When

well, ill say this either a war or cern will end us, if a war was to happen it wouldnt require a single shot being fired. A well placed emp bomb in the right location of the world would most likly end most if not all being if our power grid went down one our generation would fall apart but not only that there be many nuclear plants melt downs and will explode being no way to control the fuel rods or cooling them, Thats one it just need 1 or a couple more emp bombs. two is cern with there particle accelerator, they basically making mini black holes with no knowledge of how to control them and or how to contain such a force, not to mention as we speak as far as public publications is shown they are basically nuking the dark matter at a sub atom level to extract the power out of them(Dark energy) so im saying cern/black hole or a emp bombs.
