Space spreads out infinitely in all directions. Furthermore, galaxies fill all of the space through-out the entire infinite universe. But there are few boundaries exist, due to the age of the universe and the speed of light. The particle horizon is the maximum distance from which light from particles could have traveled to the observer in the age of the universe. The Cosmological event horizon is the measure of the distance from which one could possibly retrieve information.
