Imagine what will happen when, as all the scientists here know to be the strict nature of Relativity, it turns out there is nothing to disclose? Nothing will happen. Nothing will change. This alien nonsense will titillate new generations for another 60 years until another blue ribbon commission is impaneled and reports that there really isn't anything there. And the cycle will repeat until we extinguish ourselves in our own filth when the community of aliens could have saved us but refused because, as a species, we're too fuckin' stupid.
