How is it possible that the universe could have existed for an infinite amount of time in the same state if galaxies are continuously receding from each other?
The universe has not existed in the same state for an infinite amount of time, that would be the steady state theory, which has been replaced by the big bang theory. The galaxies are moving away from each other because the universe is expanding at an increasing rate. It has been expanding since the big bang happened 13.7 billion years ago.
How is it possible that the universe could have existed for an infinite amount of time if the galaxies are constantly receding from each other?
According to prevailing theories the universe has not existed for an infinite amount of time but is approximately fourteen billion years old.
How does the energy of the cosmic microwave background compare to the energy radiated by all the stars and galaxies that ever existed?
The energy of the cosmic microwave background is about 400,000 times less than the energy of all the stars and galaxies that ever existed. The CMB is the remnant radiation from the early universe, while the energy radiated by stars and galaxies have been accumulating over millions of years.
Is the universe the creation of matter or the expansion of matter which is pre existing?
The matter that existed since the Big Bang is expanding. A few decades ago, a "steady-state" theory was popular; according to it, matter was created as the Universe expanded, thus maintaining the matter density in the Universe constant. However, observational evidence did not support this theory.The matter that existed since the Big Bang is expanding.
