Shcrödinger’s Cat is intuitive if the universe is lazily evaluated - everything is probabilities (or probability amplitudes, if we’re being technical) until an outcome is needed.
The box and cat and radioactive particle are in their own isolated system, cut off from the universe, so the universe can keep going without information from inside the box. From outside, the outcome in the box can remain probabilistic - it does not need to “be resolved”.
But inside the box (the isolated system) the cat knows very well if it’s alive or dead and the radioactive particle knows if it has decayed. The interior of the system must have resolved (an outcome was chosen) with respect to itself.
To match the first intuition, the universe must then be not merely lazily evaluated from your perspective, but actually lazily evaluated from every perspective.
Because everything is lazily evaluated with respect to everything else, this “inside the box or outside the box” lazy evaluation is happening all the time, everywhere. There’s no universal truth or sequence of events and there never was. There are only truths and sequences of events close enough not to matter at the levels of zoom humans operate at.
Whoa.

And if there are no particles before you arrive, what are you going to even observe? No wonder the universe's expansion is a accelerating, we keep looking at it!
