Kb minden tavoli dolog tavolsagat, stb a "standard gyertyakbol" (+voroseltolodas, stb) vezetnek le. Feltetelezik azok standardok, allandok mindenhol a vilagegyetemben. De ha ez feltetelezes megsem jo, akkor kb minden eddigi "meres" hamis.

A significant issue with standard candles is the recurring question of how standard they are. For example, all observations seem to indicate that Type Ia supernovae that are of known distance have the same brightness (corrected by the shape of the light curve). The basis for this closeness in brightness is discussed below; however, the possibility exists that the distant Type Ia supernovae have different properties than nearby Type Ia supernovae.
