My long-ish counter argument to your post.

Meh, being trained in physics myself, I’ve given up trying do analyse the physical relation on animes involving physics. Think the closest an anime could get to accurate physics is Haruhi S2 (and that’s only because they’re using some ACTUAL physics equations in their OP animation instead of some random complex-looking mathematical equations).

PS: I swear I could almost hear Urobochi and Shinbo are gloating their asses of with “Keikaku doori”

Physforum, anyone?

All the abilities, powers, wish granting, all of it is done by the loli’s own spiritual power, literally the power of the soul or power of emotions. Kyubey’s race only has the technology to pull out souls and fabricate them into a Soul Gems. The lolis subconsciously do the rest. Homura’s time traveling, Sayaka’s healing, Mami’s revival, all of it was done by their awakened power based on their wish.

Souls in and of themselves are believed to not be ‘real’ when put in scientific terms. They wouldn’t follow the laws of physics. That means if you manage to physically manifest one it can fuck around with reality all it wants. They wouldn’t channel energy from another existence but produce their own energy. Considering the defeat of Walpurgisnacht in episode 10 released enough energy to fulfill Kyubey’s ‘quota’ one can conclude that Soul Gems produce unfathomable amounts of energy out of emotions.

Emotions aren’t a physical thing and are created by humans millions of times a day, so turning that into physical energy grants far more energy than you need to input. Eventually a Soul Gem-turned-Grief Seed would be full of emotional energy, allowing it to be swallowed by Kyubey (explaining why a single Grief Seed can’t be used infinitely to purify a Puella Magi).

It’s more of a ‘science and magic go hand in hand’ thing but more ‘science vs magic/religion’ thing. No matter what science does, it can’t fathom, explain or control magic. Same goes for deities. Souls come from religion in the first place, something which science can’t explain. The very concept of an almighty being doesn’t abide to physics, so souls wouldn’t abide to physics either.

Yes, this is all ‘a wizard did it’ explanation, but that’s because the show itself explicitly states ‘a wizard did it’. There’s no way around it. Kyubey can explain entropy, but he can’t explain magic since it goes against science entirely (that’s why it’s called MAGIC).

Also, regarding the ‘wish entropy away’ part, remember, these are teenage girls. This entropy deal would go way beyond their heads. At that age kids tend to put their own issues in front of everything else, so most of the time the girls will only make short-sighted or selfish wishes. It will be very hard to find a girl who wants to end entropy, or manipulate one in doing so. Besides, would you believe a small, creepy furball that he’s helping prevent the heat death of the universe?

More like farming Madoka.

In episode 10, Madoka gets more powerful with each successive leap. The previous iteration would have seen Madoka wipe out the planet rapidly, and QB has stated that Madoka could become a god in the current iteration, so eventually, Madoka turning into a witch will net enough power that QB can effectively remake the universe like in The Last Question. Probably the energy gain up to this point was a delaying tactic, with the appearance of the Madoka/Homura combo a welcome surprise.

All QB has to do is omit Homura to make sure she doesn’t reset it again.
