Thanks! Always look forward to a new Let's Find Out video

[deluludoxepin]

BABE WAKE UP LETS FIND OUT POSTED (we’re gonna fall back asleep to this)

[bloop]

This was great, I enjoyed learning for about 20 or so min, then not only fell asleep but I could still faintly hear you in the dream and realized I was dreaming. So I got a nice lucid dream out of it too :)

Thanks for making this and not putting ads throughout. New sub!

[StaticBlaster]

It's always great to see a new video from you, bro. I love all these science ASMR videos especially all the astronomy ones. And I hope your family is doing well.

I started studying physics 2 years ago and your videos truly helped me making connections on what i learned in class and what it actually means, how these numbers represent reality. So fascinating!!

[ravenzbot]

Love the music behind this 💜 I love having a playlist full of asmr vids with the creator's choice of ambient background music so I don't have to simultaneously run a playlist

[awc]

Can someone please put in a good word for me with the people running the simulation? They did not do a very good job in the character creator when they made my face.

On a more serious note, glad to see a new video from you. Always a welcome sight.

[scottgall]

I’ve never commented on a video before. But really enjoying yours and this is so well done… so well I’m too engaged to drift off to sleep. A+

[sleepytime]

Your voice is so relaxing and the topics are always so interesting that I can’t decide if I should sleep or watch. Thank you for this gem ❤

[hannahroush]

This channel is the best thing I've ever found on the Internet.

[timburr]

not only do I get great ASMR but I learn so damn much from this! Thanks

[JimMcHugsU]

STAY AWAKE for this one. The narrative and graphics are outstanding.

[demolitionlover]

you always post exactly when we need you the most. much love to you and your channel 🫶

[SunnyBeetle]

Netflix get out of the way… the production quality of your videos is amazing !!!

divided into two segments. I used this prompt: "Summarize

bullet points were subsequently organized into sections with
