Hello folks! Hope you enjoy it. This one is pretty wild. In two weeks we shall be exploring...how time began. So stick around, just getting started. Hopefully shall also melt your minds. Like, subscribe and leave a comment. Thanks!

None of the information in this was new to me, yet it was so well written and produced that I watched it all anyway and am still pleased. You didn't hype anything, you didn't oversimplify things to the point of stupidity nor go so deep that it would lose most audiences. Honestly, well done.

This channel and History of the Earth is honestly better and more interesting than documentaries on paid services. Keep up the great work!!!

The more advanced our research goes, the more we realize how small our hard-earned knowledge is. This exploration of our origins is an endeavour with no end point in sight. I'm just going to enjoy the journey with the scientific community for as long as my short life allows.
Thank you, for another episode which is a gem to the eyes, ears, and mind. You guys always put professionally produced documentaries to shame.

This series is written, narrated and produced with total professionalism. It should also be shown in schools.

Every time I reach the end and see that "Written by Leila Battison" line my mind melts indeed. For there is undeniable beauty in the clarity of the exposition, rythm in the preposition starting sentences, intensity in the moments of personal revelation scientists had in pursuit of abstract thought.
I like Matt O'Dowd dynamic and informal delivery, Sabine Hossenfelder's sharp no nonsense style and this pieces reach a height of litterary perfection to complement them.

I wish this series was required viewing in high school physics classes. So much of how physics is taught is geared only towards the rote memorization needed to pass exams not on understanding the context, framework and humbling beauty of our universe.

It seems to me much easier to memorize the details when you have the context of a story to hang those details on.

This series is pure poetry.

Beautiful narration. The tempo is absolutely spot on.
I've sampled many, many scientific channels, but 90% have narration that rattle on and on and on at a high pace, which I find very hard to follow and eventually starts hammering onto my skull. But I subscribed to this channel within a few minutes.
I hope you make many many more documentaries like these.

Cheerios to Leila Battinson for the script! That intro was really poetic, love it. David Kelly, man! you make sound epic that so many others would just read, thanks!

[Zymru]

cant believe i found this channel just by chance! hope your channel blows up in popularity soon, this is some of the best explained science content ive seen on YT

[sdgibo]

Thanks for producing the quality content that even most 'educational' TV channels have long discarded.

[WilliamDye-willdye]

Well researched, well produced. Bravo!

I may well represent too small of an audience to justify targeting, but if you want details about one audience member, here ya go. I'm not learning much anymore from "science for the public" material, but I'm not yet able to comprehend research papers -- not in theoretical physics anyway. Therefore my interest is in material that is, as I like to phrase it, "above my head but not out of reach". I want material that helps me finally read the research papers myself (or at least modern renditions of older papers which use updated graphics and naming). It's tough to survive in your field, so I don't mind if you target a larger audience instead.

The quality of your documentaries is top notch, I hope more people find your videos. I rewatch several of your History of the Earth videos and I am looking forward to do the same here. Keep it up!

[seraphinasowerby]

The level of quality and passion put into this vid blows my mind almost as much as the content of said vid. I hope more people find this channel, you defs deserve the subs and views <3

[Lillyyyy]

Seriously awesome video series. You brought up one of my favorite ideas of all time: light acting as both a wave and as a particle.. so strange and wonderful

[dror]

Surprising this channel isn't bigger already, i really appreciate the work.

[boryshacker]

i was so mesmerized by the perfect introduction to the topic! slow, consistent and guided.just wow!

[syntactyx]

Liked and subbed. This was such an ambitious undertaking and an incredible debut on YouTube. My recommendation would have been to explore in greater depth the role of cosmic background radiation in reifying the veracity of a hot, compact early universe, rather than just seeking to tackle the currently unknown (and possibly unknowable) nature of the planck epoch. Additionally, from what we know from the cosmic background radiation, the key to understanding the universe before the recombination era and all the way down to the planck epoch could lie in the cosmic neutrino background — something predicted to exist, but so faint and low energy it is almost impossible to detect. Perhaps these important ideas could be covered in the next video. Thanks for this. Brilliant work.

[FloozieOne]

Thank you so much for giving a definition of the Planck constant. I have heard of it mentioned in many documentaries but never understood what it was. Now that I do I can finally create a picture/constant in my mind as to what was going on in that tiny amount of space and time.

This channel and History Of The Earth are some of the only best channels on YouTube
