\(\mathbf{T} / \mathbf{F}:\) Observers in a very distant galaxy would observe that galaxies far from them are more redshifted than are galaxies nearby.

Redshift is an important concept in astronomy that helps us understand the universe's expansion. When an object in space like a star or a galaxy moves away from us, the light it emits stretches. As the wavelength of this light increases, it shifts towards the red end of the spectrum. This change in wavelength due to the object moving away is what we call 'redshift'.

Redshift helps scientists measure how fast objects in the universe are moving away from each other. The greater the redshift, the faster the object is receding. This phenomenon is closely linked to the expanding nature of the universe.

The Doppler effect is what causes the redshift we observe. It is the change in frequency or wavelength of a wave concerning an observer who is moving relative to the wave source. You might be familiar with it in everyday life without realizing it.

Imagine a passing ambulance with a siren. As it approaches, the sound waves are compressed, making the siren sound higher in pitch. As it moves away, the sound waves stretch, lowering the pitch. This change in sound is the Doppler effect. For light waves, if a galaxy is moving away from us, the light it emits is stretched, causing a redshift. If it were moving towards us, we would see a 'blueshift' where the light shifts to the blue part of the spectrum.

One of the most mind-blowing discoveries in astronomy is that the universe is expanding. This means all galaxies are moving away from each other over time. Imagine the universe like a balloon; as you inflate it, every point on the surface moves away from every other point.

This expansion was first noted by Edwin Hubble in the 1920s. He observed that distant galaxies showed more redshift than those that were closer. From these observations, he formulated Hubble's Law, which states that the speed at which a galaxy moves away is proportional to its distance from us.

Therefore, if an observer in a distant galaxy looks in any direction, they will notice that galaxies farther from them exhibit a higher redshift than nearer ones. This universal principle shows that the farther away a galaxy is, the faster it seems to be moving away, confirming the continuous expansion of the universe.
