## Main Question or Discussion Point

In the thought experiment known as Schrodinger's cat a cat is placed in a sealed box, and its life or death is tied to an uncertain quantum event such as radioactive decay. If the radioactive particle decays, the cat dies. If not, nothing happens.

According to probability collapse QM, as I understand it, the cat is in an uncertain state until we open the box and collapse the probability wave created by the quantum event. But what if we wait ten days to open the box? Will we discover that, if the cat died, its body has decomposed for up to ten days?

But when did the ten days of decomposition occur (or become certain)? Does probability collapse theory claim that the death of the cat does not occur (or become certain) until we open the box and the decay too is uncertain even though the biological process will appear to have taken up to ten days?

Or does the probability collapse theory of QM imply a backward in time causation?
