Various techniques to determine distance to objects in the universe are collectively known as the
A) Tully-Fischer relation.
B) Hubble tuning fork diagram.
C) distance ladder.
D) Eddington limit.

Question

Quizplus · Accepted Answer

The distance ladder is a series of methods used to determine distances to objects in the universe, each building on the accuracy of the previous method. This includes using parallax to measure distances to nearby stars, Cepheid variable stars to measure distances to galaxies, and supernovae to measure distances to even more distant galaxies. The Tully-Fisher relation and Hubble tuning fork diagram are specific methods within the distance ladder, and the Eddington limit is unrelated to distance measurement.
