SUMMARY
The forum discussion centers on the Friedmann Equation as presented in "Introduction to Modern Cosmology" by Andrew Liddle, specifically addressing Equation (3.4) related to the potential energy of a test particle. A participant questions the accuracy of the equation, suggesting a missing factor of 2 in the denominator. However, others confirm that Equation (3.4) is correct as stated. For further clarification, Liddle provides corrections on his website.
