Why distant galaxies are traveling away from us at great speeds?

This is because the universe is expanding - only the Milky Way and the Andromeda Galaxy are heading toward each other, and they will eventually collide.
This is sometimes referred to as "The Big Bang Theory".

What is The bending of light due to the great mass of distant galaxies?
The bending of light due to great masses is called Gravitational MicroLensing.
What are distant galaxies with black holes in their centers called?
There have been some suggestions that the objects called quasars might be extremely active galaxies with unusually supermassive black holes at their centers at such great distance from us that it is not possible for telescopes to resolve their galactic structure, making them just look like very bright stars (quasi-stellar objects). However this has not been verified.If these suggestions are correct, these extremely active galaxies must be so distant that the light we are seeing from them must have been emitted only a short time after the big bang began, in the initial cycle of star formation, which would make them the earliest galaxies formed and likely very young galaxies. However if they are this young these extremely active galaxies might have galactic structures so different from the galaxies we are familiar with that even if our telescopes could resolve them, we might not recognize them as galaxies.
Why can rock avalanches move a such great speeds?
Gravity speeds them up.
What is the largest known structure in the universe and is composed of galaxies and clusters of galaxies?
A so-called "great wall", which is a block of galaxies more than a billion light-years long.
Name 2 distant places from where you can see the Great Pyramid?
Space (very distant) and the Valley of the Kings
Why do astronomers theorize that most of the matter in galaxies and clusters of galaxies is dark matter?
most of the mass in a cluster of galaxies is invisible, which provides astronomers with the strongest evidence that the universe contains a great amount of DARK MATTER

Which galaxies have a great many short spiral segments branching from the spiral arms?
This may refer to the so-called "flocculent galaxies". Perhaps it's the "multiple arm galaxies", which are sometimes put in with the flocculent type.
Where are two distant places the Great Pyramid can be seen from?
moon
Do all the galaxies form a bigger galaxy?
Over time - billions of years - galaxies will merge with other galaxies. In about 3 billion years, the Andromeda galaxy will merge with our own galaxy, the Milky Way.However, the separation between galaxies is so great, that not all galaxies will merge unless the fundamental issue of the amount of mass in the Universe is determined.If we live in a "contracting universe" then eventually all galaxies will merge.

Where can you find information on the Big Bang theory?
There is a lot to know. Go here: http://en.wikipedia.org/wiki/Big_Bang_Theory The Big Bang Theory is the dominant scientific theory about the origin of the universe. According to the big bang, the universe was created sometime between 10 billion and 20 billion years ago from a cosmic explosion that hurled matter and in all directions. In 1927, the Belgian priest Georges Lema�tre was the first to propose that the universe began with the explosion of a primeval atom. His proposal came after observing the red shift in distant nebulas by astronomers to a model of the universe based on relativity. Years later, Edwin Hubble found experimental evidence to help justify Lema�tre's theory. He found that distant galaxies in every direction are going away from us with speeds proportional to their distance. The big bang was initially suggested because it explains why distant galaxies are traveling away from us at great speeds. The theory also predicts the existence of cosmic background radiation (the glow left over from the explosion itself). The Big Bang Theory received its strongest confirmation when this radiation was discovered in 1964 by Arno Penzias and Robert Wilson, who later won the Nobel Prize for this discovery. Although the Big Bang Theory is widely accepted, it probably will never be proved; consequentially, leaving a number of tough, unanswered questions. The Big Bang Theory does not necessarily go against those who belive in Creation. God could have very well used the Big Bang to create the universe.
