Nuclear Fusion: what this star will be

Squeeze light atoms together hard enough and a little lost mass becomes sunlight.

By Constellate · 9 September 2026 · the short form

Nuclear Fusion is a star on the Constellate sky: placed by meaning, named, and connected to the stars around it. This is the short form of its post: the line it carries, the area we colour Physics, and what stands beside it today.

The line it carries on the sky: Squeeze light atoms together hard enough and a little lost mass becomes sunlight.

What stands beside it

The stars nearest to it are Black Holes, The Greenhouse Effect, Spectra as Fingerprints and Phase Transitions. When Nuclear Fusion opens, the conversation will land it among them, with a line drawn to each idea it touches.

Ask for this star

Every star is lit by demand. Ask for Nuclear Fusion and it moves up the list; when it opens, this post becomes the full essay. The open stars beside it can be walked today, and the first concept of every course is free.

On the map

A filled dot marks a star that is already open to walk.

Nuclear Fusion is not yet open to walk. Ask for it on the sky; the stars beside it are open, and the first concept of every course is free.
