Talk:Alien Megastructure

Speedy
Disinformation. Metallic asteroids exist bu tare not alien megastructures. Similarly all non-terrestrial material does not have to be an alien megastructure. By that definition the sun would have to be considered an alien megastructure (we don't have natural hydrogen fusion on earth). Meters (talk) 22:16, 18 January 2016 (UTC)
