Every Time.

• Every time you try to drag real life physics into a made-up setting, God kills a catgirl.

Consequentially,

• Every time a physicist plays God, we get one step closer to making catgirls reality.
• Every time Schroedinger thought about catgirls, Gernsback frowned and sighed "God..." while leafing through a bad manuscript.
• Every time someone calls the Singularity "The Rapture of the Nerds", some catgirls get physical with each other.
• Every time you ask about Tipler in a lecture on General Relativity, you'll get frowned upon.
• Every time a bookstore clerk files "The Call of Cthulhu" under "Science Fiction", a lonely physicist googles for catgirl pictures.
• Every time a lonely science fiction fanboy feeds his cat, he fantasizes about studying physics and finding a proof for God's non-existence that'll show those stupid theologians.
• Every time a physicist complains about poor characterization in an SF novel, a catgirl quotes Nietzsche.
• Every time God checks on his Catgirl Planet, he reminds himself to have a look again at that Monkeyboy Planet soon.
• Every time you mention catgirls into a discussion on applied theology, a physicist writes some Permutation City self-insertion fanfic.
• Every time a catgirl tries to understand Permutation City, God finds himself in the dust.
• Every time a catgirl tries to understand physics, nyaaa!
