 All right, and no Validity of measurement validity is anything that's true and capable of being supported So when we talk about measurement is the measurement true and capable of being supported. So for example, I'll give you a good one here. So We have intergalactic peace It's kind of a Star Wars thing. No Star Trek. Ah, shoot me. I said Star Wars. I'm at Star Trek I'm not a Star Wars. We gotta go. No Oh, yes, we cut that out. I hope. Anyway, so yes Star Trek intergalactic peace We have it. How do you know because we're not being attacked by aliens? Wait a minute. Do we even know aliens exist? Have we measured it effectively? Is it I don't think we've effectively measured whether or not there are no other lifeforms somewhere in our universe All right, we're trying and we haven't found it so far that science is always about the what we haven't found yet So anyway Yeah Validity of measurement did the kid really engage in the nasty behavior because you said he did or because you directly observed it or because it Was done on a piece of paper and a teacher said he did orbit the parents say they did did you actually see it? And better yet, did you see it and this person see it? Whoever that person is but they might have seen it too And if they both saw it then you have some some increased validity or least believability, which is another video So anyway, bye
