Billions of alien civilizations have existed

Seek out alien civilization or the interest in capturing aliens that are very popular. Scientists calculate and almost certainly many extraterrestrial civilizations have existed in this universe.

Last May, astronomers Adam Frank of Rochester University and Woody Sullivan of the University of Washington adjusted the equation Drake (a mathematical formula proposed by astronomer Frank Drake, for the purpose of estimating numbers. galactic civilization) famous for calculating how diverse the universe is.

The result of complicated calculations shows that alien civilization has continuously grown in parts of the universe over its 13.8 billion years of history.

Tech Times on June 16 reiterated Frank's comment in the New York Times editorial, in which Frank made arguments about the existence of aliens and said now there is quite a bit of information. making them "almost certainly (alien civilization) exist".

Thanks to new data from NASA's modern Kepler telescope, scientists were able to change the equation Frank Drake proposed in 1961 and calculate more accurately. In addition, instead of investigating how many civilizations exist, they question the earthly life like Earth - the advanced technological civilization - whether or not it existed.

How to put this issue to help them handle 3 unknown factors well: probability of creator of life, intelligent life and technological capacity.

They found that the ratio of non-extraterrestrial life was extremely low, only about 1 in 1,000 billion opportunities. That means life on Earth is not the first and last technological civilization.

According to Frank, if in the previous debate it was thought that the rate of 1 in 10 billion planets would have been "pretty pessimistic" . But the findings of the two scientists show that even at the "pessimistic" level , there are about 1 billion civilizations growing in this universe.

Quatz had calculated in different regions of the universe and found that about 420 billion alternative civilizations existed and developed throughout its history.

Adam Frank and Woody Sullivan do not show how many species are currently coexisting. They said that it took a long time to have data related to that to work out.

Another mystery Quartz once wondered how long technology civilization lasted before disappearing. Before this, Sullivan joked: "We have many opportunities to find a modern technological civilization. On average, they (the civilization) are much longer than their current lives. I ".

Adam Frank and Woody Sullivan claim that humans are not alone, but it is very difficult to touch extraterrestrial beings because of the distance between galaxies and planets.
