Expert.. n. A person with more data than judgment.

Now I'm off in the weeds. What is an expert? Right now there are very solid theories of travel at speeds greater than light; alternative universes, to include a plausable theory that what we see and call space is in fact a hologram. If so, who is the man behind the curtain operating that machine?! Heck, I've even read of new theories, formulas and technology that challenges gravity, which should be the most solid truth in science.
I've heard that from the time a doctor graduates from university to the time they retire 40% of what they have been trained on and practice will prove to be inaccurate.
Experts are those that possess a great deal of knowledge that is likely mostly up to date. With Killer Whales, we know what we know until new information comes along. Again, I wouldn't be surprised to learn they have in fact sunk small boats, killed people, etc. I have no evidence of it, just speculating.
All of this aside, I liked the movie. I know it is biased and there is always the other side of the story. Good information to process and debate to have.
