-
A.
Lemaître–Hubble law
chosen
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.
-
B.
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.
-
C.
A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae
"A Relation between Distance and Radial Velocity among Extra-Galactic Nebulae" is Edwin Hubble’s landmark 1929 paper that established the linear relationship between galaxies’ distances and their recessional velocities, providing the first strong evidence for the expanding universe.
-
D.
Faber–Jackson relation
The Faber–Jackson relation is an empirical correlation in astronomy that links the luminosity of an elliptical galaxy to the velocity dispersion of its stars, providing a key tool for estimating galactic distances and masses.
-
E.
Lambda-CDM model
The Lambda-CDM model is the standard cosmological framework describing a universe dominated by dark energy (Λ) and cold dark matter (CDM), successfully explaining the large-scale structure, expansion history, and cosmic microwave background observations.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
