It is amazing how atoms have assembled and taken human form to ponder their own existence.

[tamaracaldaroni]

So in reality we are just literally one speck of sand on a beach in the universe .
Blows my mind just how huge the universe/s are. This channel is epic... Love from Australia

Thanks for continuing to put these questions to some of the world's most insightful people. It feels somehow important and worthwhile.

My favorite closer to truth I have seen yet.

I absolutely love Robert's videos. His interaction with his guests is as though he's reading our minds. We basically see a flat horizon, blurred by distance to the point where we can currently see no farther, and for some hubristic reason we claim to know how far the universe stretches beyond our ability to see. Our curiosity is our greatest tool. The so-called sphere of observation, dependant on the speed of light and the age of the universe may be flawed. The inflationary period may have been far longer.

It’s like the TV pitch man, “But, wait! There’s more.”

[npcz]

For some reason I half expected Robert to be in the hot springs, still wearing his clothes

[krazeecatlady]

I go to bed every night and watch your channel on my tablet with headphones on..it's part of my nightly routine lol..these questions of why were here ECT, ECT have tormented me for as long as I can remember..thank you for trying your best to examine these questions.. brilliant videos thanks from ENGLAND 🇬🇧

[hemant]

It has to be endless/infinite, I can't even imagine any other possibility.

[owencampbell]

This is my favourite channel, with all the interesting questions and answers from the scientific point of view to the comments of regular people, taking part in the conversations and learning much from the professionals about the subject.
It's entertaining and interesting at all times.
My weird thought to the topic is, that we could be living in a very large body, and that there are multiple other bodies with the same structural conditions. Like in our body, we are some kind of bacteria, molecules, viruses or cancer cells that are about to destroy the organ earth.
There are good cells and there are bad cells, who is who?

[a.t]

Very interesting and thanks for the obvious effort putting this together

[nisarabro]

An Excellent Program and my Most Favorite One .

[williampaul]

I love the scripture that says- "We see in part. We know in part." That keeps my humble.

[Raptorel]

Best channel on YouTube with a new video, just what I needed.

[Robinson]

Those are some great opening shots, and how I loved the snowmobiling with Alan Guth part - that was great

9:43 Imagine the enormity of "pocket universes" being as small as pin heads or sunflower seeds, compared to our currently observable universe... Do that again, a hundred thousand more times! It's pretty hard if not impossible to comprehend.
