What Are The Hidden Rules Of The Universe? 

I don't think I have mentioned this before but thanks for speaking in a rhythm and a tempo relatively moderate with some dynamics. You earn every dime they are paying you to narrate this series. Everything seems to be presented these days at 100mph for fear of losing the viewers with no attention span. Excellent work my friend.

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. 👍

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. Thank you.

“The fundamental laws and the existence of matter truly arise from cracks in perfection.” Such beautiful words for a philosophy of everything.

Love how you tell the history of the universe. We are like a child listening to our father telling us good stories before we go to sleep.

I think “efficiency”, not “laziness”, is the universal way. ❤

Watching these videos has become a daily habit. Learning more and more about the universe, and physics in an exciting way. Thanks so much for bringing these to us.

Words can barely describe how incredible your videos are. I am so glad I found this channel.

So excited, we get another phenomenal science video. These videos are like a lullabies for adults who crave knowledge of the universe. Thank you so much for doing these!

You make the absolute best videos on RU-vid for this subject hands down! Your work is very appreciated and I can't get enough of your videos! Keep it up you have many fans!

I'm amazed about how many of the grand topics in cosmology and particle physics one can crank into a 50 minute video, props for that! It's an amazing summary of all the basics that were relevant for my PhD in the field.

Your videos are really great, extremely educational AND entertaining. Presented in a very pleasant narrative and voice, paired with great visuals. One of my favourite YT channels, thank you very much for your work and for sharing it with us.

The best current physics prose by far, professionally narrated and presented. Top quality stuff!

“Nature is lazy” is my fav quote from this video and such a succinct way to explain symmetry

This is what the internet should be, a modern day Library of Alexandria, full of all the fascination and creativity nature holds for us to explore. I have faith we will ultimately rise to understand how important it is for humans to have an open knowledge source accessible to everyone without tracking, surveillance or ads...or any ulterior motive.

When a video like this gets over 100k views in a few days, it's one of the few reminders I have that there are actually large numbers of curious, intelligent people in the world who enjoy learning and growing. Everybody I know 'believes' things, and seems to find 'reason' distasteful, if not downright offensive. So to my fellow viewers, thanks for existing, i guess... Stay curious! 🙏

I recently bought my first house and played all your videos while I painted the rooms and did some minor repair over the course of two months before fully moving in. Your videos are the best and are now forever part of my memory of my new home. I was born and raised in Hawaii but moved away. This video is so fitting for me to finally have made a comment with a Hawaiian name given to the super cluster. Thank you.

I have watched most of these videos in total fascination and awe of the intellects that are unraveling these mysteries. I don’t understand alot of this one but the graphics are incredibly fun to watch. At 70 years old I don’t have alot more time to see what answers new science reveals. What a long strange trip its been!

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!❤

My good sir, thank you for putting out Emmy’s name. If only more scientists or brainy nerds would give her and other unknown men and women of our collective understanding of how “this” all works. Thank you again!!

Incredible just how many different interesting physic concepts you can touch in one video. It isn't too heavy on technical explanations but perfect to awaken the interest of young, curious minds. Great channel!

Your videos hit the perfect balance of content being interesting and your voice being soothing. I put them on everyday before I go to bed. I get to listen to some fascinating stuff before I drift off to sleep around the halfway mark.

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

YES. Another video. I can't sleep at night without these videos.

Been watching your videos for a while. This is as good (if not better) than documentries out there. I feel like documentaries dumb down stuff for the audience and add in human drama just to keep the interest. 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're writing and the way you tell the story and explains the science, is some of the best I've ever seen/heard.

This is so good! Your storytelling ability is incredibly engaging and the images you use are great. Thankyou for continuity delight!

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!

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.

i love that macro symmetry and our entire concept of beauty and value, which sculpt both the universe at large and our experience of it, are just emergent properties of the micro symmetry that shape the physical laws that govern micro AND macro, with grand structures mirroring the small in so many ways. symmetry’s fundamental nature and the properties of emergence are so elegant it blows my mind.

I’m thankful for this channel and these amazing videos! Thank you HOTU crew for all you do! Happy Thanksgiving!

Awesome video! Perfectly explained I've watched hundreds upon hundreds of these kinds of videos and this was definitely one of the best

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.

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

The spin parity of neutrinos has got to be one of the wildest properties of the universe (thus far) So many brilliant minds over the centuries have had their work and equations funneled down into a single drop to try to get us to the next stage of discovery. Truly amazing.

