Aliens have been a fascination that has gripped humans throughout their history. For thousands of years, people have looked up at the sky and wondered if we are the alone amongst the stars or if there is life on other planets. This has obviously led to researchers and scientists trying to find out exactly that, with much of the work concentrated on trying to communicate with other intelligent life. In pursuit of that goal, scientists have come up with some truly strange ways of trying to contact aliens.
Some scientists believe that the energy levels of the Large Hadron Collider will be sufficient for it to generate and detect mini black holes that could allow researchers to study other dimensions, opening up possibilities of contacting alien life. Some also believe that the massive power output of the collider may even be large enough to be detected by aliens on other planets.
One unique project that NASA worked on in the 1970s was the Voyager mission. This sent several probes into outer space that contained a golden vinyl record that has recorded music, sounds and speech, along with information on how to extract the data from the vinyl.
