The intensities of peaks show that galaxies are moving toward each other.
The red shift shows that galaxies are moving toward each other.
The red shift shows that galaxies are moving toward each other.
The red shift shows that galaxies are moving away from each other.
The correct answer is: The red shift shows that galaxies are moving away from each other.
The correct answer is: The red shift shows that galaxies are moving away from each other.
Spectroscopy provides evidence for the Big Bang theory through the observation of the red shift in the light emitted by galaxies. When light from distant galaxies is analyzed using spectroscopy, scientists can observe a shift in the wavelength of the light towards longer wavelengths, which corresponds to a shift towards the red end of the spectrum. This phenomenon is known as red shift.
The red shift in the light spectrum of galaxies indicates that they are moving away from us. This observation is consistent with the idea that the universe is expanding, as predicted by the Big Bang theory. The greater the red shift observed, the faster the galaxy is moving away from us, providing further evidence for the expansion of the universe.
Therefore, spectroscopy and the observation of red shift provide evidence for the Big Bang theory by showing that galaxies are moving away from each other.
