There is a very high-level principle that says that something and its opposite can not exist at the same time. Smith can't be alive and dead at the same time.
Any science that claims that a "cat" can be alive and dead at the same time is invalid.
Particle physics is not a true science.
Oh I am not so sure about that.
I have heard rumors about men that are married and happy at the same time. Just because I have never seen it doesn't mean it isn't true.
Yes, but at least there is a huge amount of anecdotal evidence for it, collected from women.
