There are millions of habitable planets in our milky way. Approximately four of them have hostile alien civilizations that could attack Earth, suggests new research by Alberto Caballero — a doctoral student in conflict resolution at the University of Vigo in Spain.
In his paper, Caballero asked: What are the odds that humans could one day contact a hostile alien civilization capable of invading our planet?
This is the basically ‘thinking past the sale’, like the people who just assume that sea levels are rising and put all their effort into figuring out what the results will be.
