> the black hole was 55 million light-years old. It is 55 million light-years away. Are these not basically the same thing ?

  No, just that our view of it is how it looked 55 million years ago. Time is relative anyway though, so...

  Nope; it means that the light we captured now took 55 million years (give or take) to get here, the black hole is likely much older.
