  "There are several interpretations and approaches to relativity. All of them
are characterized by the fact that none of them is accepted by physicists
without doubts, even the Einsteinian General Relativity! Only those theories
can get into the spotlight that predicts something that is different from
predictions of other concurrent theories. From this point of view the theory of
Janossy [1] is not an excellent idea, as he tried to show that his
materialistic approach also corresponds to the general principles and equations
of relativity. As his program was basically successful there was not any
additional result, except the philosophical part."
  Since the death of Janossy, his work has almost been forgotten. Both what he
achieved and what he was not succeeded in. He was one of the founders of KFKI
(Central Physics Research Institute of the Hungarian Scientific Academy) but
his effort has not been carried over even there, however his collegues are
still remember his name and his work. Luckily his books are still available in
the Hungarian libraries. Additionally the most informed etherists in the world
who are lucky enough to know his work are consider his work as a No1 reference.
  This paper is designated to refresh the idea of the ether based gravitation
theory of Janossy and introduce a well founded way to adjust it to be
equivalent with the experiences and General Relativity.
