Does Failing to Detect Aliens Mean We’ll Never Be Contacted?

Dr. Grimaldi’s results provide statistical assessments on when a radio signal might pass by the Earth, which he refers to as a “crossing event”, noting a 95% probability the next crossing event will not occur longer than 100,000 years, 50% probability of a crossing event occurring between no less than 60 to 1,800 years, and 20% probability of a crossing event occurring no sooner than 240 years.

“In the ‘silent bubble’ scenario, the waiting time of no less than 60 years is very optimistic,” Dr. Grimaldi recently told. “Moreover, even after this time span, the fact that the Earth may be illuminated by technological signals is a necessary but not sufficient condition for their detection since they may be missed by our telescopes. Thus, even in the optimistic 60-year time window for a crossing event, the waiting time until detection could be much longer.

Given the study’s results provide a wide range of probabilities for detecting a technosignature in the future, and since the study focuses solely on technosignature searches conducted by SETI, what steps can be taken if we were to “rethink current search strategies”, as noted in the paper, regarding how SETI conducts its searches?

“If it is true that it could be several years, if not centuries, before a technosignal is potentially detectable, then it may be better to focus on commensal SETI investigations, i.e., searching for technosignals from data collected by telescopes performing other observational activities, rather than investing resources and telescope time in active SETI searches,” Dr.

“I like to think that we are not alone, in the sense that other life forms, not necessarily advanced, could populate the universe,” Dr. Grimaldi recently told. “Complex or even technological life may be much rarer than was thought decades ago, but its existence is not precluded by the physical laws we know. To the question of whether we will ever be able to detect them, I have no answer.”

ET_Exists No ! Not at all. Just a matter of time. We are NOT alone in the universe, and even ( maybe or possibly ) in our own solar system and galaxy.

ET_Exists I was arrested by Kipping's bon mot, were we inhabitants of a superearth we mightn't ever garner the wherewithal to escape our very own gravity well.

ET_Exists Such failure is always mutual.

ET_Exists Yes

ET_Exists humans have a long way to go before we are worth contacting :( they would take 1 look and drive on by :)
