A star, alive.

An evolving surface. Luminous plasma. A moment suspended above the Sun.

Voice & atmosphere

Your recorded voices. Original speaking speed. A separate journey timing for each language.

Additional lesson recordings

New English/Hebrew lesson voices use hosted recordings unless embedded or imported. For offline playback, import table-en.wav, table-he.wav, orbit-en.wav and orbit-he.wav, or use the ZIP’s download-and-build script.

All 15 chapters include recorded narration in English and Hebrew. Original captions follow measured sentence timings. The two interactive side-wall lessons add recorded English/Hebrew explanations, with subtitles following the active voice. Added voices stream online unless embedded or imported.

Sun → Earth retains your two-minute score. The longer Sun-to-Earth passage crossfades the existing score when needed. Added side-wall explanations are visual, not newly recorded narration. The lunar chapter reuses a quiet passage of the existing ambience as its music bed, alongside your new chapter recordings. Music dips under the voice. The soundtrack is artistic, not sound recorded travelling through space.

Caption delay 0.00 s

Replace a narration chapter (optional)

All four Sun-to-Earth chapters are included in English and Hebrew. Optional replacements: 06-star-en.wav, 07-planet-en.wav, 08-distance-en.wav, 09-home-en.wav; use he for Hebrew. All six Moon chapter recordings are now included in English and Hebrew. Optional replacements still accept 10-descent-en.wav, 11-observatory-en.wav, 12-aim-en.wav, 13-optics-en.wav, 14-neighbour-en.wav, 15-read-en.wav (or he). Packaged captions have per-recording sentence timing. Replacement imports stay in this tab and require new alignment.

Changing narration language pauses at the current chapter’s beginning. Scrubbing is silent while you drag; releasing continues only when the journey was already playing. Chapter selection follows the same play/pause state. Clicks and taps do not pause playback. Dragging or scrolling pauses the guided explanation; Resume journey or Space gently returns to the saved view and continues from the same moment. Subtitles stay visible when controls are hidden.

Replay resets the report. Measure on the room computer; exported timings are frame intervals, not isolated GPU timings.

Axial rotation is accelerated independently for visibility; the side-wall orbit diagram is a simplified, time-compressed teaching model, not an ephemeris. Artistic, enlarged and time-compressed solar visualization; not a physical fluid simulation. The new observatory and lunar relief are original illustrative assets, not surveyed geography. Earth surface: NASA Blue Marble via Basemap; procedural clouds are illustrative, not current weather. Body sizes and distances are not shown to scale. Golden colors and simultaneous atmosphere visibility are a composite treatment. Room output is one flat panorama; physical wall-angle calibration and projector warping are not included in this prototype.
