comment Is there some special cutoff density after which spacetime “collapses” and forms a black hole?
@Qmechanic : not really that question is about the density of black hole, this question is about density threshold where the space collapses and black hole forms.

Thank you Brandon, yes, that is the question I updated the title.

my point is at what density, the fabric of space breaks down and at beyond that point only black holes with infinite density can exist? in other words what is the upper limit for density before space break down? What is the value of $x$?

comment If nothing is “objectively real” prior to “measurement”, what exactly is a “measurement”?
+1, god damn good question

comment What is the current radius of cosmological event horizon?
@Johannes : I am not looking for changes of cosmological event horizon in time, but that right now given that $H_0$ is constant in space, then what is the value of cosmological event horizon right now?

Explained that looking for cosmological event horizon at this point of time only

comment What is the current radius of cosmological event horizon?
@LuboŇ°Motl : because of the first line of the answer , I wasn't sure if my question was implying the contrary, I wasn't questioning Johannes but confirming that my question is not implying the contrary. the result I ended up with was $13\times10^{10}$ it is 3 times the answer of from alpha. My question is at this point of time, how far is the cosmological event horizon? If it was possible to take a snap shot of universe, with given $H_0$ at this point of time, since it is not dependent on time.
