Description
In this talk we review the concept of "universality" in the development
of very high energy cosmic rays showers. The main result
is that the distributions of photons and electrons in a shower
have shapes that are essentially determined by the
the stage of shower development (the shower age)
independently from the energy and identity of the primary particle.
The implications of this result for the interpretation of
the observations will be discussed.
