Welcome to the Black Hole Badges tips. According to Khan Academy, Black Hole badges are legendary and unique. 4 out of 5 are still impossible for most users to earn and their requirements are unknown.
Tesla
To earn Tesla, users have to earn 10,000,000 energy points. One way to get the badge is to watch at least 5000 videos and acquire at least 300 299,792,458 Meters per Second badges in exercises. This is the only Black Hole badge that does not give users any energy points when obtained.
Atlas
To earn Atlas, users have to master an unknown amount of unique skills (used to be 150, then 500, and now is believed to be 1500, however, every time Khan Academy reaches the Atlas requirements they highly increase it). Ben Eater has this badge and there is a rumor that he accidentally gave it to himself.
Artemis
To earn Artemis, users need to master 60,000,000 skills; however, this is only speculation.
Galileo
To earn Galileo, users have to become a content creator who records 3000 videos on Khan Academy. Because of the low demand for this position, it is impossible for most members to get the badge.
Is Sal
To earn Is Sal, users have to be Salman Khan - the founder of Khan Academy. Obviously, it is impossible for any member (except Salman Khan) to get the badge.
