I retired a couple of years ago and finally have the time to dedicate to all the fantastically interesting subjects I've only been able to give a passing glance at before. Thank you.

One thing that black holes make me appreciate is just how much empty space there is between particles in normal matter! No wonder neutrinos can travel through the earth and not strike a single atom. At that scale it’s virtually all space! We have a very distorted view of what “solid” means.

It blew my mind when my mom wanted to show me a video that she thought I would like, and she put on one of your videos! You have independently attracted the approval of EVERY SINGLE PERSON in my family. We didn't even know that each other watched you. You've positively effected so many people with these videos. Teaching complex concepts with such elegance and simplicity is no small feat. I will always be grateful for you, your team, and this channel. Thank you, Alex, and thank you to the entire Astrum team. ☺

A weird thing about crossing an event horizon: part of the reason you can't go back is because the rest of the universe is gone. Time stopped for the crosser; so the rest of the Universe sped up until it more or less instantly reached the effective end of time (no other frame of reference).

Thank you Astrum for this unbelievably interesting content you've provided all that time, hope you keep going!

[sleepingbackbone]

Another gem from Astrum. Can't wait for a sequel. You're doing amazing work, and we are happy for sharing same space-time with you.

[SchmuckYourself]

Never been this early for a space video before...

This is without a doubt, one of the best and most underappreciated channels on YouTube. Well, I guess all of us who are subscribed to this channel definitely appreciate it properly.. but you definitely deserve far, far more recognition, Alex.

Alex, this video is exactly what I've been looking for to understand the process of a star transforming into a black hole. That was brilliant enough but then your explanation of lightwave propagation blew me away! I can't wait for part 2. The world needs more science communicators like you. Thank you.

[MegaCheese]

Thank you so much for being diligent with your music credits. Makes it so much easier to find those lovely ethereal tunes.

Astrum upload=day made better.
Seriously love your stuff, man. Thank you for all the effort you put into this channel

[that_guy_from_the_internet]

Dear Alex, i've been following your channel for a long time now and i am proud of the work you are doing here. The quality of your content is incredible, both the visuals/editing and the information you are sharing with us are perfect.

You, sir, are in my top 5 Youtubers.

Thank you!

You explaining quantum field theory actually got me to understand it now! I’ve been trying for so long to understand what it is, but your explanation is spot on! Thank you so much Alex and the Astrum team :) can’t wait for part 2!

Hey Astrum love all your videos! I have literally binged your videos for hours. From the narration to the graphics and even the choice of background tunes, especially this one (Strellardrone - Billions and Billions) is just from another world. The background tune is very subtle, but every time that tune starts playing I legit feel like I'm on a journey in space!

The timing of the music with the graphics and your narration is just sublime. I'm lost for words! Seriously amazing 🔥

Space never ceases to peak my curiosity. Black holes are literally magic, they break space and time and can immortalize you on their surface for trying to enter. It's straight up wizard magic..

[yosefcoopersmith]

The visuals in the video were really interesting. It was was cool to learn the name of the first discovered black hole, as well as the year it was discovered. The zoom-in on M87 was awesome! And the design overlay of our solar system with white text over the orange, red and black colors just looks really pleasing from a graphic design point of view, it would be awesome to have that frame as a poster. I really like the font for the text content you use in your videos to label your photos or references, its friendly looking and easy to read. Ive gotta remember to find it later!

[robertkerr]

I love your enthusiasm. The sheer joy in your voice makes your video's worth it.

[aroundomaha]

Wow! One of my favorite all-time episodes. Thank you for making a complex topic approachable.

[dundotta]

The narration with good background music, you can't go wrong.

[ernstkristianstlen]

I was looking for part 2. But just realized this was posted last night.
Looking forward for the follow up video
