The stars within this zone are four to eight billion years old, making 75% of them older than our own five billion year old sun. Dr. Charles Lineweaver of the University of New South Wales puts this into perspective:
“75% of the potential alien invaders have a one billion year evolutionary head start on us, and half of them have a two billion year head start. To put that in perspective, it only took us 500 million years to evolve from worms into humans. This clearly means that any potential alien threats are far more highly evolved than we are, perhaps having acid for blood and the ability to gestate within the gastrointestinal tracts of other species. Also, they would have developed vastly higher technology than humans, which makes it unlikely that they would spare us for use as slaves.”
“The other major take-home fact is that their sun is going to burn out much sooner than ours, making them greedy for interstellar conquest so to move their doomed race to a new homeworld.”
“We’re currently broadcasting a beacon signal of interstellar goodwill, in hopes that we might soon hear from our noble brothers in space. I’m sure that once they get to know us, they will respect us in much the way we respect less evoloved species.”
