In one or two sentences make a hypothesis about the movement of a new galaxy and explain one way to test the hypothesis
Hypothesis: The new galaxy will exhibit a redshift in its spectrum indicating that it is moving away from us, and this can be tested by analyzing the galaxy's light spectrum using spectroscopy over an extended period of time to observe any changes in its spectral lines towards longer wavelengths.
Hypothesis: The new galaxy is likely moving away from our own galaxy due to the observed redshift in its spectrum, indicating that it is undergoing cosmic expansion.
Testing the hypothesis: One way to test this would be through the use of spectroscopy by determining the redshift of the galaxy's light spectrum, which can help establish its velocity and direction of movement in relation to our galaxy.
Hypothesis: The new galaxy is moving away from our own galaxy due to the expansion of the universe.
To test this hypothesis, one way is to observe the galaxy's redshift. By analyzing the light spectrum emitted by the galaxy, scientists can measure the extent to which the wavelengths of the light have been stretched, providing evidence of its motion away from us.
