How to get black hole badges on Khan Academy

Dec. 7, 2011

The Black Hole badges are Khan Academy are legendary and unknown, so a lot of people want to know how to get them. There was a time when the code describing how the badges could be gained was online. At the time the Atlas badge was awarded for completing 150 exercises. But at that time there were fewer than 100 exercises on Khan Academy.

What Black Hole badges are there?

In addition to the three unknown badges, there are a couple of unique badges that only Sal has, and only Sal can get:

  • Is Sal - Which you can only get if you are Sal.
  • Galileo - Make 3000 videos (there are now other video makers, but none close to making 300 videos).


Of all the black hole badges, the most attainable is Tesla. This badge is awarded for getting 10 million energy points. Several people have got it now, some using various cheat to generate points. But there are enough videos and exercises that you can get this badge without cheating. This video show when I got the Tesla badge:

The Atlas badge is the most changeable of badges, always moving out of reach (except for the one time Ben Eater, lead exercise developer on Khan Academy got it by mistake). It was once for completing 150 exercises, then 250 and then 500. Now it has changed again, to another unattainable number. I suspect that when Khan Academy feels there are enough exercises to cover all of high school maths (or maybe one topic), then they will settle on a number. But for now it is not possible.

That leaves the latest badge, Artemis. I did look up the code for this badge when I was employed by Khan Academy and had access to their code. All I can say is that, like Atlas, it is currently not possible to get this badge.

LOL People are getting mad over a MATH PROGRAM. The black hole badges (such as Is Sal) that are impossible are just a joke...

Like JeBron Lames said, it's a math program! It's two badges! Y'all Are getting mad over a stupid two badges, (which u shouldn't be focusing on if u litterally can't get them), when you don't even pay attention to the fact that
a(this could be a joke)
b(khan provides free, good quality education for all people around the world)!
Just get over it!
it's a measly 2 badges! jeesh
P.S: Charlotte, how are they making khan look bad? It is 2 badges, and not too many people know about them. Plus, lots of people focus on the education part, and not so much on the badges.
Honestly, this is a pointless argument.

I checked out Sal's account, the first badge in her showcase is the Is Sal badge, so it isn't fake and the third one is the Galileo badge so they are real, just exclusive to her (except if you make 3000 videos for the Galileo badge)
