Science is the process of trying to understand the nature of reality. And it's a fundamental of science that we believe reality exists, instead of having it be a human construct or all a matter of relative point of view. There isn't another side of the story in science. There are the right and wrong answers, and you do a better or worse job of understanding that reality, but we do believe reality is there. That's fundamental to what we're doing.
