Black Hole badges

If seen, please write your ideas about this topic and how we may address it.

well, black hole badges basically flex your learning of skills, not luck. I have been using a different account to grind Maelstorm and I'm only ~30% done with it. believe me, you have to put a lot of hard work into getting Black Hole badges.

Awards: As far as I know, the badge itself is an award since these are SO rare!

I commented in one discussion board on KA all the BHBs and how to get them. Here's a brief summary:

Atlas: Master 5000 Skills (very hard)

Artemis: Master 7500 Skills (impossible)

Tesla: Obtain 10M Energy Points (moderately hard)

Maelstrom: Attain Proficiency in 4950 Skills (hard)

Herculean: Attain Proficiency in all skills to date (incredibly hard)

Galileo: Create 3000 Videos (impossible normally)

Is Sal: Be Salman Khan (impossible obviously)

I was invited to meet Sal in person when I got Maelstrom, it was really cool, we talked a bit and took pictures together.

Who has the most black hole badges?

good question I would like to know too, but its's probably Sal Khan and private users

Me and KEVIN are two black hole badges 

Which ones do you both have?

I'm assuming Maelstrom and Tesla

It is funny how KEVIN has 2 black hole badges but chooses to put the Droplet badge on his showcase instead.

You got to meet sal in person Yechidoth Taw Immodicus!!!

Thats actually really good thing for your college, and how long have you been using khanacademy for?

Can you tell me a bit more about your experience talking to sal, and how I could maybe get a chance?

Well I have Maelstrom. Also Olamoth Artyom Tetrakleitos that's awesome :)

I'd think that Sal Khan has the most BHBs. He has Is Sal, Galileo, I believe Tesla, possibly even Atlas but I'm not sure

xyzyyxx, did you meet Sal?

Aaryan Bhattar Nope

oh cause Yechidoth Taw Immodicus did.

Guys check out my question and theory about the Is Sal badge

It may be true

Yes Advait Pillay i jhave Tesla and Maelstrom in my showcase, currently I'm trying to get Atlas, but I don't even know if it's actually possible by now, if not, probably will be in the future.

Yeah, the profile shows 2 Black Hole badges, we know for sure one is Tesla but the other one we don't know, probably Maelstrom, but can be other, who knows?

Olamoth Artyom Tetrakleitos Check the KA wiki under Atlas. I've updated it.

Hello,Aaryan Bhattar, we talked for a little while, for one or three minutes. Unfortunately, I didn't have much time to talk in depth as I would have liked, since he is a very busy man.

Yeah I saw that! congrats xyzyyxx you're level 100 or higher apparently I, Kevin and you are the only public users who have Maelstrom, I wonder which level are you guys exactly.

Olamoth Artyom Tetrakleitos Thank you! I'm actually level 100, 9 skills in

That's really impressive! you probably will be invited too I guess, I'm exactl at 50 from 110 on Level 110 right now, I wonder how many levels there are if a Max Level exists, what I can say is, the last level is at least 111 or higher, but I think it's at least 7,000, since in the Maelstrom anouncement community post moderator said there are at least 7,000 available skills to public master (there are probably unlisted skills to master also)

There should be at least 118 levels, according to that post and some WolframAlpha

Exactly! cuz: (118/2) x (118+1) - 118 + 97 = 7,000; so in that time (a year ago) max would be at 97 skills at level 118, but it's probably higher now, who knows if Artemis is already possible to obtain?

It probably might barely be possible

Btw I found a really cursed badge: https://www.khanacademy.org/badges/1-week-streak

Last I checked, the current registered skills on KA hovers at about 7270. If this statistic is still correct, that means that the maximum attainable level using Gauss's triangular number theorem and my own stacking triangle factor theorem is Level 120 with 10 skills left over. I'd say this is about right. The reason Atlas is so difficult even now is because it requires mastery of 5000 skills. As many of us know, many of the KA courses don't have a "Proficiency" or "Mastery" rank, and only give the effect of Proficiency upon completion. This means these courses do not count towards progress for the Atlas badge. Back in the day, us legacy users had a portal called Missions. This Missions portal organized the courses (mostly for math) into an organized group with progress tracking and a bunch of statistics. The reason for removing the Missions portal was that KA was moving towards a more stable foundation for the source code, Python3, while the Missions portal was built entirely in Python2 and because of how complicated it was and many tricks they used that are unavailable in Python3 they couldn't get it transferred easily. So they retired the portal, as well as many features and badges that become unattainable or difficult to obtain. One of the features of the portal I particularly enjoyed was that it told you exactly how many skills you had attained Proficiency in as well as how many you had Mastered. Furthermore, if you got close to a Skill Badge such as Newton or Galileo it would tell you how many more Mastered Skills you needed for the Badge. Legends of the day even said it did the same for Atlas, although Atlas itself was just barely unattainable as just before the close of the Missions portal KA had about 4600 skills that could be mastered. Nowadays, looking at the skills that lack a progress meter and thus only Proficiency can be attained, I can estimate that there are some 6000 skills in KA that you can attain Mastery in. This is above the requirement for Atlas, but the badge won't be easy nonetheless as hundreds of these skills are in hard-to-reach places. Artemis requires 7500 skills and even if every course in KA today was fully able to be Mastered, the badge would still be impossible. A member of the KA team has estimated that they should reach 7500 skills sometime in Spring of 2026. If you have any more questions, feel free to ask.

Where did you get the 7270 number from? I'm just curious
