    Default The slight vacumm of space

    IF the slight vacuum of space is due to Dark Energy(the expansion of the Universe):would this imply that if there were a slight pressure in space that the opposite would be true? and If there were neither vacuum nor pressure that the Universe would be static?

    Vacuum is absence of matter and not to be confused with the pressure in GR. I suppose you mean if the dark energy component were different.

    Yes then the situation would be different, but according to Go a static universe is highly unlikely.

    You say that " Vacuum is absence of matter " but I'm talking about the slight vacuum of space (or DARK Matter, if you go with NASA's latest thinking on space = Dark Matter) then this vacuum would seem to be interspersed amongst matter indeed- just Dark Matter . . . . . Right?

    As far as I know dark matter is believed to be an undiscovered type of particle. The formost contender being Wimps. Dark matter is beleived to de distributed as a halo around concentrations of baryonic matter (the normal stuff). Both dark matter and baryonic matter induces gravity. Are You talking about the slight pressure induced by curved space in areas of the halo where the concentration of baryonic is low? Even better do you have a link?

    With pressure i mean the pressure component in General Relativity.
