Scientists at the University of Nottingham have concluded that up to 36 ‘intelligent alien races’ are likely to inhabit earth’s galaxy. As The Sun reports:
Using the assumption that intelligent life develops on other planets in a similar way as it does on Earth, the research team obtained an estimate for the number of intelligent communicating civilisations within our own galaxy, the Milky Way.
They calculated that there could be more than 30 active communicating intelligent civilisations in our home Galaxy.
Astrophysics Professor Christopher Conselice, who led the research, said: “There should be at least a few dozen active civilisations in our Galaxy under the assumption that it takes five billion years for intelligent life to form on other planets, as on Earth…
First author Dr Tom Westby explained: “The classic method for estimating the number of intelligent civilisations relies on making guesses of values relating to life, whereby opinions about such matters vary quite substantially.
The stunning findings beg the question: are we truly alone in the Universe?
