Primes¶
- Absence as Information
- Spectral absorption lines in astrophysics are the formal worked instance, because the absence is literally a missing photon read as a positive signal.
This sourceEstablishes that absorption lines — flux missing at specific wavelengths — fingerprint the composition of an intervening medium.
SupportedVerified against the work's full text
Kirchhoff and Bunsen show the Sun's dark lines are a reversed gas spectrum, so finding which substances match them is a chemical analysis of the solar atmosphere.
“Hiernach erfordert die chemische Analyse der Sonnenatmosph ¨are nur die Aufsuchung derjenigen Stoffe, die, in eine Flamme gebracht, helle Linien hervortreten lassen, die mit den dunkeln Linien des Sonnenspectrums coincidiren.”

Verification¶
Does it exist? Confirmed. This work's DOI resolves to a registered record, which fixes its identity. That is all it fixes.
Does it back the claim? Read against the text for 1 of 1 citation: 1 supported. Each verdict is shown under its citation below, with what in the work backs the sentence.
Support is checked per citation rather than per work — the same source can be cited soundly in one article and wrongly in another. Per-citation recording began recently, so a citation with no recorded check is a gap in the record rather than evidence it went unchecked.
