Hello.(adsbygoogle = window.adsbygoogle || []).push({});

I have been working through some questions and answers to do with cosmology. One of them asks you to consider a model where:

[tex]\Omega_{MO}=3 [/tex]

[tex]\Omega_{\Lambda O}=0.01 [/tex]

[tex]\Omega_{RO}=0 [/tex]

and asks you to show mathematically that the model re-collapses.

Following through the math, I get three values of a: -14.87,1.51 and 13.36.

Clearly the first can be disregarded and unphysical since a cannot be negative, but I can't decide whats the significance between the second two which allows me to isolate the value corresponding to collapse.

Cheers.

Adam
