The Cost of Visiting Earth May Be Too Astronomical For Aliens

The Cost of Visiting Earth May Be Too Astronomical For Aliens
MATT WILLIAMS, UNIVERSE TODAY
27 DECEMBER 2020
In 1950, Italian-American physicist Enrico Fermi sat down to lunch with some of his colleagues at the Los Alamos National Laboratory, where he had worked five years prior as part of the Manhattan Project.

According to various accounts, the conversation turned to aliens and the recent spate of UFOs. Into this, Fermi issued a statement that would go down in the annals of history: "Where is everybody?"
This became the basis of the Fermi Paradox, which refers to the disparity between high probability estimates for the existence of extraterrestrial intelligence (ETI) and the apparent lack of evidence.
