Stephen Hawking’s recent comments in a science show have ignited debate among scientists around the world. He had recently commented on the possibility of alien species and also that it will be wise for human beings to avoid contact with aliens.
He also guessed that these aliens will most likely be nomads and their visits to Earth should not be encouraged in any manner. Hawking had earlier in an essay in 1996 had written that until and unless the human race becomes more sophisticated, it should not try to get in touch with alien species.
There was also a lot of speculation related to the appearance of aliens and the way they may be dressed or their level of understanding. Some of the scientists were highly critical of Hawkins’s statements. But most of them agreed to Hawking’s analysis and felt that there is strong possibility of alien species and human race needs to be ready to confront them one day.
Oregon State University’s Blair Csuti argued that evolutionary principles will dictate behavior of aliens and they will be trying to defend their interests when they visit Earth.
Some also felt that the aliens will be highly developed robots like the ones shown in movies and may be only doing as directed by their controllers. There are also some who feel that it is not the technology but the possible pathogenic microbes which can have a lasting impact on the human race.
