The #FermiParadox revisited: #Technosignatures and the #ContactEra - A new #solution to the Fermi Paradox is presented: probes or visits from putative #aliencivilizations have a very low probability until a civilization reaches a certain age (called the Contact Era) after the onset of #radiocommunications.
Yesterday, I realized that I needed to know how my alien species writes their numbers. I already know they write from bottom up (right to left when describing the past, left to right when describing the future). They also use base-6 for counting.
I'm happy with the system I came up with. This is how they write the year 21515, or 2999 in base-10.
I'm exploring the justice system of one of my alien civilizations. They pride themselves on being a peaceful advanced society (50-100 years ahead of humanity). One of their core creeds roughly translates to "there are no killers in a civilization". Yet they do apply the death penalty in rare cases of murder. And their police are also judge and executioner. How do they square this, and how did it evolve?
