Actually, not only can the cat in this theory be both dead and alive, there's a third possibility as well - it could be in the course of dying (e.g. the flask is broken the moment the box is opened) when the observation is made. That's the key, ALL possibilities exist simultaneously until the observation is made.

This is that I was thinking Mr. Sukoi .

Its just sounds like High-Filudent Bullshit to me.

yeah, I'm not gonna know if the cat is dead or alive until I see it. I can not trust to radioactivity to reach the point, and I also can not trust that the poison will kill that cat, so.... WTF?

I guess at this point the cat can be dead or alive, and since IDK it's both dead and alive, or the equivalent there of. What if the neko is neither dead nor alive, to me there is no such plane of existence. You Are, or You Are Not.

Edit: I'm a bit buzzed. I'm ready for tomorrow. This is very interesting to me.
