Abstract: | The Weinberg relation (which connects the Hubble constantH to the mass of a typical elementary particle) is an empirical relation hitherto unexplained. I suggest an explanation based on the Zel'dovich energy tensor of vacuum in a Robertson-Walker universe with constant deceleration parameter,q = const. This model leads to - the Weinberg relation,
- a varying cosmological term Λ scaling asH 2,
- a varying gravitational constantG scaling asH,
- a matter creation process throughout the universe at the rate 10?47 g s?1 cm3,
- a deceleration parameter in the range -1 to 1/2, which allows a horizon-free universe and makes the lawG/H = constant, consistent with the Viking lander data on the orbit of planet Mars.
