Re: Feo2: the universe (Feo Amante)

"But the cosmological horizon is only determined by what we are able to see with our latest tech, isn't it? It is only because the absolute faintest light that we can detect is what we have given as our horizon."

Yep, pretty much.The other definition is that of the farthest region causally connected to us.Beyond that,who knows.
And it increases in time, true, but so slow for us humans...

"Also, isn't the cosmological horizon model used only for statistical purposes,"

Nope.Actually, it depends on the statistics you refer to. It is the simplest solution to Einstein's equations for a homohgeneous and isotropic universe, that includes expansion and inflation.

"and that in turn is based on a lot of assumptions (granted they are educated assumptions, but still)?"

Well, sure there are assumptions, but for the time being, they seem to be supported buy the evidence.And quite well I might add (sure, within reasonable bounds).
