Physics # Deconstructing Schrödinger’s Cat – Solving the Paradox

**The French theoretical physicist Franck Laloë presents a modification of Schrödinger’s famous equation that ensures that all measured states are unique, helping to solve the problem that is neatly encompassed in the Schördinger’s cat paradox.**

The paradox of Schrödinger’s cat – the feline that is, famously, both alive and dead until its box is opened – is the most widely known example of a recurrent problem in quantum mechanics: its dynamics seems to predict that macroscopic objects (like cats) can, sometimes, exist simultaneously in more than one completely distinct state. Many physicists have tried to solve this paradox over the years, but no approach has been universally accepted. Now, however, theoretical physicist Franck Laloë from Laboratoire Kastler Brossel (ENS-Université PSL) in Paris has proposed a new interpretation that could explain many features of the paradox. He sets out a model of this possible theory in a new paper in *EPJ D*.

One approach to solving this problem involves adding a small, random extra term to the Schrödinger equation, which allows the quantum state vector to ‘collapse’, ensuring that – as is observed in the macroscopic universe – the outcome of each measurement is unique. Laloë’s theory combines this interpretation with another from de Broglie and Bohm and relates the origins of the quantum collapse to the universal gravitational field. This approach can be applied equally to all objects, quantum and macroscopic: that is, to cats as much as to atoms.

The idea of linking quantum collapse to gravity has already been proposed by the great English physicist and philosopher Roger Penrose, but he never developed his ideas into a complete theory. Laloë proposes a model that goes in the same direction, agrees with physical observations and may one day prove testable experimentally. It is relatively simple – ‘naive’, even – and introduces only one additional parameter to the standard equation. Laloë is planning to explore more consequences of his model in different situations. Furthermore, he suggests that a theory that combines quantum mechanics with gravitation may have implications in astrophysics.

Add one special variable...... the "spooky action at a distance" variable, in the "faster than light" dimension.

Haha! Exactly, I saw that too ... Just a 'small, random, extra' term thrown in, nothin to see here folks.

Hindu mythology states there are infinite number of universes existing at the same place at the same time simultaneously with all possible permutations and combinations. This is very famous ancient saying. You can find references in old osho writings and vedas

A shift in the universe or changing the universe or changing the outcome basically means you as consciousness shift to another universe. In an existing universe the outcomes are fixated. So shifting into a universe is basically a faith shift. To shift to a universe where your dead father is alive and only you know that you have shifted will for most biengs will be a mental catastrophe hence small shifts with slight change and everything else constant do take place for average people with some spirituality.

It may very well be impossible to collapse Quantum. A singularity apart from multiple split of duality into our 70 trillion human cells and counting could not absorb unless somewhere in this Quantum singularity there is a cord or thread of disconnected wholeness which may, in fact be the G-particle with a capital"G".
