The paradox of Schrödinger’s cat according to quantum mechanics (click to view)

In this famous thought experiment, a live cat is put into a closed box, together with a quantum trigger
that spills a phial of poison, so that the cat will die if a single particle decays.

The decay is certain to be detected and the detector is certain to liberate the poison inside the box.
The half-life for the decay is long, compared to the time required for the poison to kill the cat.

Thereafter, the system is described in quantum mechanics as a superposition of states in which
the cat is both alive and dead at the same time. The amplitude describing the dead cat increases with time
and the amplitude for the living cat decreases - they must follow the amplitudes
for the decayed and un-decayed particle.

Schrödinger’s point is that the course of history can never actually be decided, within quantum mechanics.
The theory is essentially incomplete, as a description of changes in the structure of matter.

**Interactions in Tri-space. **

Two systems (**a** and **b**) are brought close enough to allow interactions.
Each is driven from Tempospace (**T**) and the connecting wave function is projected into
the corresponding Real space (*r*).
The equations of connection (shown on Home page 2) are depicted below.

The Tempospace connections combine to drive the modified system with a scalar `Tempodriver' (*t*)
in the Centre of Mass frame.
All possible outcomes are driven (with the same total energy and momentum) in super-position.
This is equivalent to the QM description.
(Gravitation works differently and is ignored here.)

**Measurements in Tri-space. **

When a third system is introduced (denoted **O** for Observer), which has different energies of interaction
with **b** and **b'**, the system is resolved, selecting one definite outcome.
(It is not possible to drive states with different total energies in super-position.)

To make a classical observation, the detector may contain many copies **n** of **O**, which are
triggered by a single **O'**, so that the change becomes macroscopic.

Conclusions (click to view)

Given prior knowledge of **a** and **b**, the detection of **b'** can determine some
properties of **a'**, which becomes a separately-driven system.

In the case of Schrödinger’s cat, the spilling of poison follows from the detection of the elementary decay
and (the death of) the cat is the detector of the poison. Both processes resolve the wave function and they
both involve large changes of entropy.
For these reasons, the cat can never be alive and dead, although it must take some time for the poison to act.

The requirements of wave function unitarity and the conservation of energy and momentum
are not enough to describe the course of history. That must be determined by the collapse
of the projected wave function, which is caused, in Tri-space, by changes in the driving frequency.
No system containig multiple connections to external Tempospace can be described by a single wave function
(unless they are identical).

The concept of tempodrivers does not exist in quantum mechanics - it is logically missing.
