I listen to all of your channels on repeat and have to say - you have an immense gift to be able to convey all topics you speak on with such clarity and calmness, while staying grounded in reality. That it makes difficult topics appeal to everyone. You and your team do great work - keep it up!

I'm no expert, but I know a thing or two about getting lost in the elegance of a problem and over-engineering a solution until it has no practical value. String Theory has always felt exactly like that to me.

[PlakaDelos]

While not a theoretical physicist or a mathematician of this caliber, I have, for years, followed the development of the various theories. The explanation of ideas presented in this video is the clearest I have seen. And for the first time, I understand how the theory works. Thank you.

[braticuss]

I truly appreciate this channel. Great writing, great narration, not too technical, but not too dumbed down either... It's perfect.

[theziggurat]

These docs are well-written, expertly narrated, and in my opinion, far better than anything produced by major tv networks or streaming services in recent years. Much thanks to the creators for this content. Keep doing what you're doing and I'll consume with fervor.

I could listen to hours upon hours of this and never get tired. Sad how so much of society dont care about this sort of stuff anymore. Its literally learning how the universe works how cool is that???

[mx.fuzzypants]

You are so good at explaining things. Your voice is so soothing and simple, no extreme accent, and easily understandable. Also, the analogies you choose are amazing. For example, one analogy you used was “Like building Lego with boxing gloves” to describe our technology being too big to observe small things, and was super simple to understand. I fall asleep to your videos and they are amazing to think about. I hope you keep doing this and you find success in it.

Could you PLEASE acknowledge both the writer and narrator of this fascinating and remarkable video? The explanations and pictorials are so remarkably clear and coherent that they reveal a depth of linguistic and diagrammatic expertise not normally gifted to us ordinary persons! Without being unnecessarily submerged in esoteric and arcane mathematics, I can now understand the (theoretical, at least) structure of the environment within which we all experience reality!

[verafleck]

I never had such a clear explanation. You are a really good educator.

[mickeyb]

These videos have deeply broadened my understanding of physics, cosmology, and the greater universe. The way you break down complex technical terms is incredible, and people with non-scientific backgrounds like myself can really expand their knowledge of the universe. Thank you so much, and please keep these coming!

21:41 Your videos are alway so clear and accessible it makes laymen—the average person—feel as though we’re a part of the conversation, rather than just on-lookers. Thank you for that—the inclusive way you present the science!

[FFNOJG]

I literally check constantly for updates from this channel. it is my favorite channels on all of YouTube. I seriously believe that you, and your team make the best content in the world. On any medium plausible.

[dgareandro]

Just epic!!! You lads managed to put in simple words very complex and fundamental concepts of how our entire Universe works. This channel is definitely among the top 🔝 five best channels on YouTube that actually address this fundamental physics problems in a deep meaningful manner 😁👏👏👏👌

[TheDunestyler]

I'm an experimental physicist and there's one thing about String Theory and also M-theory which has to be said:
Every prediction so far made by both that has been possible to test has been proven wrong.
After them being proven wrong, the theorists behind it then set out to modify the theory, so that it says the same or a similar thing, just reducing the scale to one which cannot be proven either right or wrong at the time, and when that is proven incorrect, they then set out to repeat this.

So, to me, M-Theory stands for Mysticist Theory.

[rameenana]

To a science enthusiast such as my self who knows very little about physics, this explanation… or rather explanations about String Theory was easy to understand (at an elementary level) and utterly enjoyable to learn. Thank you for this. Your work is appreciated.

[emergentform]

Wow, this vid is incredible. The subject matter, the way it's explained, the graphics, bloody brilliant, love it!! Much love and appreciation to the creators.

[jeancorriveau]

I subscribed to this channel a few months ago. The narrator makes me understand in a deeper way than other channels. Well done!

[vaels]

Great video! One thing I would appreciate would be actual related equations shown on screen more often in place of some of the b-roll of swimming through a sea of unrelated mathematical expressions

[jorispattyn]

History of the Universe is by far the most interesting, and enlightening scientific series I ever found on the Net. Keep going, please!

[BDB]

I can’t believe your videos are free. Seriously man, you are straight up gifted to be able to convey this stuff to people. Bravo! I’m here to stay!
