As time passes, it is critical to recognize that the urge to confirm that we are not alone in the cosmos is more than ever. We need to know if we are alone or not so that we can prepare for an encounter or our fate.
If it is established that humanity is the only civilization out there, it is bad news for us because there must have been other civilizations out there, but being the only one left means that we will also fade into obscurity sooner rather than later.
Using a cosmic scale that takes into account humanity’s own evolution, Christopher Conselice devised a revolutionary new approach known as the “Copernicus Astrobiological Limit,” which would result in determining how many possible civilizations exist out there.
Copernicus’ two Astrobiological Limits demonstrated that life could reach our level in less than 5 billion years and that 36 active civilizations might do so in our galaxy.
However, because each civilization is around 17,000 light-years apart, going from one location to another would most certainly result in a very long period of time.
Seeing them as extinct would demonstrate that our own timelines end abruptly, but discovering them alive would indicate that we have a chance of outliving our own expectations.
