The red-shift in the spectral lines of light, reaching us from other galaxies implies that these galaxies ____
|
|
Are moving closer to one another
|
|
|
Are moving farther apart from one another
|
|
|
Are in rapid rotation
|
|
|
Redshift doesn´t exist
|
Explanation:
Detailed explanation-1: -The red shift occurs due to increase due to increase in wavelength that would be due to the increasing distance between two galaxies, Red shift indicate that galaxy are mainly farther apart from one another.
Detailed explanation-2: -Bottom line: A redshift reveals how an object in space (star/planet/galaxy) is moving compared to us. It lets astronomers measure a distance for the most distant (and therefore oldest) objects in our universe.
