    Is Schroader's cat a true paradox?

    I have never consider the paradox of Schrodinger's Cat a true paradox, because it was based on assumptions from a limited human perspective concerning unknowns of Quantum Mechanics.

    Deconstructing Schrödinger's cat

    Many physicists have attempted to explain the problem of quantum superposition, as exemplified by Schrödinger's cat. Now a French theoretical physicist proposes a novel possible solution, which combines two different approaches and brings in universal gravitation.


    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.

    You can easily tell if the cat is dead or alive after about a week by the smell.

    If you leave the box sealed for that long the cat will be dead anyway.

    Let's deal with the paradox and leave the poor cats out of the box.
