Why does the red shift of galaxies provide evidence that the universe is expanding?
It means that the light from galaxies is losing energy. The only reasonable explanation for this is the cosmoligical redshift - that is, that the Universe is expanding.
Is space travel to other galaxies possible?
Not with present human technologies.
What is the red shift of light from most galaxies is evidence that?
The most plausible explanation for the redshift is that galaxies are moving away from us. This is similar to the Doppler effect, but it is normally believed that space itself is expanding, so the situation is a bit different from the "normal" Doppler effect.
What are reasons for space travel?
to explore many different planets, galaxies, comets, possible planets we can live on, etc.
What is the possessive form of galaxies?
The possessive form for the plural noun galaxies is galaxies'.Example: Their galaxies' paths do not coordinate.
A possible explanation of an observation?
The possible explanation of an observation is a hypothesis.
A possible explanation for how or why something happens is called what?
A possible explanation is called a hypothesis.
Is it possible for there to be unknown colors in other galaxies?
no.

Who said Those who believe no explanation is necessary those who do not believe no explanation is possible?
"To one who has faith, no explanation is necessary. To one without faith, no explanation is possible." ― St. Thomas Aquinas
What type of galaxy is the dimmest?
There are galaxies that orbit our galaxy that are believed to be filled with a lot of dark matter. Segue 1 is one of about two dozen dwarf galaxies around ours that have light outputs equal to only a few hundred times that of our sun. There are probably untold numbers of other such galaxies around the more visible galaxies. This is a possible explanation for the discrepancy in the predicted mass of the universe and the observed mass. Some theories postulate that 90% of the mass of the universe is composed of this unobservable "dark matter". The existence of these dim dwarf galaxies help explain the discrepancy.
How many galaxies are in the local cluster?
Around 42 named galaxies, with 13 possible additions. See related question.
Where can one find information on tornado formations?
Surprisingly, the Wikipedia page titled "Tornadogenesis" offers a good explanation of how tornadoes form.
How does light from distant galaxy . galaxy out side of 32000000 light years support the big bang theory?
The light from distant galaxies is redshifted. The only reasonable explanation for that is that the galaxies are moving away from us.
What is a possible explanation to a question?
A hypothesis.
