Target entity: cosmic distance ladder Context triple: [Leavitt law, isPartOf, cosmic distance ladder]
-
A.
Tully-Fisher relation distances
Tully-Fisher relation distances are galaxy distance measurements derived from the empirical correlation between a spiral galaxy’s luminosity and its rotational velocity.
-
B.
“A New Method of Determining Distances to Galaxies”
“A New Method of Determining Distances to Galaxies” is a scientific paper that presents an innovative technique for measuring the distances to external galaxies, contributing to more accurate extragalactic distance scaling in astronomy.
-
C.
The Expanding Universe
"The Expanding Universe" is a chapter in Stephen Hawking’s popular science book *A Brief History of Time* that explains how observations and cosmological theory reveal that the universe is growing larger over time.
-
D.
Lemaître–Hubble law
The Lemaître–Hubble law is the fundamental cosmological relation that expresses the proportionality between a galaxy’s recessional velocity and its distance, providing the first observational evidence for the expansion of the universe.
-
E.
observable universe
The observable universe is the portion of the entire cosmos that we can in principle detect or observe from Earth, limited by the finite speed of light and the age of the universe.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
