Huge thanks to Antonio Padilla for inspiring the section on TREE(3) - his book is wonderful, I have already read it twice:

Cosmology and Physics are my favourite fields of learning. I am in my late 60s but still full of curiosity and wonder. This channel has long been and still remains one of my favourites. There was no such thing as the internet when I grew up and was in my 30s before I got my first computer and I believe this fact allows me to appreciate the current information age so much more than people who have never known anything else. The fact that a working-class guy like myself has all this knowledge and learning, not to mention art and culture at my fingertips, a mouse click away still excites and amazes me. The nearest thing to today, s communication network was the Starship Enterprise and its gadgets! I never imagined back then that such wonders would become easily available! I remember seeing their communication devices resembling today's mobile phones and laptops and thinking they would remain in the imagination of science fiction writers! How blessed we are!

No matter what I’m going through or what’s happening in the world, this series brings me peace. Perspective from the “pale blue dot”

Tree 3 sounds like an existential terror I'm not supposed to know about.

11 years ago before podcasts were as big as they are now, I was deployed in the mountains of Afghanistan and the only connection to the outside world was what we had saved on hard drives. No phone, no internet, just two way radio and paper mail. I had an hour~ long audio recording ripped from a CD that was all about infinity (which I have unfortunately lost the name to)- this video was the first thing I've heard since then that has combined the human and scientific aspects of this subject in a way that was able to stir up the feelings that my original recording was able to do over a decade ago. Thank you.

Understanding infinity isn't difficult.
It just takes forever.

TREE(4): allow me to introduce myself

Man tree 3 feels like something we should have been told about in school, that's some crazy ass information

I used to love Cosmology when I was in my school years, but I lost that passion because I didn't find people around me that would love the same, and no one really encouraged it. Thanks to YT and channels such as yours, I feel so excited listening to all of this. Got through the entire video and didn't feel like I've been listening for enough time. Thank you!

As my six year old daughter once said, “if you count to infinity, it’s gonna take forever.”

[korgscrew]

For me, it’s trying to imagine something that never ends. Everything we know of has an end. End of a road, end of a track, end of life. If there’s a wall, there must be something behind it. If the universe never ends, where is it contained? Just thinking what the universe is just gives me a panic attack 😂

The narrator's explanation of TREE(2) really is proof positive you can't explain something well if you don't understand it yourself. In fact, he doesn't really explain TREE(2), he just provides the answer, which I'm assuming confused anyone actually trying to understand the concept. Check out the video on the subject by Numberphile to get a much better explanation of the TREE function.

The beauty of these videos is that even for a second your mind wanders in a different direction you'll lose the grasp of what's going on. That's the kind of attention these videos deserve.

I'm 40 and in my heart, I am still a little kid amazed at every day, in every way, experiencing our beautiful Universe in this short lifespan. I pray that I am worthy of life. It's a gift not to be taken for granted.

One of my earliest memories is arriving logically at the frontier with the infinite. I was playing in the living room of my childhood home one summer afternoon and I remember having just watched some astronomy documentary on TV with my dad the night before. I was constructing a model of the universe based on what I had seen, starting with my local position on a planet orbiting a sun, sun orbiting a galaxy, and then as they say, the galaxies disperse and the universes expands. I arrived at some primitive notion of a ball getting bigger but understood that the universe seemed to be all there could be, and that for there to be a boundary, you needed a contrasting 'not-being' that defines the boundary to 'being', and the inevitable "What Is Beyond The Edge?(!)". I was scrambling to imagine a boundary to 'not-being' beyond the on to 'being' in order to 'capture' totality, but boom... It was a peak experience, I felt hyper perceptive and suddenly aware of the truly mysterious state that I found myself in as a human child. I often say it felt like all of my guts where falling out of my, kind of like looking up at an impossibly large object, or down from a height, like tingly gonads and butterflies in my belly. A defining moment for sure.

Anyway, I just wanted to share this article I found a while ago, it's from 1990, fully sourced with notes etc. Basically, it gives a really strong argument for the Big Bang hypothesis being based on a misinterpretation due to fundamental assumptions that have been experimentally and observationally disproven.
Given the alarming rates of megalomania and utterly petty and vicious personal attacks these neurotics rail against each other just for having differing opinions! Really, I think academia, specifically the physical sciences, are totally ridden with this. Additionally, when you understand how one culture's breakthroughs can become the foundational assumptions of subsequent cultures, and how early Greek thought undermines all of western intellectual pursuit, I reckon they probably just inherited that queasiness about something that can't be contained within the rational or imaginative faculties. I guess it sucks to know you can never know....

I personally find comfort in infinity because it makes death and monotony seem temporary on an infinite time frame. In a way it also offers us true freedom because we're not bound by a general greater meaning, we make something of everything given by the universe ourselves.

I found this channel right after the second video was uploaded, and it has been beautiful to see the extent to which it has grown. I struggle to think of another channel more deserving. Thank you for bringing us free, documentary-quality content, and thank you for helping to keep my love for science alive.

The fact that 'Something' ' exists rather than 'Nothing', means there cannot be a boundary of 'Nothing'. Hence time and space are infinite. Everything exists and all at once and infinitely.

[jaredc]

The universe is so inconceivably vast and humanity so infinitesimal that even if there is a limit to it's size the universe is functionally infinite.

This blew my mind. What an amazing explanation of what is and could be... according to us. Absolutely beautifully written and presented. Well done.
