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