t seems that some researchers cannot get away from science fiction and its quest for the mastery of all of space. An article from Space.com entails a story of how we could use humanity’s quest with nuclear power and use it to say where our neighbours would we doing just the same thing.
“Humanity appears to be going down a dangerous path. We've developed weapons powerful enough to off ourselves many times over, for example, and we've been altering Earth's climate for decades without much regard for the serious consequences.”
“Similar behaviour may have led to the demise of advanced alien races around the galaxy, said Avi Loeb, the chair of Harvard's astronomy department.”
“So, the hunt for ET should be wide-ranging enough to spy artifacts left behind by vanished civilizations, he added — evidence such as burned-up planetary surfaces and products of nuclear war swirling in an alien world's air.”
“Avi Loeb co-authored a paper recently suggesting that 'Oumuamua, the first confirmed interstellar object ever spotted in our solar system, might be an alien spacecraft.
The consensus view is that 'Oumuamua is a cometary body. But it's important not to dismiss the spacecraft idea out of hand, Loeb stressed.”
