Only accurate information has practical application, so it doesn't matter what you wanna believe. All that matters is why we should believe it too, and how accurate your perception can be shown to be. You can't just make up stuff in science like you can in religion because you have to substantiate everything, and you have to be able to defend it—even against peers who may not want to believe as you do. Be prepared to convince them anyway. It's possible to do that in science because science is based on evidence and reason. That means you must be ready to reject or correct whatever you hold true should you discover evidence against it.
