The alleged existence of so-called Planck particles is examined. The various methods for deriving the properties of these "particles" are examined and it is shown that their existence as genuine physical particles is based on a number of conceptual flaws which serve to render the concept invalid.

1 Introduction

The idea of the so-called Planck particle seems to have been around for quite some time now but has appeared in a number of totally different contexts. It seems to have been used initially as a means of making equations and expressions dimensionless by making use ...
