Assigning a distance by redshift

Assigning a distance by redshift

Assigning a distance by redshift. The Hubble law lets us use a simple spectrum of a galaxy to figure out. where it is along the line-of-sight. Higher redshifts indeed go with smaller and fainter looking galaxies. Redshift takes us from 2-D to 3-D.

The Expanding Universe

The Expanding Universe

The Expanding Universe. Tuesday, January 15. Thomas Digges (16 th century) proposed an infinite universe. Infinite universe: hard to reconcile with appearance of the night sky. Night sky is dark , with stars (small in angular size) scattered across it.

ORIGIN OF THE UNIVERSE

ORIGIN OF THE UNIVERSE

ORIGIN OF THE UNIVERSE. Astronomers today believe the universe exploded (expanded) outward from a single point. This idea is known as the. Big Bang Theory. What evidence supports the Big Bang Theory?. the red shift in the spectral lines of distant galaxies.
