[Zero Signal]

As far as the galaxies being frozen in time, I am going to paraphrase what I read regarding it.

All of the distant galaxies are moving away from us, and at an accelerated rate. At this rate of acceleration, they will eventually begin receding at the speed of light, making it impossible for their light to be observed by us. In effect, the light cannot keep up with the Universe's rate of expansion. Intelligent life in galaxies with redshift of, I believe, 2 or more would not be able to send a signal to us because of this accelerated expansion.

The term "event horizon" is used also in this case to describe the point at which no further light can be received, as it is used in relation to black holes. 50 to 100 billion years is the calculated time frame, with those galaxies local to us and in out particular cluster will not be affected in our frame of reference. Then the light from the galaxies outside of our Local Group will evenutally fade away, as well.
