Question
Cosmologists measure both “comoving” and “proper” forms of this quantity. A method for calculating this quantity divides 1 by the angle of the difference in position after measurements taken six months apart. As part of this quantity’s “cosmic ladder,” objects with known (*) luminosities called standard candles serve as indicators of it. Recessional velocity is proportional to this quantity for galaxies by Hubble’s law. This quantity is measured in parsecs, astronomical units, and light years. For 10 points, name this quantity that measures how far apart two objects in space are. ■END■
ANSWER: distance [or length; accept descriptions like “distance from Earth” or “distance away”; accept comoving distance or proper distance; accept distance modulus; accept cosmic distance ladder]
