Black hole badges on Khan Academy represent the absolute pinnacle of achievement on the platform. They are legendary, shrouded in mystery, and designed to be nearly impossible for the average user to obtain. Unlike meteorite, moon, earth, or sun badges—which track progress, streaks, and mastery—black hole badges require extraordinary dedication, massive time investments, or specific historical circumstances. If you are hunting for these elusive trophies, you need to understand exactly which ones exist, the specific requirements for each, and the realistic feasibility of adding them to your profile.
The Legendary Tier: Understanding Black Hole Badges
Before diving into the specific requirements, it is crucial to manage expectations. But khan Academy currently features five distinct black hole badges. They are the rarest awards in the ecosystem, often taking years of consistent effort to tap into. Most users will never see a single one on their profile, and that is entirely by design. These badges are not meant to be "grinded" in a few weeks; they are lifetime achievement awards.
The five badges are:
- On top of that, Atlas (Content Creation)
- In real terms, Artemis (Exercise Mastery)
- Worth adding: Tesla (Video Consumption)
- Black Hole (Energy Points)
We will break down the requirements and strategies for the four currently obtainable badges, plus the history of the fifth.
1. Atlas Badge: The Creator’s Summit
The Atlas badge is unique because it cannot be earned solely by learning. So it is awarded for creating content that gets added to the official Khan Academy library. Specifically, you must write an article or create an exercise that passes the rigorous review process and is published to the main site.
How to actually get it:
- Apply to be a Content Creator: Khan Academy does not accept unsolicited content from the general public anymore. You must apply through their official volunteer or contractor channels when applications are open.
- Subject Matter Expertise: You typically need deep expertise in a specific academic field (advanced math, science, humanities, computing).
- Pedagogical Skill: Writing for Khan Academy requires a specific voice—clear, encouraging, and aligned with their mastery learning philosophy.
- Review Cycle: Content goes through multiple rounds of editing, fact-checking, and formatting before publication.
Reality Check: For 99.9% of users, this badge is unobtainable because it requires a professional relationship with the organization, not just student effort.
2. Artemis Badge: The Mastery Marathon
The Artemis badge is the most "achievable" black hole badge for a dedicated learner, though "achievable" is a relative term. It requires you to master 7,500 unique skills.
The Math Behind the Madness
As of the current curriculum, Khan Academy hosts roughly 10,000 to 12,000 exercisable skills across all subjects (Math K-12, Science, Computing, Arts & Humanities, Economics, Life Skills, etc.). To get Artemis, you need to reach "Mastered" level (the highest proficiency tier) on 75% of the entire platform’s curriculum.
Strategy for the Determined
- Start Early, Stay Consistent: This is a multi-year project. If you master 10 skills a week (a heavy load for a student), it takes roughly 14 years. If you treat it like a full-time job (50 skills/week), it takes ~3 years.
- Course Challenges are Key: Don't just practice individual exercises. Use the Course Challenge feature at the bottom of every course page. It efficiently tests you on multiple skills at once, rapidly leveling them from "Familiar" to "Proficient" to "Mastered."
- Focus on High-Density Courses: High school math courses (Algebra 1, Geometry, Algebra 2, Precalculus, AP Calculus) and AP Science courses (Biology, Chemistry, Physics) contain hundreds of skills each. Clearing these provides the biggest chunk of progress.
- Don't Neglect "Small" Courses: Courses like "Grammar," "Constitution 101," "Financial Literacy," and "Internet Safety" have fewer skills but are quick to master and add up significantly.
- Maintain Mastery: Skills can decay if you don't use them. You may need to re-master skills periodically, inflating the total count required.
3. Tesla Badge: The Video Archivist
The Tesla badge is awarded for watching 3,000 unique videos on the platform. This sounds simpler than Artemis, but the volume of unique content required is staggering.
The Content Landscape
Khan Academy has thousands of videos, but many are short (2–5 minutes). That said, "unique" is the operative word. Re-watching the same video for review does not count toward the counter. You must watch 3,000 distinct videos And it works..
Strategy for Completion
- Curriculum Completion: The most natural way to earn this is aiming for 100% course completion across every subject. If you genuinely complete every course (videos, articles, exercises), the video count accumulates naturally.
- Articles Count Too: A critical update in recent years: Reading articles counts toward the Tesla badge. This significantly speeds up the process, as reading is faster than watching.
- Playback Speed: Use the 1.5x or 2x playback speed feature. Since you only need to watch a few seconds for the "view" to register (usually ~10-15 seconds or a percentage of duration), you can cycle through playlists rapidly.
- The "Watch All" Trap: Do not just open tabs and let them play muted. The system tracks engagement. You must actively have the video player focused for the view to register reliably.
Feasibility: A highly dedicated user completing every single course on the site might hit 3,000 unique videos/articles. It is a badge for the true polymath who wants to learn everything Surprisingly effective..
4. Black Hole Badge: The Energy Point Singularity
The namesake Black Hole badge requires earning 10,000,000 (Ten Million) Energy Points.
Understanding Energy Point Economics
Energy points are awarded for almost every action:
- Watching a video: ~750–850 EP
- Completing an exercise (first time): ~150–500 EP (depending on difficulty)
- Mastering a skill (leveling up): ~500–1,500 EP
- Course Challenges: Massive bonuses (thousands of EP per session).
- Streaks & Daily Goals: Small bonuses.
The Grind Calculation
Let’s assume an optimistic average of 50,000 Energy Points per hour of highly efficient, focused work (heavy use of Course Challenges and mastery sprints).
- 10,000,000 / 50,000 = 200 hours of pure, optimal grinding.
On the flip side, efficiency drops over time. As you master skills, the "first time" bonuses disappear. Repeating exercises yields minimal points (often ~5–15 EP per problem). A more realistic long-term average for a regular user is 10,000–15,000 EP/hour That alone is useful..
