E.T. STAR WARS
Aliens ‘extinct due to conflict’
ALIENS keep wiping themselves out before humans get to meet them, boffins reckon.
Scientists from US space agency NASA say aliens, like movie hero ET, may have existed throughout the history of the universe but never hung around long enough to touch base with Earthlings.
The boffins suggest some will have been wiped out by uncontrollable events like an asteroid hitting a planet, while others may have been self-inflicted – such as via a nuclear war or climate change.
According to the study:
“Evidence of life should exist in abundance in our galaxy alone.
“And yet in practice we’ve produced no clear affirmation of anything beyond our own planet.
“So, where is everybody?
“The silence of the universe beyond Earth reveals a pattern of both human limitation and steadfast curiosity.’’
They also suggest an “existential disaster may lay in wait” as society advances towards space exploration and steps up the search for alien life.
