Barely in this. Mostly stating matter of fact, "I am correct and in five hundred years all is darkness."
500? I'll take those odds. Let the cats in AD +457 worry.
They send out the eggheads in a ship and tell them to reach the far end of the empire w/o using "jump drive." So in sixteen years maybe they leave the heliosphere? The attack craft for reprisal are assembled and reach destination in sixteen hours after terrorist act destroy the Sky Hook. Something attached to a planet that hangs in orbit can't be severed by an explosion. Maybe a monofilament saw? But it looked quarter mile across. Tough tree trunk to hue. Plus, the elevator sat thirty. Be rather worthless to only take thirty on a fourteen hour descent. Think they'd need a toilet.
The current crop of on-demand writers are image driven and poorly read. Hope they burn in hell. That felt good.
Rather watch Flesh Gordon (and that stunk, silly). Maybe that's the key, watch, mock and laugh, like original Dune or Adam West Batman.
