The Fermi Paradox
Erasmo Acosta

Erasmo Acosta discusses possible solutions to the Fermi Paradox. In 1950, physicist Enrico Fermi asked “Where is Everybody?” He was referring to the size and age of our galaxy, and to the fact that a civilization only a few million years older than ours should have already completely colonized the Milky Way. So where are the aliens? Mr. Acosta was raised by an atheist family in Venezuela. He came to the U.S. in 1996 as a software engineer. He currently works in cyber security for an Israeli software firm.
