Re: Ancient Aliens

Civilizations don't need FTL, they can exchange speed for time however....spacecraft traveling at half the speed of light or .9c can go a long way if the civilization is I thousands or millions of years older than ours....however, they can do better...Von Neuman machines...self replicating and scattered throughout the galaxy can do the job in on a shorter time. They could spreads themselves with copies made from stored DNA or beam themselves as information in lasers. Question is can we even detect von neuman machines?
