Real science.
I did show you "real science," in the sense of quoting a piece of information--the worldwide network of sharp-eyed amateur observers which have seen precisely nothing--which makes the existence of Planet X as it has been described physically impossible. I don't know what other "science" is required. Sometimes just observation and common sense is sufficient. I should not have to perform an actual experiment to prove that I cannot fit a battleship into a phone booth.
And yes, I do lose patience sometimes when people are unable to think rationally about these things.
