With the LDCM, cosmological constant, model I understand that the scale factor of the Universe grows more rapidly than the Horizon. I believe the correct horizon I need to be considering is the Hubble Horizon and the point when objects recessional velocity hits the speed of light they disappear from our view. From this I'd expect to be able to calculate the time it would take for an object at some distance from us to move to this point.(adsbygoogle = window.adsbygoogle || []).push({});

Is there a neat equation for this or is there an issue with my understanding of what's happening?

If it makes sense but there's no equation that can be given, could somebody give me some steps on how to begin?

I also came across this calculator, which gives a recessional velocity of an object at redshift 1.65 to be greater than the speed of light. Have I interpreted the definitions wrong or is that the limit of our observible universe?

I am a third year physics student so I'm pretty comfortable with mathematics and if you think something is a bit beyond my level I'd still like to take a look.

Thank you
