“So trying to explain the Force with little mindochondria is futile”
Like trying to explain magic with the presence of a particular gene? :-D (BTW, yes, I know that that gene is not the cause of magic in HPMOR, but similarly midichlorians are not the cause of the Force in Star Wars).
And as an extension:
“In the world where midichlorians are needed to explain the Force, the Force simply doesn’t exist in the first place.”
A parallel statement about HPMOR can be constructed from that: “In the world where a gene is needed to explain magic, magic simply doesn’t exist in the first place.” which can be subsequently paraphrased as: “in a world where magic exists, a particular gene is not needed to explain it.”. Magic exists in the HPMOR universe. If the gene marker is not needed for it, am I correct in assuming that Harry James Potter-Evans-Verres will discover this at a certain point during the course of the story? Am I also correct in assuming that Harry James Potter-Evans-Verres will reach the further conclusion that, since his universe contains magic, he is living in a work of fiction?
Finally! Someone who explains (as opposed to simply downvoting) the weak points in my reasoning!
You’re right, the light horizon is something I had completely forgotten to take into consideration. Just as I read your comment, I was about to object that a FASI would be able to cheat and create wormholes or Tipler cylinders to violate causality and let us know it exists anyway… then I remembered that, even if it was capable to create them, they would not allow it to reach any point in time before their creation, so it would still be incapable to escape the boundaries of its own light horizon to reach ours.
Well, point taken.
