Unfortunately movies like Interstellar (which I love btw) make it seem like simply entering a black hole would reveal all sorts of secrets of the universe to an observer. All we really know is that most of our physical models break down in there, and without a massive lineup of experiments and machines to conduct them to take into the black hole, let alone the current impossibility of doing so, it would be akin to you doing 5 tabs of acid and then telling the rest of us 'you've figured it all out'.

The latter would be a lot more enjoyable.
