Two Dimensional Heat?

  1. May 5, 2004 #1
    How does HEAT, get transfered form one location to another in only a two-dimensional field?

    If we define the Cold Vacuum of space as a field background(I believe current models define Einsteins field Eqautions as being Vacua dominant), just how does thermal Heat move across Space?

    Heat conduction in materials is governed by the heat equation:

    [tex] u_t = u_{xx}+u_{yy}[/tex]

    In free space or even still air the main mechanism for heat transfer is Radiation. Seems to me that the energy goes like

    [tex] E= \sigma \Delta T^4 [/tex]

    here [tex] \sigma [/tex] is the Stephan Boltzmann constant.
