Recently released and formerly secret United States files revealed that the Department of Defense (DOD) has investigated the best possible path to get in touch with aliens and speak with a possible 4,590 extraterrestrial civilizations.
The Defense Intelligence Agency (DIA) document, which was acquired by the Sun as part of a huge Freedom of Information request, is a scientific research into SETI, which is an acronym for Search for Extraterrestrial Intelligence.
The report, which was sanctioned by the U.S. government, said its goal is to “ascertain whether alien civilizations exist in the universe, how far from us they exist and possibly how much more advanced than us they may be.”
“As of 2009, the only physical tools we know that could help us get in touch with aliens are the electromagnetic waves an alien civilization could emit and we could detect,” the report added.
However, with the current technology, the government cannot explore for aliens “beyond a few hundred light-years away.” It also said that in the past 50 years of SETI searches, no extra-terrestrial civilization was found because “quite simply we did not get far enough.”
Contact with aliens “demands the construction of much more powerful and radically new radio telescopes,” which the files said were being planned and should have been finished around 2020.
The report focused on how distant alien civilizations are and how long it will take humans to arrive there.
It assumed that there could be 4,590 extraterrestrial communities in the universe and the distance of the closest one is probably between 1,933 and 2,670 light-years away in accordance with advanced calculations from the former and current.
