Unfortunately, I don't think that's what the TOE is for. TOE wants to unify currently disconnected theories of physics. But, two observers would only be able to apply it to their own observations, which would be different in the first place. Different inputs lead to different outputs.
Think of basic
time-dilation for near-lightspeed travel. A TOE wouldn't be able to say how much time
really passed during the trip, for all observers. For the travellers, one amount of time passed, and for the people left behind, a quite different amount of time passed. There's not a single right answer.
From here, it's not too hard for me to extrapolate that a whole lot of what I consider to be reality is merely rooted in what I personally perceive. I can imagine how someone with a different set of beliefs is experiencing a very different world than I am. I'm an Atheist, so I see proof of this every time my Christian friends say that God did something. For them, He did. For me, there is another explanation.
