In the vastness of the cosmos are alien civilizations common or are they few and far between ?
In the 1960s astronomer Frank Drake devised an equation that he believed would provide an answer to this question, it uses a series of estimated values to come up with a likely number of contactable civilizations. Whether this equation is in any way accurate however remains to be seen - until we are able to map out every advanced civilization in the galaxy we will probably never know for sure.
In the 1960's, U. S. astronomer Frank Drake started the first real search for alien radio signals being beamed across the Universe. Off the back of this work, he came up with an equation that is at best, an educated stab at the number of civilizations in our Galaxy with which we might actually be able to communicate right now.
