BREAKING NEWS: First image of a Black Hole captured by the Event Horizon Telescope!

✵✵✵✵✵What is a Black Hole?
Black Holes Explained (Astronomy)
Black Holes are super dense regions of space. They have such immense gravity that anything close by is sucked in, never to escape. Even LIGHT! That's why we call them BLACK HOLES.

Some black holes are small. Some are HUGE! There are stellar black holes, about the size of a dozen of our suns. Then there are SUPERMASSIVE black holes, that are the size of MILLIONS and MILLIONS of our suns! Scientists think there are supermassive black holes in the center of each galaxy. The supermassive black hole in the center of our Milky Way galaxy is called Sagittarius A. Recently, the Event Horizon Telescope was able to image the supermassive black hole in the center of the distant galaxy Messier 87. This black hole is known as M87, and was the first black hole ever to be imaged using the giant radio telescope EHT.

In this video, we talk about how Black Holes are formed and how we can detect them using various methods.

Channels like this are hidden gems on YouTube, like opals and corals under the sea

I really like the Socratica videos on astro stuff. They go a bit deeper compared to SciShow, yet remain very accessible to many. In this concrete case I also got an answer to something I wondered about rotating black holes.

In addition it's very well produced and the overall aesthetic is very calm, simple and elegant which I find again refreshing compared to the frenetic and chaotic style you usually find on YouTube.


Thanks for making it!

[LaunchPadAstronomy]

Outstanding work, Socratica. Your production values and explanations are several orders of magnitude above mine. I hope to grow up to be big and awesome like you someday :)

[jorgealejandropreciadolope]

I love your videos, Socratica!! This one is really well made and it summarizes in a very clear way our understanding of Black Hole Physics. It's so amazing that we have now seen (the event horizon of) one for the first time 🙂.

[DontYouSay]

I love this playlist so much!!!!
Thank you!!

[doomkun]

One of the first videos i've watched in a long time where I actually got new information.
Thanks!

[martinnogales]

Two thumbs up ever !!! Happy to acquire more knowledge, thanks a lotta dear SOCRATICA !!! God bless you

[boomcloser]

This is such an excellent video. As always, so interesting and well performed. I sincerely wanted to congratulate and thank Liliana, Kimberly and Michael for these videos and in general, this channel. I also noticed Liliana appears on the Spanish and Portuguese Socratica's videos, which is pretty impressive to see and hear, because of her highly refined languages. Congratulations again.🌿

Excellent video. I found this channel by accident but I am glad I did. clear, concise and very well produced. I can't wait to watch your other videos.

[nicholashylton]

Wow. Good video. A 'ring singularity' is phenomenon had never heard of before. I don't even think it's mentioned in Leonard Susskind book, _'The Black Hole War.'_

[rtt]

I have seen a number of vids on this topic, but this one is, hands down, the best. Great presentation.

[SindhuriVlogs]

you are my best teacher!
and thnkyou for giving such knowledge!

[bennaadjahanane]

Amaizing, informative and well presented. Big respect for channel team work.

[mu.makbarzadeh]

Thank you so much for sharing this clip!

[jackma]

Hi! I'm a huge fan of this astronomy playlist, do you plan on making more videos?!
Great intro by the way :)

[johnmanderson]

Everything is absolutely perfect... a real pleasure to watch and very informative, i gonna ad your channel to my Patreon account.

[lonskieg]

It functions as a recorder of every events in any part of the universe. As tiny as the flap of a butterfly. Every thought you have is recorded there and can be played back.

[JamBear]

This is better than Nova! I started your python tutorial to learn (it's amazing) and I am suddenly stumbling on all this amazing content! Highly recommending this channel to everyone at work these days.

[vicg]

Awesome Chanel. I learned more about black holes in one viewing than I have collectively in all the History and Discovery channel programs combined, and without sensationalism or dumming down. Please keep going with this excellent work.

[arsereg]

I've loved all your videos!!! I'm hooked! :D
