This series is better than 99% of pay-to-view content out there, for free. Thank you so much for your effort

The quality of production for these videos is simply astounding, truly a gift on this platform. Your ability to breach into and enhance our imagination to explore these thought-provoking topics genuinely is deserving of great celebration!

It's an absolute JOY to see a new 'History of the Universe' episode appear. Thank you so much!

I took an astrobiology course in college and did a presentation on the meteor 'fossils' found discussed in this video. Microscopic balls of aligned iron were noticed, which are similar to Magnetotactic bacteria found on earth. Some organisms use magnetic material to orient and migrate along geomagnetic field lines. Using this mechanism they are able to find optimal oxygen gradients in the soil to thrive.

This is great! Thank you. My students ask me sometimes, if I believe in aliens. I always say, "Yes. But I just don't think they've been here." I used to love Ancient Aliens, but then I became a historian and realized that we just don't give ancient cultures enough credit. I have often wondered, "What if we are just the first one that's risen? Or what if intelligence only arises once in a million years?" It's a little depressing and reminds me of the movie As Good As it Gets. What if we are as good as it gets? But then I think, we've only searched such a small portion of the sky. Once scientist I in an interview with Neil Degrasse Tyson, said that of the sky, we have only searched the equivalent of a glass of sea water. You can't look at a glass of sea water and say that fish don't exist. Definitely something to wonder about. And be hopeful about.

It's hard to explain how much I love this content, it's incredibly well made and well presented. Hard science with a kind of romantic touch just makes my day

This TRshow channel is better than most of the stuff on mainstream channels like Discovery. Your voice, narration and scripts are absolutely spot on. The music is perfectly matched to the visuals and the information put forward is deeply interesting. Absolute bang up job. Thank you and please keep it coming. Liked and subscribed!

These videos with this voice is curing my depression. When I'm stressed out and have anxiety I used to pop pills not to get suicidal. Now I pop an episode of History of the Universe and my mind just instantly settles and my worries dissappear. I am truly greatful for this. I hope you the best. ❤️❤️🙏

Another banger of a video, David! This is by far, and away, my favorite channel on any form of media. Please never stop making these videos.

I love this channel. Everything they talk about is so interesting and is written about clearly enough for the layman to understand. Mr Kelly speaks so clearly that I don’t even need subtitles, and the editing is awesome. A lot of work goes into HotU and it shows, and everyone on the team does a great job

Cosmic and geological history are two subjects that I wish I could have learned more about back when I was still in school. Thank you for having two channels that go so far in depth while still keeping it in understandable terms

I love this channel! Educational, relaxing, thought inspiring. I use these videos to sleep every night. Drift off pondering about the subject matter. Then go back the next night to make sure I don’t miss anything. Keep doing what you’re doing please and thank you

I love this channel. Such interesting subject matter and it's presented in a way that even a smooth brain like myself can understand.

After watching one video, I was hooked. The series are well put together, meshing the history of quantum physics with new discoveries. Dont change anything and keep more videos coming!

I've been listening to these entire series. Wonderful work, Folks. Each episode is incredibly well crafted and the narration is absolutely eloquent. Thank you for this!

Such an inspiration this channel for ours! Among the few that live, breathe and prove quality > quantity 🏆. Always look forward to these videos - keep going and producing this magic 🧙🏻‍♂️ ✨.

Ok, so I've been binge listening to the entire series. Wonderful work, Folks. Each episode is incredibly well crafted and the narration is eloquent to the point of poetic. Thank you for this!

Paul Sutter wrote this! Impressed! He has come a long way and has honed his craft well. Without knowing who wrote this, I was loving how sometimes the author would introduce a story line and not let the viewer know how it fit into the larger narrative. I’d be familiar with the example, but it’s like a twist in how that fit into the developing storyline. Great approach to use from time to time. Greatly appreciate this channel.

Wow! The story-telling of Paul Sutter and the narration of Pete Kelly - what a winning combination!

I would like to thank those responsible for putting these incredible videos together, definitely my favorite channel involving the universe and space, the quality of the videos and the information provided is beyond top notch.

