Ever since humans acknowledged the hugeness of the universe , scientist have thought that there must be life somewhere other than earth, Either in our galaxy or even some galaxies far, far away. If the whole universe contains billions of galaxies, and if each galaxy contains billions of stars but if a fraction of those stars have Earth like planets, then possible hundreds of alien life must exist across the cosmos. For a while, science contented itself with logic alone. Then, in 1995, astronomers located the very first planet outside of our solar system. Since then, they’ve discovered nearly 300 planets outside of our solar system. Although most of these planets are large and hot which is very similar to Jupiter (which is why they are easier to find), smaller, Earth-like planets are starting to reveal themselves. In June 2008 European astronomers discovered three planets all just a little bit larger than Earth, these planets are orbiting a star that is 42 light-years away. These discoveries have served as an affirmation for thoese who were involved with the search for extraterrestrial intelligent life also known as SETI. Harvard physicist and the leader of SETI Paul Horowitz was stated in a 1996 interview with TIME Magizne, “Intelligent life in the universe? Guaranteed. Intelligent life in our galaxy? So overwhelmingly likely that I’d give you almost any odds you’d like “ And yet Paul’s enthusiasm must be attempted to be proven wrong by what scientist call the Fermi Paradox. This paradox’ first spoken of by a nuclear physicist named Enrico Fermi in 1950, ask yourself the following questions : If extraterrestrials are so common how come they haven’t visited? Why haven’t they tried to communicate with us? And finally why haven’t they left some kind of evidence such as heat or light or other electromagnetic offal’s maybe extraterrestrial life isent so common after all. But perhaps extraterrestrial is hiding from human civilization, if only...
