Idk if I'm just paying more attention to this stuff as I get older, but it seems like groundbreaking science is occurring at an ever increasing rate. The Higgs Boson, neutrino detectors, gravitational waves, JWST, first images of black holes, etc.

It gives me so much hope to know there are still so many blindingly intelligent people on this planet that just want to add to our collective human knowledge.

I'm 72, the idea that 17 yr old me could find and learn all this is grounds for hope.

"F*ck tha pole ice"
- IceCube

[SirHeinzbond]

the best way to explain the cherenkov radiation i have ever heard...

I worked at McMurdo Station in 08/09 and I was so bummed (still am) to not be able to make it to the pole because I wanted to see Ice Cube. It's such a cool project.

I can't help but feel a lump in my throat anytime Arecibo is mentioned. 😔

Hi astrum, I want to pour my heart into this comment. I am really long time viewer here (6-7years i think) I just want to let you know that you made me get fascinated in space and stuff around it so I am glad and proud to do so. I even crack some funfacts to my friends/family, because I gained the knowledge from your work which was and to this day and foward is just brilliant also that you are not like others promoting shitty brands and therefore you don't ruin the quality of videos because of it which is the one of the reasons that kept me watching you and let me tell you I am that type of the guy who just get bored after a while doing/watching the same stuff, but this channel and your team deservenot only my, but others attention too not only for the superior education than probably teachers around this topic, but also for learning about our place in the universe it self. I swear if you made a 4 hours long documentary video about a random rock in space I would watch it in one go ngl. 5 last words: Keep doing these videos please

EDIT: If someone found spelling mistakes ignore them, because english is not my main language :)

this explains how we keep finding crazy new stuff in the sky, seeing a signal to an event makes capturing them far easier. I really hope human kind doesn't ruin the opportunity to continue making these discoveries and making progress. We have wasted too much time and energy on war and needless conflict.

The most fascinating use of neutrino detection for me was the collaboration between physicists and archeologists in Egypt about 10 years ago, to determine what, if anything was inside a newly discovered cavity in the Great Pyramid. Egyptologists felt certain that there were cavities still to be discovered within the pyramid, but the government prohibited them from excavating and damaging the temple; the solution to prove or disprove their theory was through neutrino detection and their patterns beneath the floor in question.
If I’m not mistaken, the test proved that there was nothing inside the cavity and that it was just hollow space, thus preventing any unnecessary alteration or destruction to the structure.
Essentially, the scientists were using neutrinos as a large X-ray machine to determine if the cavity was empty space or filled with unfound treasures.

Great information presented in an extremely professional way. The text, monologue, graphics and animations are of a quality far beyond 90% of the AI stuff here on YouTube - MUCH appreciated. Bravo!

Hey Astrum Team! Just wanted to thank you all for hitting it out of the park as always.

The fact that a particle can create a sort of light shock wave is just insane to me! I would like to see some more in depth videos on subatomic particles and why the neutrinos behave this way, like under what circumstance do they interact with normal matter? They don't for the vast majority of time, so what causes them to sometimes?

It's all very interesting, and I love to see videos that show the tools we use to see this beautiful universe.

[annegajerski-cauley]

Very nicely done and well researched. I am thrilled to see comments reflecting the joy of people watching your content!
As a physicist, I would just point out two errors, one significant, the other a point of detail: 1) neutrino interaction cross sections are strongly energy dependent. While neutrinos from reactors, the Sun and other "mundane sources" have earth penetrating capture lengths, extremely high energy ones (of cosmic interest) will actually have capture lengths of less than a mile of matter. This matters for detector design.
2) the Czerenkov radiation process can be successfully described in classical EM theory (QM not necc in practice), which I state specifically because your discussion of the atomic interactions involved in bulk matter is a nice semi-classical description of the process in this regard. Best regards DKB

Don't ever change brother. Best space-related channel out there!

[Infinite_Curiosity]

I didnt know about them being used as an advanced alert to look at something in other wavelengths. That's awesome!

[peopleseethis]

My first thought to "picture a telescope" was legit "which kind?" 😆

[rdm]

Wow! I was so bad at science at school, didn't study it after school and kinda get what you're explaining here. You're really good at breaking these things down. You spark the curiosity in people related with Science man! Thanks a lot!

1:24 Honestly if you got to all the trouble of gaining access to a place that remote and inhospitable, you'd have to try really really hard to _avoid_ knowing what's happening there. Especially since it's one of the relatively very few things happening there to begin with.

[glubux]

Same music as Anton Petrov, don't know if it was on purpose but love you both.

[thirstyCactus]

That Amundsen-Scott South Pole Station would make a kick-ass LEGO kit!

This is what Astrum is best at, describing fascinating subjects about astronomy, the solar system and the universe in an easily understandable way.
