Well, you're assuming most people also reckon the blue energy released is also from the reactor core, and I don't think that's the case. I for one take the blue energy to be from Palpatine, an explosion of all his power when he dies. And yes, it looks like he's falling into some kind of reactor core, but logistically that's not possible. First of all, he's falling down the lift shaft, not a reactor core shaft, and second, he only falls for a few seconds, several hours too soon for him to reach the core. If he falls for six seconds before exploding, he would be travelling at 270,000 km per hour.

You keep saying that he's falling down the lift shaft not the reactor core shaft. Please explain how you know it to be a "lift shaft". You also say it would be impossible for him to hit the core that quickly. Who says he did? I never saw it as him reaching the bottom, but coming into contact with, and disrupting, the energy a certain point down. You can't see a bottom to the shaft, nor does it look like the Emperor ever impacts on it.
