stephaneww Posted October 25, 2021 Share Posted October 25, 2021 (edited) Hello it is again a function of Hubble time tH =1/H as here : https://www.scienceforums.net/topic/125960-why-this-egality-is-exact-please/ you will not have the referential immediately, so don't contest with dimensional analysis please. here his equation, you will adapt the dimensions: [math]\rho_{\text{Vacuum at }t_H}= \frac{1}{ \vartheta} \frac{ G \text{ }m_{Pl}^2}{ (t_H\text{ }c)^2} [/math] with : [math] \vartheta=2 [/math] if tH>tPl (1) and [math] \vartheta=1 [/math] if tH=tPl (2) can you please confirm that : (2) give the exact numerical value ? and that (1) is a good approximation of the measurementsis a good approximation of mesures ? thanks in advance stéphane Edited October 25, 2021 by stephaneww Link to comment Share on other sites More sharing options...
stephaneww Posted October 25, 2021 Author Share Posted October 25, 2021 (edited) ooops I forget because the question of dimensions we have: (1) ρvac in m-2 when tH is big enough (2) ρvac in kg/m3 Edited October 25, 2021 by stephaneww Link to comment Share on other sites More sharing options...
stephaneww Posted October 26, 2021 Author Share Posted October 26, 2021 (edited) sorry I made a mistake : the egality (1) is in m-2 the egality (2) in Joules precision on the question of the dimensions : in the egality (1) it is because we have a singularity and in the egality (1), two square surfaces. so with this presicions : can you please confirm that : the egality (2) give the exact numerical value of Planck energy? and that the egality (1) is a good approximation of the measurements of mesures of cosmological constant ? thanks in advance Edited October 26, 2021 by stephaneww Link to comment Share on other sites More sharing options...
stephaneww Posted October 26, 2021 Author Share Posted October 26, 2021 (edited) and I made also an error in the formula 😡: there was an extra square in the denominator note that now the equation has the dimension of an energy Edited October 26, 2021 by stephaneww Link to comment Share on other sites More sharing options...
