If you google gravitational singularity for the wiki link,you'll see infinity used as reasonable explaination . "yeah we can't go that far , so we''ll call it infinity and that explains that part"
A
gravitational singularity or
spacetime singularity is a location where the quantities that are used to measure the
gravitational field become
infinite in a way that does not depend on the coordinate system. These quantities are the scalar invariant
curvatures of spacetime, which includes a measure of the density of matter.
Infinity (symbol: ∞) refers to something
without any limit, and is a concept relevant in a number of fields, predominantly
mathematics and
physics. The English word
infinity derives from
Latin infinitas, which can be translated as "unboundedness", itself derived from the Greek word
apeiros, meaning "endless".

Very well - but the infinity associated with black holes has nothing whatsoever to do with whether or not the universe is infinite. Would you care to try again. What physical theory is different or rendered invalid if the universe is infinite rather than finite? Or vice versa.
it's very relevant..Any acceptance of infinity ncoupmasses the whole universe. Infinite "anthing cannot be a seperate state.
I must say i'm dissapointed in not getting reasonable discussion on this subject
You haven't helped matters by using vague terms and misapplying terms. It makes it very difficult to understand what you mean or what you are asking.
No ...I'm being quite clear. I have not seen any posts taking the time to think about what a finite universe would look like. That is my main point. I have had this discussion before and every arguement is pro infinite universe.
Taken from Wikipedia "infinity"
Cosmology In 1584,
Bruno proposed an unbounded universe in
On the Infinite Universe and Worlds: "Innumerable suns exist; innumerable earths revolve around these suns in a manner similar to the way the seven planets revolve around our sun. Living beings inhabit these worlds."
Cosmologists have long sought to discover whether infinity exists in our physical
universe: Are there an infinite number of stars? Does the universe have infinite volume? Does space
"go on forever"? This is an open question of
cosmology. Note that the question of being infinite is logically separate from the question of having boundaries. The two-dimensional surface of the Earth, for example, is finite, yet has no edge. By travelling in a straight line one will eventually return to the exact spot one started from. The universe, at least in principle, might have a similar
topology; if one travelled in a straight line through the universe perhaps one would eventually revisit one's starting point.
If, on the other hand, the universe were not curved like a sphere but had a flat topology, it could be both unbounded and infinite. The curvature of the universe can be measured through
multipole moments in the spectrum of the
cosmic background radiation. As to date, analysis of the radiation patterns recorded by the
WMAP spacecraft hints that the universe has a flat topology. This would be consistent with an infinite physical universe. The
Planck spacecraft launched in 2009 is expected to record the cosmic background radiation with 10 times higher precision, and will give more insight into the question of whether the universe is infinite or not.
Because the answer to whether the universe is infinite or not can be answered by the fact that we are self aware, it seems to me to be luducris that we aren't understanding it in this context. We should be better able to understand the sequence and therefore predict the actual size (both icro and macro using these parameters.