Thank you for the obvious care and quality of your videos. You truly have one of the best channels on TRshow.

I know this isn't an "ASMR" channel, but your voice is incredibly soothing and the content is tier 1.

You make incredible content and if it doesn’t put me to sleep it genuinely keeps me 100% engaged with the subject. I know that sounds contradictory, but I just don’t always have enough energy to be 100% engaged. I hope you enjoy making these beautifully crafted videos because they make me happy.

Love these videos - told with such clarity that an armchair science fan can easily follow the pretty massive concepts being shown. Great work! Hoping we're not alone and we just missed those radio signals somewhere...

I haven't gotten this excited over uploads since I was a kid. This channel has given me faith in the next generation of TRshow.

Wow I am actually learning a few more different perspectives on universal theories, literally, and I've read some Max Tegmark books to show you where I'm coming from. But this, it's up to date science discoveries is what it is, and it rocks 🤘 This channel never seizes to amaze!

I adore your videos! They are the kind of science documentaries that have become too rare.

This was absurdly fascinating. Never heard of this place before with the 10 000 year old monoliths.

Another beautifully written video. Amazing work, as always.

Very, very good content. EVERY episode is a spur to deep thinking. I have to say, on the "hiding in plain sight" angle, the universe itself pretty obviously saves information, processes that information, evolves the use of that information, establishes environments, exploits those environments, and generally does all the things we say "life" must do. On top of that it has invented creatures, at least once, capable of wondering about what it is up to. Perhaps (without prejudicing whether life, and even intelligent life, does exist not-too-far away) it is important to that educational process that we not have know-it-alls from the stars dropping in on us to short-circuit our unguided wondering.

I rarely comment on any kind of social media. But, I must admit .. I eagerly wait for your videos.. literally sometimes I go to your channel and try to refresh - thinking something will come up.. Kudos to you and your team! Keep it up 🙏🏼 Thanks

Another masterpiece of content making. Thank you so much for this wonderful channel.

Your videos are somehow straight to the point and filled to the brim with information. I love it

Thank you for this amazing video. It reflected many thoughts I've had to myself and it's vindicating to hear others speculate the same things regarding Dark Chemistry and Life

A fasciating insight into the many aspects of time travel, multi universes et al. I find such items another path by which man tries to show and/or prove that we are immortal in some way or other or that we are not just another 'insect' in a very small finite corner of the universe. I do look forward to more items as Colin Stuart puts the sunbject matter over so well.

For anyone who is actually curious, one of the best explanations for the Fermi paradox is given by cixin liu in his sci fi novel the three body problem. The book is fascinating and definable worth a read for anyone Interested. Netflix is also making a show so u can wait for that aswell.

One of the greatest channels on TRshow! Hands down! Amazing work!

This was worth the wait. Love your channel and always check to make sure I havent missed an episode

Your videos are exeptionally well made. Please make one about the whole nucleosynthesis ,specially the super nova part, and give us all the numbers : we love it!! . Keep up the good work.

This stuff never seems to seize to amaze. Grand research and a grand presentation. Thank you!

I absorbed everything, beginning to end, and loved every minute of it. Now I'll rewatch it to fall asleep to. Thank you for putting out a great video

when looking at what happened with life on our planet, i'd bet that we are quite rare, and even in a universe with billions of galaxies, if our rarity is normal, then any life like us that does exist would be spread so thin throughout the entire universe, that the likelihood of us finding it is absurdly small

Absolutely nailed it this time for me. I've been curious to the point of sleepless nights thinking about concepts involved with consciousness/awareness & I always end up in the same place in mind, which is to say "frustrating"😅 but I do have some fun thoughts on this matter and I really appreciate u covering it😊

One of your best, well done. This is the video to send to your family and friends for the all in one guide to life in this universe. :) Oh I have always been meaning to say.. give your script writer a raise.

I've watched several of your videos many times over. Still fascinated by the vastness of our universe. Thanks for putting such wonderful information on TRshow.

