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.
