... I'm sorry to say that was a joke, because well, capacitors like to go boom (MLCCs as in here not so much, but still).
What I do know though is that these MLCCs often dramatically change their actual capacitance with temperature, so maybe this is a sort of "temperature isolation" to keep the capacitor more stable? Honestly, no idea though.
Project hail Mary was cool in the fact that it was just so... Different. Won't say too much to avoid spoilers, but I think it'll tick your boxes.
