"Light likes to think it is the fastest thing in the universe. But no matter how fast light travels, the darkness is there waiting for it" - Terry Pratchett

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.

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

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.

"scientists say TREE(3) is the largest number man has ever imagined" 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

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

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.

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.

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 😂

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!

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.

The probable dread on their faces back then when they farted is so hysterical to me

Imagine being so immersed in mathematics that the concept of infinity causes a mental breakdown.

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.

What an absolutely brilliant explanation of the possibilities of the existence of anything our minds can (or cannot) imagine.

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.
