Imagine a rubber band.  To the creature moving within it, it goes on forever.

Imagine a sphere.  To the creatures moving along its surface, it goes on forever.

Need I say more?

Thats an example of curved space which is just a theory,  I'd personally think it goes on forever,  but the human race will likely never know for sure!!

I agree with that. However, rather than we 'will likely never know', I would prefer to say we will definitely never know. We can't even comprehend infinity.

Yes. What you've said is true only for a spatially closed universe. For a spatially open universe space goes on forever.

Doesn't 'infinity ' exist only in a maths equation/formula somewhere ?

If one wishes, it was from imagination that such things could be borne.

Infitity to the scientist, means very little else than limits in physics. A limit itself can be indefinate reaching to the farthest sun, and still, infinities run the show all over the place. Theoretically, you could move millions of light years ahead, an still have an infinite path of space and time before yourself.

Equally you could count up all the fluctuations appearing in spacetime. But you would find, only a ghoslty appearance of an infinite amount of energy coming from the vacuum. Where does this energy come from? Why is the energy infinite... what does an infinite energy mean?

Infinity was more or less created by the imagination to account for expansions beyond calculation. Infinity means always that there is one more than now. In equations it works well to describe such natures, but remains itself as a headstone of authority when concerning such abractual idealogies.

Is there only one universe - or are universes continually being made - ad infinitum?

Continuously being made; governed itself by the wave function.

From a Copenhagenistic point of view.

You could argue that infinity exists, at least insofar as we can define sets of numbers with infinite members.  We can even simultaneously define infinities of different sizes too  ;D

For example, the set of positive integers has an infinite number of members because it is possible to always add 1 to the previous high value.  At the same time though, we can define an infinite set of fractions for every individual positive integer in the infinite set of integers by simply dividing it by every integer, so if the set of positive integers has an infinite number of members then the total set of fractions has infinity^2 members.

Lynda, which one would you like?
Nobody knows so you can pick your choice, this modern science of us is only two hundred and some years old. Not even a dot on Earths age. And as we can't pinpoint anything, although we are becoming very good on manipulating and defining the 'forces' we observe. down at that lowest level (Quantum mechanical) there is still room for, and with, views to rent, and keep :)

I bet space only grows, thus it is a size at any given time.

why would there be another universe when humans got this one so messed up...Not till peace in our universe.

I don't like the idea of the Universe being literally infinite in size; it would have required an infinitely-fast expansion to go from a finite size (Big Bang singularity) to an infinite size.
