Squeeze light nuclei hard enough and they merge, releasing energy from lost mass via E = mc squared. Fusion powers every star in the sky - and explains why making it work on Earth is so stubbornly hard. This is the real knowscape from knowhere, not a picture of one. Drag it. Watch what actually changes.
The nucleus is heavier than its parts should allow — except it isn't, because the missing mass left as binding energy when the thing formed. Fusion is just this run in reverse: fuse light nuclei, land somewhere more tightly bound, and the mass deficit ships out as E=mc². That's what a star burns.
Runners wait in line, no baton passed along the track yet.
Each sprints in fast enough to complete the handover to the next.
The whole chain fires through, releasing a surge with every pass.
This concept has no prerequisites in knowhere's map — it is a root. Everything in the topic is built from here.
Each one is its own knowscape in the app — built for how a particular student takes things in, not one explanation handed to everybody.
Every HSC and VCE concept in knowhere is built like this one — mapped to your curriculum, never capped by it. Free for a week. No card tricks, no lecture.
Free for a week, then $49 once — the 2026 exam pass ends itself after the last exam. 0 days of the pass left.
Free for a week, then a plan you can stop any time.
