Why scientist don't expect to find galaxies that have large blue shifts because of the big bang theory?
The observations show that the Universe is expanding. The farther a galaxy is away from us, the faster it moves away from us. Galaxies also have individual velocities, compared to their "local space", but those tend to be slow (in the order a few hundred kilometers per second), and at greater distances, the general expansion of the Universe dominates.
Large Doppler shifts indicate?
Large Doppler shifts indicate significant changes in the frequency or wavelength of light or sound waves due to the relative motion between the source and the observer. If the shift is towards shorter wavelengths (blue shift), it suggests that the source is moving closer, while a shift towards longer wavelengths (red shift) indicates the source is moving away. In astronomy, large red shifts are often associated with distant galaxies, providing evidence for the expansion of the universe.
How do galaxies very?
For example, galaxies are very large, very massive, very bright, and (most of them) very far away from us.
Do galaxies at very large distances look distorted?
Yes, galaxies at very large distances can appear distorted due to gravitational lensing effects caused by the bending of light by massive objects. This distortion can elongate or warp the images of distant galaxies, altering their perceived shapes.
What is a large group of gas dust and millions of stars?
That can be a large globular cluster, or a galaxy. Or any larger structure that includes galaxies.
Are Large red shifts within galaxies or between them?
Between them.
Why scientist don't expect to find galaxies that have large blue shift?
This should be because of the fact that the Universe is expanding. You see a blueshift when objects move closer to you. Other than super distant galaxies, most galaxies will not measure to be a blueshift due to the fact that the Universe is expanding and accelerating.

Which of these galaxies would you most likely find at the center of a large cluster of galaxies?
At the center of a large cluster, you'll usually find large and massive galaxies.
What is one way that an elliptical galaxy differs from the other types of galaxies?
Elliptical galaxies are large blob shaped galaxies that most galaxies will eventually look like. Elliptical galaxies are what happens when two or more large galaxies collide and coalesce.
When do scientist use light-years?
That is usually measured for large distances, such as the distance to other stars, or even to other galaxies. Another unit, the "parsec", is also common in this case.

How does the galaxy get bigger?
Galaxies get bigger by a process of merging. The gravitational attraction of the galaxy and the dark matter round it pull in satellite galaxies and these merge with the main galaxy. Eventually large galaxies merge to form large elliptical galaxies. look at the link below.
Do dozens of dwarf galaxies merge and form into a giant elliptical galaxy?
Not just dwarf galaxies. Giant elliptical galaxies lie likely the result of many galaxies, small and large, merging.
What are two categories of the size of galaxies?
Large and Dwarf.
What is the estimated number of large galaxies since there are 100 billion galaxies in the universe?
If you counted 1 galaxy per second, it would take ~3200 years to count all 100 billion galaxies in the universe.
What are the names of some irregular galaxies?
Canis Major Dwarf and Small Magellanic Cloud are irregular satellite galaxies of the Milky Way.The two irregular galaxies that orbit the Milky Way are the Large and Small Magellanic Clouds.
