A new study wants to change the way we understand the possibility of the existence of extraterrestrial life , urging that they not only accept that we are not alone in the universe, but many other civilizations came into existence, only they’d be extinct.
This theory is proposed by a study led by Adam Frank, professor of physics and astronomy at the University of Rochester in the United States, along with Woodruff Sullivan, part of astronomy and astrobiology program at the University of Washington. The idea is based on the Drake equation that manages the SETI and other search for extraterrestrial organisms, posing another way of understanding necessary for a technological civilization reaches contact us variables. extinct extraterrestrial civilizations
Frank and Sullivan say that although we know approximately how many stars there (and that a fifth of these stars have planets, or exoplanets in habitable zones) we do not know is how many of those planets might have already experienced its own evolution of life up the development of intelligent life, and that by now extinct.
Its formula ensures that the probability that we are human we are the only advanced life form that has existed in the universe is “one 10 quadrillion”, which is a really low probability. extinct extraterrestrial civilizations
The universe has an age of more than 13,000 million years, while our civilization takes only 10,000 years exist. Is it not possible that many have come before us, in different corners of the galaxy? Enough, and that’s what we want to prove this theory. extinct extraterrestrial civilizations
And in fact, the formula proposed by Frank and Sullivan is much simpler, at least in theory, to ensure that due to the age of the universe and the amount of time that our civilization has been part of it most likely is that many civilizations they existed before us, even in our beloved Milky Way.