The quality of this channel and the fact that it’s free is absolutely astounding. It would rip us of this quality content but for yourself you really should think about signing a contract with a platform to have a paid version of this. It would upset me but it’s totally deserved. Idk how much TRshow pays you but discovery and various science channels should be giving you a blank check.

For approximately 6 months I have had all the HotU videos playing in a loop most of my non-working hours, including when I sleep. I have probably truly absorbed and understand about 30 to 40 percent of the content. I'll turn on something else when these videos become boring, but as of this writing I still find every video to be intriguing and thought-provoking.

Does it have to be a dichotomy between life and non-life? What if there are more, not less astonishing concepts in the universe like life, but not limited by any definitions. Really mind-blowing to think about it!

Excellent video - nicely narrated and produced with top video content. Most of it was already covered by Carl Sagan back in the 1970s but it was a fresh look at the subject with some new ideas. I think there have been many civilisations in our galaxy but they are long gone - even billions of years ago. It may not be possible for advanced civilisations to thrive more than 100 or 200 years due to internal warfare with nuclear or biological weapons. We invented such weapons only about 60 years after discovering radio. So any advanced civilisations died out - became extinct and so existed for only a blink of the eye compared to the age of the universe. That would explain the Fermi paradox. Look at how stupid we are right now - we are threatened with global nuclear war over 4 small areas of land in Ukraine that 2 years ago no one had ever heard of and from Russia which is already the largest country in the world so has plenty of land - so much land that most of it has no one living there. So we fight over pure greed for more of what we already have in abundance. That shows little hope for our long term future.

All of your channels help transport me to another place and another time. Truly grateful

I love these videos sooooo much, I watch and listen to them over and over again. Amazing channel dude. 👊

Your videos are truly amazing thanks so much another really good episode 😊

Hands down one of the best channels on TRshow the information and the way it's presented to the viewer is both captivating and entertaining I thank you greatly for your efforts and time in making such great content and for free a gift to all those with eyes to see and ears to hear please know your existence has greatly impacted and improved mine.

you guys keep knocking it out of the park. thank you.❤

Yay!! Thank you for what I'm sure will be another stellar, pun intended, episode. You're so great that these. Always fascinating to think about this stuff.

Excellent video, very interesting with very relevant information and analysis included. Thank you very much also for the high quality of content in this video.

Regarding Gobekli Tepe, don’t forget that it may be dated at over 10,000 years old, but we don’t know how long ago it was actually built. The date we have for it is from carbon dating some material left at the site that long ago, but that doesn’t mean it was built then. The site could potentially be much older.

Fantastic video. I am particularly intrigued by the concept of life arising during the initial seconds of the Big Bang. Since time does not exist, this whole civilization of potential life could "exist" for untold ages though to us only last a trillionth of a second? Tell me if I'm in the ballpark

This is one of my absolute favorite channels on TRshow. Just spectacular. Watched through the catalogue dozens of times. Thank you for all of your effort!

Amazing! Thank you for making these videos!

Brilliant as always. Thanks so much for your great work.

your videos are always amazing, can't stop watching them!

Enjoyable, informative content, well produced.

Another masterpiece of a production. Thanks for the education, and for challenging my understanding of the universe.

This conversation gets interesting surrounding viruses. I’m a virologist currently finishing my doctorate in immunology and geek out over this stuff :)

Would love to see life discovered traveling around the vacuum of space. How cool, yet terrifying would it be to discover huge silicone based jellyfish floating through the cosmos feeding off of light and radiation? 😂

Such a great insightful video, thank you History of the Universe!

Your videos are some of the best videos I've seen on the sciences. You should play the song in the beginning more often in the video. You did this in one of your early video on the universe and it was beautiful. The music is moving and matches the way you speak. Use it to make your speech and music crescendo into a piece of art and wonder. You've done it before. Regardless these videos are absolutely beautiful.

Quickly becoming my favorite YT channel. Def my favorite science related channel. Keep up great work 👏🏻

One of the best channels on TRshow without a doubt. Always great.

