Please don't take it to seriosly.

It was just a question. Perhaps the wording was to offensive for your liking. I apologize for that. And no, your post wasn't outrageous.^^
Anyway... What do you think about Ganonslayer2000's statements? For me he just focus just on a few things, without to take the whole matter into consideration. For sure the Entombed Alive statement would be surely logical under normal circumstances, if the DoT can only be opened from the front with the keys.
However the Sages who built the temple and their successors, would not have the problem to open the door. Also we should not forget that the Temple of Time has also some powers of time itself as it showed us in Twilight Princess.
But it is too farfetched to say that, when Link returned at the end to the temple of time, that he was in a temple of time, which existed in adifferent time and space. You might call it a pocket dimension, a temporary rift of space and time in form of a invisible bubble. When you leave it, you will be in a different universe. In this case, the spacerift was in connection with the Adult Timeline, while the outside is a universum which appears to be same, but younger as the other.
When Link gets outside of the bubble, he will takes the place of his counterpart in, meaning that the two links merged or just one was erased from existence.
If you have played Chrono Trigger you might get what I am trying to say. Anyway this theory that Link was in a pocket dimension in form of a temporary rift of space of time is to ludicrous.
It is a shame that the powers of the temple of time aren't documented in a official sourcebook.