These episodes are sheer joy and wonder.These are the things we as the human race should ponder to an understanding.

Brilliant stuff. Love this series. Thanks a lot!

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!

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 RU-vid 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'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

Hey man, just discovered your channel. Great video, I'm not a scientific person, but your visuals made me understand it well

This is the only channel I’ll like a video before watching it, because I know it’s going to be epic. Thank you for bringing poetic and enlightening content during the darkest times we’ve had to navigate. You’re helping build and maintain culture, and a refuge of mind.

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.

take a shot every time he says symmetry

Thank you! This was amazing to watch. Loved everything 🥭

You are responsable for most of my peacefull nights of sleep. You made a positive change in my life like you have no idea. Each night I put one of your videos. But not always from the begining. I always start from where I dose off, so I get to listen to all of it

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.

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 video is just absolutely incredible. Great work !!!

So awesome. Excellent introduction on the symmetry of the Universe. Very well produced indeed. I definitely learned a few things. Thanks.

This vid is so amazing that I'm only 1/3rd of the way into it and I've subscribed to this channel so hard. Looking forward to many more.

Absolutely wonderful. Great graphics too. Thank you very much!

This helps reduce my anxiety and helps me sleep while still taking in this amazing information thank you for the amazing content, from Scotland ❤️

I say this every video, but I love this content and I adore the narration and editing in these. ♥️👌

Thank you for this video. Got me thinking about some things not related but comparable. You do a great service!

This is precious. I love it. Absolutely amazing content

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 absolutely love your videos! easily one of the best channels on youtube... its only a matter of time before your subscribers are in the millions. excellent work as usual.

First time watching your channel. The quality of your documentaries are unparalleled. Subscribed immediately. Thank you!

I love this channel. It simply explains complex stuff without complicating. And the format of documentary catches the audience easily.

This is exactly what my mind craves, and you guys are doing it beautifully, I need more

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.

Brilliant!!! Keep ‘‘em coming. Thankyou.

This documentary is really exquisite at so many levels. Very very good work, thx!

Simply the best channel on RU-vid 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

Yet another masterful presentation. Informational narration, stunning images and a soundtrack that enhances rather than intruding. Thanks for uploading!

Thank you, this was so clearly and beautifully explained.

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.

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.

These are absolutely the best videos for this material I have ever seen. How do I help promote end encourage you and your developers to keep making these video. The explanations and details are outstanding. Just great work!!!

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.

What an incredible channel.. maybe the best astronomy channel, and that is really saying something with SEA and Cool Worlds out there

Great episode! Thanks for posting!!

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

Everyone involved in this channel - past, present and future - is freaking amazing. This is the absolute highlight of my day.

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!

these videos are magical. i listen to it at work. and i listen to them at night when i dont sleep.

Other than confusing Gen 1:1 with John 1:1, this video is excellent!

I haven't been watching for 10 seconds and I just want you to know I absolutely love these videos

Awesome video! Thank you! With a mismatch in the helicity of the (virtual) anti-neutrinos in neutrinoless double beta decays (should this decay modes exist), I believe that for certain proposed mechanisms you could distiguish between electron and positron one one side and anti-electron and anti-positron on the other side. Because electrons have mass, helicity is not the same as chirality. This would add another layer of complication in our understanding of the Universe, of particles and symmetries.

Just wonderful ! Giving me a much more understanding of the functioning universe. A +

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.

The best explanation so far on symmetry. Outstanding video, congrats!

i started with this video going to binge watch all ur content from the start thank u sir u are amazing

I love your voice, your narration style is relaxing and engaging

Best thing about this series? The narrator! Love his voice and articulation!👍🏻 Keep up the great work!

I still don't get why Gravity is considered a fundamental force rather than just an outcome of the curvature of space-time

This channel is a pure gem

This channel deserves to have 100mil subs

Looks like he quoted John 1:1 and not Genesis. Great video!

This channel and Cool Worlds are the dopamine of existential wonder I need to get through my life tbh.

This is a great video, one of the best I've seen. Thank you!

Keep up the good work. Absolutely amazing.

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...❤

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...

The intro to this video is a masterpiece. So many ideas amd emotions packed into 3 minutes.

wow, this is SO indepth!! Thanks for the video!

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

Following the "path of least resistance" or "least action", I'm curious HOW that path is determined before hand.

Thank You for the explanation & awareness , you given me a different point of view of (Symmetry/Asymmetry) it's connection to parity and how it may be useful to me in understanding (Information Theory) . .... Once again Thank You
