them, and what it meant at the time. It's incredibly fascinating when you do this during your videos, I'd love to go deeper. So many had such tragic lives
actually they talk too much about people's lives and too little about the subject of the videos.
I still don't get why Gravity is considered a fundamental force rather than just an outcome of the curvature of space-time
well, it's hard to just have an outcome without something causing it
there's no fundamental reason that curving spacetime should actually make things act in accordance with our ideas of gravity
@@ppppppqqqpppEmergent properties are not unicorns; they are many. Take, for instance, life.
@ppppppqqqppp
therefore such statements are called postulates in physics and axioms in maths.
@omar2886 General Relativity is ultimately a classical theory and does not comment on the quantum nature of the universe. So even though GR gives a beautiful (and accurate) geometric interpretation for what gravity is on cosmic scales, it doesn't tell us anything about what's happening between mass and spacetime at the level of individual fundamental particles, where quantum mechanics becomes important. What we do know from GR is the following: mass tells spacetime how to curve, and spacetime tells matter how to move. Based on the natures of the other fundamental interactions of the universe (the strong, weak, and electromagnetic forces), we think that some quantum particle must be communicating what we perceive as gravity in much the same way. Just like 2 electrons must transmit virtual photons between each other to communicate the repulsive force between them, many theoretical physicists believe that the graviton carries the gravitational interaction that ultimately leads to what we perceive as mass telling spacetime how to curve, and therefore how spacetime is telling matter how to move. Indeed, the comparison I make between electromagnetism and gravity specifically is on purpose - both are long ranged forces, both obey the inverse square law, and both seem to travel at the speed of light. If electromagnetism is carried by a massless particle, which in turn results in all these features, then it seems likely that gravity follows a similar path. Unfortunately, gravity is much, much weaker than all the other forces, so probing or confirming this idea is incredibly difficult and will take a long time to fully understand.
Art in my life?
What use is symmetry to me?
What did I think before coming here?
What's happening then is everything going as planned?
If no, something's going wrong, is everything still under my control?
Excellent presentation... In particular, your description of Emmy Noether's contribution was perfect... It is a shame that she died at such a young age...
This narrator has a soothing voice that isn’t drowned by the music. Hmmm… love the hand pan music. We already know the content is excellent. I think I’ll subscribe.
Following the "path of least resistance" or "least action", I'm curious HOW that path is determined before hand.
Maybe it doesn't know until it's observed? Maybe it's everywhere all at once and something something wave functions? Idk the stuff is confusing but this is a great question you have
Water streaming down a window runs into resistance, THEN adjusts it's path. Light doesn't seem to have to do this. Perhaps it does, but too quickly for us to observe?
This is precious. I love it. Absolutely amazing content
I wanna hear more about Filaments... its insane... they are soooo big... maybe they could be accessed some how, maybe they are what we travel thru when we go into a wormhole? Fascinating that we can even detect something like that
It most likely detected us
There's this meme of "This isn't Sonic, this is my original character Blonic" and I couldn't help thought of that when you mentioned, squarks, selectrons, like "This isn't Quark, this is my original character from a symmetrical universe Squark"
Yet another masterful presentation. Informational narration, stunning images and a soundtrack that enhances rather than intruding. Thanks for uploading!
How can you deliver the history of the universe in 48 mins? Wow. How you pulled so many people, facts, equations, experiments and theories together is incredible. Then you blow me away at 37:31 where you introduce the perfect and symmetrical "super-force" using the Bible to illustrate the point. (correction in the reference-- the verse quoted was from Gospel of John 1:1, not Genesis"). Regardless, the point is made, and I believe that Super-force was involved at the beginning, is involved today, and will be involved tomorrow as the universe expands.
Thanks again for the thought provoking and super-educational video. Along with the others, I look forward to more amazing content!
It's seems as though there are only two things perfect about that VERY early universe. It was perfectly symmetrical and perfectly uninhabitable, making it not really perfect for much at all.
Try as I may, despite being reasonably educated and a decent student I watch these videos over and over and comprehend absolutely NOTHING! Nobody's fault, you do a great job. It's just that quantum mechanics and physics are incomprehensible to some (or most) of us. Oh well.
Its not lazy its efficient.
I can remember when I first studied CP Violation and remembering also at the time [College of the late 1970s] and what we would learn from (most importantly- the Weak Force) in the near years to come. I wish to Thank You and partners who continue with a strong foundation for those who continue your efforts into tomorrow’s physics.
This channel and Cool Worlds are the dopamine of existential wonder I need to get through my life tbh.
