Dust filled universe, is there a type of tension defined?

  1. Dec 21, 2009 #1
    Say we have dust filled universe. At some instant of time this universe has a mass density rho, and it evolves with time according to General Relativity. Is there a quantity in that universe that acts like tension? Can we associate something like tension in such a universe. Would its strength be related to rho?

    Thanks for any help!

    This is dark energy/cosmological constant, and its strength is thought to be independent of matter density.
