How many stars fall beyond the Cosmological Event Horizon per year (or per second)?
Hello, I am trying to estimate how many unborn human lives a single second of delay in universal colonisation costs.
To get an accurate value, I need to know how many stars fall beyond the Cosmological Event Horizon (where they become unreachable from Earth at the speed of light).
I could not find a source on this value. I could get an estimate by calculating the difference between the volume of the sphere encompased by the horizon and the sphere encompased by the horizon - radius velocity/one second. This would give me the average number of stars in the sliver of volume that would move beyond the horizon in the span of a single second.
But this would not account for the distribution of stars in our "local" space. Like, I heard we are somewhere in the Great Universal void (the Boyes void?). So the star density could be far lower if the horizon edge passes through this or some other void. Or far greater if it passes through the dense regions.
I will estimate it roughly if I have to, but if the astronomers already did the calculations better, I would love to have the results. Surely some astronomer calculated this right? I could not find it googling.
