How can an extinct space civilization save humanity?
Avi Loeb, head of the astronomy department at Harvard University, said: "Similar behavior may have led to the demise of advanced geospatial civilizations and species around the galaxy." In fact, this may at least help explain why we are not connected to any space civilization; despite the abundance of habitable places in the Milky Way (a mystery known as the Fermi paradox).
"One possibility is that these civilizations have followed the same approach as we do today, they were short-lived," Loeb said last week at the Humans to Mars summit in Washington. "They thought superficially, and they made wounds for themselves that killed them later," he said.
Therefore, the search for a space civilization must be large enough to investigate any signs or signs left by the civilizations that have disappeared, as well as clear evidence such as the burned surfaces of planets, and the consequences of nuclear wars in the air of these worlds of space.
This discovery may be the greatest scientific discovery of all, and may have the added benefit of placing the problematic races of our planet on the right path.
"The idea is that we might learn something from this process. We may learn to act better with each other, not to launch a nuclear war, or to observe our planet and make sure it is livable as long as we can make it viable. "
"There are other practical justifications for looking for a smart space civilization like SETI," he says. "This can lead to a major development in technology; if the satellites are good enough to exchange their knowledge."
"Our technology is only a century old, but if there are other civilizations that spent billions of years developing travel through space, they might teach us how to do it."
This is another reason to continue to push for the development of space travel technology, he added. Loeb is involved in this field; chairs the advisory board for Breakthrough Starshot, a $ 100 million project to develop probes-powered laser-sailing or laser-sailing systems that can capture systems of extrasolar planets and amplify them by 20 percent % Of light speed.
The Breakthrough Starshot application is intended to run this system in 30 years or so. "If this attempt succeeds, intelligent space objects may look at us from a new perspective, as close peers deserve attention and respect," Loeb said.
"I hope that finding dead civilizations will inspire us to act better and work together," he said. Another hope is that once we get out of the solar system, we will receive a message: Welcome to the Interstellar Club. "We will discover that there is a great traffic movement that we were not aware of."
"We may have already hinted at this movement," Loeb said. Lopez recently co-authored a scientific paper suggesting that Oumuamua, the first interstellar object ever seen in our solar system, is likely to be a strange spacecraft. The agreed view is that Umumawa is guilty; but it is important not to rule out the idea of a spacecraft.
"We have to remain open and not assume we know the answer in advance," he said. "I do not need to pretend you know anything."
