What really amazes me, as a 64 year old, is how much we've discovered about our universe in just a relatively short time!
Thank you, Alex. As always, your videos make learning about space easy and entertaining at the same time.

*"This video is brought to you by Geologie"*
*Me, half paying attention:* No I'm pretty sure it's brought to us by astronomy

Imagine standing on a planet within the inner galaxy and looking up at the night sky.

That rotation diagram forming a 3-dimensional shape was reslly eye-opening for me! I feel like I understand it for the first time.

Alex, in the end of every video: "So, there we have it..."
Me:

Every time, it ends up with me abusing the reload button. Thank you Alex. It's always a pleasure watching your labor of love ❤

This channel is really amazing. I bet you've inspired a good chunk of the next generation of space scientists and explorers!

the universe is so incredibly beautiful. in high school i didn’t have a single class on astronomy (don’t know if it’s different in the us or elsewhere) so i had to do all my own research and i’m so glad I did. what a magnificent mystery we are

[PATMAN]

i was thinking 'only 8 minutes'? you crammed a lot of info in 8 minutes! gotta watch it again.

[SonKunSama]

This is one of the best channels on Youtube for me. You can clearly hear your enthousiasm and love for astronomy in your voice, all the while being perfectly clear and composed. This combined with the most beautiful pictures the universe has to offer make for a very enjoyable experience, even if one is not very interested in astronomy.

The best part about the video was to know about the 'rule breakers'. So intriguing and fascinating! They are cosmic rebels 🤘. They break rules at astronomical scales 😆.

[PaleBlueDot]

I'm waiting for the day when we will learn about the true nature of dark matter and dark energy, and unlock more and more mysteries surrounding them ❤

[Deeplycloseted]

I still have a hard time letting go of, “Dark Matter and Dark Energy are just excuses for something more logical that we are missing or don’t quite understand yet”.

The reasons they list for why Dark Matter definitely exists, are pretty convincing. Hoping the James Webb telescope is going to reveal revolutionary insight, like Hubble did.

The best part is, when we discover something new, the universe let us make the tool that we need to know it further using the discovery itself.

I can't help but watch every Astrum video more than once. Such a great channel. Best vibe and narration of any YouTube channel I know.

[buryyourdraws]

This was tremendous, multiple ideas that I've never heard before AND skin care tips! Seriously though these videos are a valuable resource

[DanielZajic]

Good one, Alex! Galaxies are fascinating macro objects with their own emergent qualities, and we still have so much to learn. The future is exciting.

[Andreschannel_SA]

Great video. Extremely informative and interesting. And the correct spelling of the English words used in the annotation did not go unnoticed either. You acquired a subscriber.

People: "Galaxies rotate counterclockwise."

Astrum: "Wrong."