This channel is better than most studio documentaries, tv is dead.

so well done! this channel and the ones like it are the reason TV is dead. I would love to hear your input on the great filter, it would have fit nicely in this video

Loved it, grabbed my attention and didn't let go. Thanks for posting 🐄🛸

Hey keep the videos coming! You are very brilliant and I watch all your videos all the way through.

This channel is a real hidden gem. Awesome work! Greetings from Germany!

These questions of "where is everyone" and "are we alone?" always lead me to the conclusion that we should treat the Earth as unique, life on it as one of kind, and do everything we can to protect it. That means becoming multiplanetary, and bringing as much life along with us as we can, and spread it as far as possible. We very well could be the only intelligent life in the entire galaxy and we're the only species on this planet that can leave it. We have a responsibility.

The cure for insomnia isn’t the story he’s telling, but probably just the calmness of his voice.

As only sibling who doesn't practice family's religion I'm (too) often questioned "what do you believe in then?" This. And, due to what I understand about the current science, that every human is incredibly rare and significant. We are literally made of stars.

Dan Brown did a good novel on the meteor that is talked about in here. I’d love to see it as a movie

The idea of dark matter life forms has been explored somewhat in Philip Pullman’s His Dark Materials trilogy, though it’s not really hard science fiction and he doesn’t go too much into how that life came about (he’s not a physicist). I love those books.

Beautifully wrote and convayed. Well done. Very interesting.

Fantastic. You produce some of the best videos on TRshow.

Super super super. How can a You tube content creator better any documentary channel I can think of? This way of course. The content is perfect, it's not tied up in knots and hyperbolae and it's not commercial. It is just perfect. Thank you

This was awesome mate. Appreciate your work.

I think the Kardashev Scale should have a addendum for Type 0 planets. Type 0 planets 🪐 may come in four types: Alpha, Beta, Gamma, and Delta. Type 0 Delta contains either no life at all or only primitive life with no intelligent species. Type 0 Gamma are planets with intelligent species that lack signs of civilized activities. The intelligent species are hunter/gatherers with few tools and are generally nomadic. Type 0 Beta worlds have intelligent species that offer signs of civilization. These signs include permanent housing, trade, farming and animal husbandry, and complex social customs (including religious rituals). Type 0 Alpha civilizations are essentially Pre-Type 1 Civilizations. While they may not meet all the requirements for Type 1 status, there are strong indications of pre-Type 1 behavior. Type 0 Alpha civilizations not only show civilized behaviors, but technology is growing rapidly towards Type 1 status (such as space travel). I think most planets are probably Type 0 planets and most of them are Deltas or Gammas. But if we don’t destroy ourselves and we can break free and explore our galaxy, we may, from time to time, see the remnants and remains of Type 0 Alphas who almost made Type 1. However they couldn’t survive their own disagreements and conflicts.

Just FLUFFING beautiful work. So enjoyable to sit back and escape into this amazing oration. Thank you mate.

Love your videos. Could you maybe please make a video on galaxy formation?

Would love for this show to also be in podcast form

From what I read, recent archeological excavations (2021) have shown a water retention system and many several square shaped homes uncovered at gobekli tepe

The best feeling is when a new HOTU video shows up on my feed. Thank you for creating such awesome content!

God every time I watch your videos I get goosebumps. What a fascinating channel!

Wow! Another fantastic video from this channel…..really well done and written beautifully!

Sheer class. Thank you for such amazing work.

first a lemmino video and now a History of the universe upload, WHAT A BLESSING

I have a feeling that any intelligent life will eventually destroy itself or the planet it lives on. I think that we need another Carrington event if we’re going to have a chance of surviving as a species.

don't take this the wrong way, but this is an amazing sleep track, making stories out of science with smooth naration, so calming yet insightful, keep it up

Oh doooooddd!!! I've been meaning to watch miniminuteman's video about gobekli tepe! Stoked you guys came out with one too! Now I get videos from both my favorite earth history/archeology shenanigans on this boss subject!

Best video from you yet! Outstanding content!!

I love this channel but it also pretty consistently gives me an existential crisis lol
