1. As time past, the accelerated expansion of Universe will make to see less and less galaxies, or because we can see further, we will see more and more galaxies? 2. Considering a constant expansion (not accelerated) at today value (70.8 (km/s)/Mpc), how far is the most distant galaxy to witch we can send a radio message? How far it will be that galaxy when the message will arrive? Thank you for any answer. I will appreciate if somebody will show me the equations used to calculate the values for second question.
