The trouble with the viability of time travel is though the math says it is possible, the same math breaks down in the presence of a black hole.

Obviously that is not true.
The trouble is mixing apples and oranges. Repeating decimals are not exact numbers, but rather representations. In limits, they have a defined purpose, but in standard algebra, they cannot be simply compared.
And no, 1/3 does not equal 0.333 for the same reason. 0.333 is only a best decimal representation. Infinities of any sort must be used with caution and understanding.
You make people miserable and there's nothing they can do about it, just like god.
