A message arrives from outer space for all living beings across the universe. A crazy scientist decrypted it. it says something like:

"Warning! ... Asteroid out of control wandering! ... It contains the origins of the most dangerous weapon ever known! ... Enter the asteroid before it will destroy your planet! " .
