One of these days, a large comet will hit Earth and destroy almost all life, as has happened many times in the past.
Eventually, the Sun will expand enough to boil the oceans and destroy all life.
Either become a spacefaring civilization or die – those all the two choices.
@realMaalouf Legal question. If you immediately kill him is it justified? Seems like a reasonable response. You won't out run an explosion, but if it doesn't go off you can dispose of the threat before they have a chance to fix their malfunctioned device.
Claimimg communism abolishes class is conflated with abolishing hierarchy. The state becomes the high class and civilian the slave. Hierarchy is what these people truly have a problem with, and yet hierarchy exist in every facet of reality, including physics its self. Everyone who dreams of these illogical utopian ideas leave out free will, sin, and basic natures of reality. They're simply angry at God (the universe) for existing in the manner it does and are too consumed by their own ego to understand or conform to reality. The only reason they don't simply die is due to the stability derived from the modern world.
