Foreign media reports, according to a new study by British scientists, humans may not be alone in the Milky Way. The expert involved in the study points out there could be more than 40,000 advanced civilization scattered in the galaxy.
So far, there had no wisdom life been found outside the earth. Skeptics even claim that there may hide other types of intelligent life in our earth.
Researchers, Frank Drake, in Edinburgh observatory, was trying to build a number of process of life in the Milky Way is used to test the model recently. To this end, he also exploited in recent years to obtain the other celestial bodies chemical composition and the quantity and characteristics of a planet outside our solar system and other data.
By comparing the result of various models, Frank Drake concluded that there may be 30,000 ~ 40,000 higher intelligence civilization in the Milky Way and they have the ability to completely establish contact with the earth human civilization.
The formula is put forward by the astronomer Frank Drake, now we call the Drake equation, to reveal the possibility of the existence of e̳x̳t̳r̳a̳t̳e̳r̳r̳e̳s̳t̳r̳i̳a̳l̳ intelligence. If a civilization is able to overcome the initial technology lead to the tendency of its own destruction, the civilization can continue quite a long time.
If this conclusion is correct, the whole number of c̳i̳v̳i̳l̳i̳z̳a̳t̳i̳o̳n̳s̳ in the Milky Way will be very large.
