When we talk about the cat being both alive and dead, it's a simplification to help visualize a quantum phenomenon where particles exist in multiple states simultaneously until measured or observed.

Schrodinger came up with the cat to represent the absurdity of quantum mechanics because he thought it was absurd - but that doesn't mean his metaphor isn't a useful one. Particles like electrons or photons can exist in a state of superposition, where they hold multiple potential states (e.g., spin up and spin down) at the same time. This isn't just a theoretical curiosity; it's been experimentally verified in numerous quantum experiments, such as the double-slit experiment.

The act of measurement in quantum mechanics forces a system to 'choose' a definite state from among its superposed states, a process known as wave function collapse. Before measurement, the system genuinely exists in all its possible states simultaneously, not in one state or the other. This is a fundamental aspect of the quantum world
