Translation:If you do not believe the scientific facts, this is your problem.
As an aside, it's practical when ending business mails. At work, we always end our mails with:
"Sorun(un)uz olursa lütfen bize yazın."
If you exlude the parentheses, you get: "If you have a question, please write to us."
If you include the parentheses, you get: "If you have a problem, please write to us."
So it's handy.
