About
우리는 온도가 내려갈수록 물질을 이루는 원자와 분자의 움직임도 점점 줄어든다고 배웁니다. 그렇다면 계속 냉각하다 보면 언젠가는 모든 움직임이 완전히 멈추는 순간에 도달할 수 있을까요? 과학에서 그 극한의 온도를 절대영도, 0켈빈(K), 영하 273.15°C라고 부릅니다. 그런데 놀랍게도 과학자들은 절대영도에 가까이 다가갈 수는 있어도 정확히 그 온도에 도달할 수는 없습니다. 이 영상에서는 온도가 실제로 무엇을 의미하는지부터 시작해, 왜 온도가 낮아질수록 냉각이 어려워지는지 살펴봅니다. 또한 열역학 제3법칙, 엔트로피, 극저온 물리학, 레이저 냉각, 보스-아인슈타인…

Frequently asked questions
How accurate are these YouTube video analytics?
View, like, and comment counts come from YouTube's public API and refresh regularly. Growth and revenue figures are estimates built from tracked historical data, so they can differ slightly from what the creator sees privately in YouTube Studio.
What is the outlier score?
How this video's views compare to the channel's usual Shorts or long-form video. A 2x score means double the usual views for that channel, 0.5x means half.
What is engagement rate and how is it calculated?
Likes and comments per view, compared to this channel's typical engagement rate — shown as above or below what's usual for the channel.
How is the revenue estimate calculated?
It's a rough public estimate based on a $0.7–$2.0 CPM (revenue per 1,000 views) applied to view count — not actual creator earnings, which depend on ad rates, audience geography, and monetization settings YouTube doesn't expose publicly.
Is this YouTube video analytics checker free?
Yes. You get 10 free channel and video analytics lookups per rolling hour without an account — logging in, which is also free, removes that limit entirely.
