  Data on electromagnetic form factors of proton, neutron, and $\Lambda$ from
annihilation and scattering reactions are collected and interpreted in the
frame of a generalized picture of the internal structure of baryons which holds
in space-like and time-like regions. It is shown that these data give an
insight of the space structure of the baryon for distances one hundred times
smaller than the baryon size and, in the time-like region, a vision of the time
evolution of the hadronic matter for times up to $10^{-25}$~s, that is two
orders of magnitude shorter than the time taken by the light to cross the
volume of a proton. In the proposed interpretation, the electric form factor of
the proton in the space-like region can not cross zero, but vanishes or stays
very small, as an extrapolation of the data seems to show. In the time-like
region specific structures appearing in the data give evidence of the dominance
of the quark-diquark structure in a specific range of time of the evolution of
the system.
