How does red shift of galaxies furthest from ours support the Big Bang Theory?
|
|
Edwin Hubble’s data of red shift
|
|
|
The wavelengths are getting longer
|
|
|
The universe is observed to be getting closer because of the res shift of galaxies
|
|
|
The universe is observed to be moving apart so it must have been closer together in the past. If we trace this expansion we would be able to locate the primordial atom.

Explanation:
Detailed explanation-1: -And here’s the relation between distance and redshift: the further away a galaxy is, the longer its light takes to reach us. A longer light travel time means more cosmic expansion, more wavelength stretching and thus a higher redshift.
Detailed explanation-2: -How does the red shift of distant galaxies support the big bang theory? According to the big bang theory, the universe is expanding. The expansion causes the galaxies to move away from each other. Red shift shows that the galaxies are moving away from each other.
