Large Quasar Groups

Quasars are the brightest phenomenon in the entire universe, able to outshine any type of star, and even entire galaxies containing hundreds of billions of them. Quasars are the product of monster black holes at the centres of large galaxies, and so when we find multi-billion light year clusters of quasars dotted around the early universe, we are forced to reconsider some of our fundamental assumptions of cosmology.

I remember when i spotted my first qusar with my telescope. The quasar’s name is 3C 351 and it is about 4.6 billion light years away. It took me about 45 minutes of looking through my scope and then reviewing my charts to make sure i am actually looking at a quasar. In my scope it looked like just another dim star, but it blew me away to think that i was looking at a mind bogglingly massive, bright, and powerful quasar that is 10% across the entire observable universe. It was incredible.

I really love how instead of just telling us what a quasar is, you took us through the decades of research it took scientists to figure out what was actually happening. Cheers for a fascinating video!

[jakobjas]

Every SEA video lately is like a full-on high quality documentary. Netflix should pick you up or something.

[LordTGaming]

More mindblowing than Quasars is how you can come up with this incredible quality in every Video. It is so on point that it truly outshines 99, 9% of all space documentary’s. Hats off to you. Keep up the amazing work

[sergoogle]

Glad I found this gem of a channel awhile back. The quality of this content always has me waiting for the next upload.

[joeschmo]

You’re doing something that the education system today is failing at. And that’s making these very interesting topics sound interesting. Thanks for all the educational and very fascinating videos!

[EpicMathTime]

Man, what great content. Every video is like a little cosmic audiobook.

[gwynethlowry]

I'm 17 and your videos have been a huge part of feeding my love of all things science and space, so I want to thank you for the amazing content. Thanks to people like you, I feel confident following my passions as I further my education and pursue a career. Thank you!

[kaffesniffarn]

Can everyone agree that SEA is the best YouTube channel talking about space in so many different and interesting ways?
So happy I found this channel

[kolyarage]

I love how I fall asleep every time I watch one of these, so I can watch it again next night. It takes me few nights to finally finish it. Interesting, but calming. Love it.

[followtheboat]

I'd just like say how much I enjoy your videos. I've watched similar YouTube space documentaries and yours stand head and shoulders above the rest. No drama and calmly narrated, extremely well researched, factually precise, fascinating, and great graphics to accompany it all too. Your hard work has not gone unnoticed. This channel is up there as one of the best.

[skj]

This is just top notch presentation. Your wording is incredibly well thought out and concise and the ordering of concepts is logical. Even more impressive is the coverage of recent papers that could only be distilled by someone very familiar with the subject matter. Your efforts are deeply appreciated.

[A_Spec]

Thanks SEA for making my evenings nice and chill with your dulcet tones

[carlz]

This is what really puts me to sleep at night! Nothing better then listening to the wonders of the universe as you slowly fade into the sleeping phase👍☺️

[Moucheron]

I'm 30 years old right now watching this. I've always been interested in space. For some reason I keep thinking about sitting in my grade school library back in 1997 and doing mundane tasks while this kind of stuff is happening out in the universe. It makes me feel infinitesimally small. Like I could be reborn a billion times and never get any further than bearing witness to these Universal events. It's quite humbling.

[sirspn]

Another day made better by your uploads. Endlessly thankful.

[Slenderman]

You'll always get multiple views out of me cus I love sticking your videos on cus they help me sleep.

[gnewsome]

Quasar Tsunami sounds like a teenage rock band that would perform at my local bowling alley.

[Corky]

Been here for awhile and just wanted to say thanks, your content is part of my day almost every day. Always looking forward to the next one friend, Salud!

I read every astronomy book I could get my hands on as a kid. I always thought quasars and black holes were separate. Imagine my astonishment and duh moment when I found out quasars are black holes. The thing from which light cannot escape is ironically the brightest thing in the known universe.
