Cinematic Black Hole Visuals
60.00%Short reels showcasing AI-rendered or CGI black holes with vivid color accents (fire-red, pink, gold, blue). These posts lean on visual spectacle and drive the highest raw like counts. The color variation across posts keeps the feed fresh while the core subject stays consistent.

Strategy summary
What's working, what to fix, and what to ship next.
TL;DR
Post 21 is the clearest signal in this dataset, pulling 35,354 likes on a standard black hole reel, more than 4x the next best performer (post 5 at 8,617 likes). The gap is not explained by format alone since both are reels with similar subject matter. What separates the top tier (posts 5, 6, 11, 15, 17, 21) from the mid and bottom tiers is copy quality and emotional framing. The bottom 20% of posts average under 300 likes and all share one trait: they are hashtag-only captions with zero narrative hook.
The account posts 2.3 times per week, well below the 5-per-week benchmark for this niche, which limits algorithmic reach. Color-variant black hole reels (fire-red, pink, gold) consistently outperform neutral or monochrome versions. The sci-fi scenario format used in posts 13 and 14 generates above-average comment engagement relative to likes, suggesting it drives genuine conversation rather than passive scrolling.
The single biggest leak is the hashtag-only post format. Posts 8, 16, 18, 23, and 26 all fall below 1,200 likes despite sitting in the same feed as posts hitting 5,000 to 35,000. Retiring that format and replacing it with even a two-sentence hook would lift the floor meaningfully.
Working
4- Color-themed black hole reels (fire, pink, gold) consistently land in the 2,500 to 8,600 like range and should be the content backbone.
- Narrative sci-fi framing like the beach and sun-replacement scenarios in posts 13 and 14 drives higher comment rates than pure visual posts.
- The 'Witness [phenomenon] + physics payoff' hook structure used in posts 17 and 22 generates strong saves-style engagement.
- Posting on Monday and Thursday aligns with the highest-performing dates in this window (posts 5, 15, 17, 21).
Risks
4- Hashtag-only captions (posts 8, 16, 18, 23, 26) average under 1,100 likes and should be retired immediately.
- Posting cadence at 2.3 per week is too low for this niche. Reaching 5 per week would significantly expand algorithmic distribution.
- Color repetition within the same week (two purple posts on 07-18 and 07-23) dilutes novelty and likely split the audience, post 10 got only 88 likes.
- The 'Follow for daily' CTA is truncated in most captions, suggesting copy is being cut off and the full hook never lands.
Ship next
5- Retire all hashtag-only captions and write a minimum two-sentence hook for every post starting this week.
- Build a 7-day color calendar so no color variant repeats within a 5-day window.
- Test one sci-fi scenario reel per week (beach, cityscape, sunrise) to expand the scenario pillar beyond 13% of feed.
- Increase cadence to 5 posts per week by repurposing top performers (posts 5, 21) into carousel explainer formats.
- Add a clear CTA question to high-performing visual posts, such as 'Which color would you choose?' to drive comment volume toward the 50-plus threshold that triggers wider distribution.
