The Story of Cosmology: The Big Bang, Dark Matter, Dark Energy & the Great Mysteries of the Universe

Description: This is an exploration of the greatest discoveries in cosmology, the great scientists and astronomers behind them, and the still unresolved mysteries of the Universe at the most extreme scales of time, gravity, and distance across the deepest space.


The Big Bang, Dark Matter, the Cosmic Microwave Background, Cosmic Web Filaments, the End of Greatness, Inflation, Dark Energy, and there's still so many questions about the nature of our Universe.

Tonight we learn what the current lambda cold dark matter big bang model of the universe says happened from the first few seconds to the first few million years after the universe was thought have come into existence.

We learn what older cosmological theories evolved into and how our conception of light, matter and energy has changed over that last few centuries as our understanding of them has deepened.

We learn what the biggest mysteries of physics and cosmology still are and about the huge gaps in our understanding of the cosmic dark ages, the dark matter halos around nearly all galaxies, and how the still-mysterious phenomena of the big bang, inflation, and dark energy is propelling galaxies apart.

Thanks so much for watching. Let me know what you thought. -Rich

Sleepy brain says go to sleep but nerdy brain says must stay up and learn😩

But in all seriousness, thank you for helping me sleep and at the same time feeding my curiosity, these videos are top tier and are so very appreciated!

[tarottortoise]

Could you do a long video about whales? How they communicate, where they go, how much we don’t know about them yet? Thanks! 🙏

[Jennevere]

I've been dealing with pretty bad insomnia lately, and being awake in the middle of the night has started to feel very lonely. While they might not always get me to sleep, your videos keep me company while I'm awake, and I appreciate that.

[justtheaverageone]

There is something about your Voice when you speak calmly and softly, it just makes me feel right at home. Like when I used to listen to my father reading bedtime stories - almost 20 years have gone and passed since then but still you bring this kind of feeling... Like when you fell asleep in your parents car after a long day, you wake up "on that final turn" right before getting home, pretending you still slept and your parents carry you home-to-bed-feeling

[kavehsarkhanlou]

I'm not even a native english speaker but you talk so calm yet so enthusiastic I want to listen to you all day long.

[TobasscoJelly]

I don't know you, but I respect you hugely. Thank you for your hard work you put into these videos. Please dont stop making them!

[tupsurge]

the amount of time and work you put into these is insane. been watching and listening for 4 years. you never seem to disappoint. HAPPY EASTER!

[owaisahmad]

One of the best programs in recent times. Guest was incredibly knowledgeable and impressive. Very well summarized in the last minute by the host. Enlightening discussion.

[shelbyautherson]

i normally never comment but i have been falling asleep to your videos for over a year now and i genuinely love them! your voice is so soothing and it’s helps me get right to sleep. thank you for all the hard work!!!

[elpatator]

thought it was easter but it feels more like chrismas with this surprise drop. love seeing you update again rich! your videos are always appreciated.

[Flukew]

I am so glad you're back! Your videos always are obviously well made and high effort and they're super educating in a very easy to understand way, I appreciate the way you love to teach and learn yourself, and your energy is very calming, I could listen for hours. I want you to know you are doing a fantastic job and your effort is seen and appreciated. I watch your old videos frequently, anything from the Fermi Paradox and Kardashev scale ones to learning about the human brain. Thank you.

[ladydynamite]

Nothing gives me the tingles the way the original Cosmos series does. For a literature and languages person who finds science quite challenging to comprehend, there is something so relaxing about cosmology in particular because it feels deeply mysterious to me. Thank you for this, I will likely enjoy it over several watches!

[keithgordon]

Yes. Love the new drops. The content and the voice. Not even an asmr fan but this is pure gold.

[allanhoward]

Thank you so much !!! I say thank you because I have suffered from stress and anxiety for years even more so since Covid and all the high stress, and issues that came along with it. I have found myself sleepless exhausted and panicked in every aspect of my life lately. Your content is a saving grace for me to have some normalcy in my brain, that finally let’s be distress, zone out and peacefully fall asleep. Lack of sleep and distressing is one of the last serious health concerns we have not completely touched upon as a human society. I think you have a major part in helping me and I’m and I’m sure many others finally, rest, relax, becalm and Sleep ❤

[prettyblaq]

I listen to your ASMR so I can be smarter in the morning lol. I like how you speak to us as if we are physics students. It makes me feel intelligent.

[Susi_]

ASMR is the only type of video where the highest compliment i can give you is that i am never able to finish your videos because i fall asleep so quickly 😭I love your videos, your calm speaking voice is very comforting 🌱 i feel that listening to whispering for a long period of time can be a little too strenuous.
Sadly, i get a little too much anxiety whenever learning about the universe, its just the infinity of time that freaks me out, we are here on this earth for less than a blink, its too much for my tiny human mind to comprehend.
Would you maybe consider doing some videos about talking about philosophers or different philosophical viewpoints on things? Or maybe a video about the pyramids? I dont know, its hard to find topics that are interesting without being somewhat existential 😅

[Babewatcherbob]

One of my top 5 favorite channels. Keep up the fantastic work, man. 👏👏👏

[charles.e.g.]

This is absolutely extraordinary work my friend. I remember thinking when I was watching your previous video on the JWST that it was a masterpiece. And it was. But this incredible creation? There are no words strong enough. You have truly outdone yourself. Everything is perfection here: the narrative, production values, visuals, editing, etc. And all of this is on top of the tremendous amount of research and preparation that would be required for a project of this magnitude. This is one of the finest videos that I have ever seen on the topic of cosmology. Not just on YouTube, but anywhere. Yes. It really is that good. And then their is your voice. I can say without hesitation that you have one of the finest voices that I have ever heard. Not just on YouTube. Anywhere. And I teach voice, voice acting and acting. I also want to express my deepest gratitude to you for exploring this specific topic in particular. Even though I work in the arts, I have always had a great passion for the sciences. And I have a particular fascination with cosmology. When I watch/listen to phenomenal work such as this, I am always left with these incredible feelings of wonder and awe about this mysterious universe that we inhabit. I hope that you will continue to create beautiful and informative and inspiring works of art such as this one. You have a very real gift for this my friend. And forgive me if I am being presumptuous here, but I believe that you have found your calling. 🙏

[KrisBunda]

This is very high production values. Do you do this all by yourself? Where do you find all the quality visual assets? Do you collect them over time and catalog them? Or just linearly tackle finding and processing the imagery per topic, front to back of the video? You could make a great ASMR video just describing your production workflow. Seriously. And... It's a shame I always listen to your videos with my eyes closed! This is veritassium-level science edutainment (the highest praise I can think of).

All that said, AITA to ask if you would consider a whisper version? 🧐💨

another upload from Rich 😫 everytime i see it it’s a blessing
