I don't know why you are spamming the thread insisting that you are correct. Nearly 100 posts in a 17 page thread insisting that you know better. Strange.
And on the other hand, YOU are not insisting that you know better ?
But anyway. Yes the spell says exactly that - it says you move from one place to another instantaneously.
No, it does not. Once more, just read it, these are not the words of the RAW.
You are at A. Then you are at B. No time separates A from B. An explosion happens after you leave A. You must therefore be at B when it happens.
Again, no, if it was written that way, I would accept it. But it's not the way it's written. All your pretend "demonstrations" where you change the words of the spell will actually only demonstrate that you do not have enough support in the RAW.
It's really very simple and only made complicated by people trying to rules lawyer in a time delay into teleportation, by exploiting the fact that the rules conversationally talk about 'disappearing', as that's what an observer would see.
Just as other observers, and they were a number of them, would interpret your reading as a DM trying to frustrate the players by a much too strong reading of a spell, thereby diminishing their fun for no good reason.
What's being disguised by trying to exploit that language is that it isn't what the caster experiences. They don't disappear, they move from A to B instantly.
And, in between, just as instantly, there is a boom, while the caster is in a transit that just takes "an instant".

It works just as well, is more fun for the players, and violates neither the rules not even potential physics even in the real world. The only thing that it violates are apparently your personal convictions, and to be honest I don't really care about them especially with the way you are expressing them.
