Einstein's field theory of elementary particles (Einstein 1919) yields
black holes with a mass M approximately G-1 LAMBDA-1/2c2 and a charge
Q approximately G-1/2 LAMBDA-1/2c2, their curvature radius is LAMBDA-
1/2. Here 4 LAMBDA is an integration constant of Einstein's ''trace-le
ss'' gravitation equations. The choice LAMBDA = G-1 h-1 c3 for this co
nstant defines Plackions and implies ''strong gravity''. The choice LA
MBDA = lambda = 3H(inf)2c-2 (where H(inf) means the Hubble parameter o
f a final de Sitter cosmos) involves ''weak gravity'' and describes an
electro-vac spherical universe.
