Apocalypse How/Class X-4: Difference between revisions

** In ''[[The Hitchhiker's Guide to the Galaxy/Life, The Universe And Everything|Life The Universe And Everything]]'', the Silastic Armorfiends have commissioned Hactar to create a superweapon that will connect to the heart of every star in the universe and cause them to go supernova, effectively killing everything in existence. Hactar initially has second thoughts about it.

** Casually mentioned in ''[[The Hitchhiker's Guide to the Galaxy/The Restaurant At The End of The Universe|The Hitchhikers Guide to The Galaxy]]'' and ''Fit the Seventh'' of [[The Hitchhiker's Guide to the Galaxy (radio series)|the radio series]]:

* [[Stephen Baxter]]: ''[[Xeelee Sequence|The Photino Birds]]'' are deliberately turning every last star in their entire universe into a red dwarf, making it uninhabitable for all other life. In ''[[Manifold Time]]'', {{spoiler|the Blue children instigate a vacuum collapse incident, causing the fabric of space to collapse into a new energy state within a bubble expanding at lightspeed.}}

* [[Greg Egan]], ''Schild's Ladder'': A science experiment gone wrong creates a sphere of complete annihilation expanding at half the speed of light. The sphere actually {{spoiler|contains an entirely new universe filled with far richer and more vibrant life than ours}}, but that's small comfort to those in the universe being destroyed. {{spoiler|Except for the sufficiently advanced posthuman.}}

* Three words: [[wikipedia:False vacuum#Vacuum metastability event|Quantum Vacuum Collapse.]]

** The quote itself would be Crowning material if there were such a thing as a Crowning Moment of Doom.

* The [[wikipedia:Simulation hypothesis|Simulation Hypothesis]] puts forward the possibility that reality as we know it is no more than a simulation. If its creators or some other outside force were to turn it off...

** If they're running more than one simulation, this would be X-5.
