Karolyhazy's quantum space-time generates neutron star density in vacuum

TL;DR

This paper critiques Karolyhazy's quantum space-time model, arguing it overestimates uncertainty and leads to unrealistic physical consequences, thus failing to explain quantum coherence violations or predict tiny effects.

Contribution

It provides a critical analysis showing that Karolyhazy's model overestimates quantum uncertainties and cannot account for observed quantum phenomena.

Findings

Karolyhazy's model overestimates quantum space-time uncertainty

The model leads to physically absurd consequences

It cannot explain quantum coherence violations or tiny effects

Abstract

By simple arguments, we have shown that Karolyhazy's model overestimates the quantum uncertainty of the space-time geometry and leads to absurd physical consequences. The given model can thus not account for gradual violation of quantum coherence and can not predict tiny experimental effects either.
