What is space?

[stephen h]

tell what space is within the confines of the universe. discuss all aspects of space and how to identify space.

That is a very broad question. What have you read so far? Why didn't the answer satisfy you?

 

[stephen h]

defining space will give us an idea of how large the universe is and how it might expand.

We already have a detailed model of this in cosmology. Have you looked at it?

in wikipedia what i have read describes space mostly in terms of matter plus cosmic radiation without mention of how they interact to form space or the universe.

yes and most references that is have seen are very general. the reference to cosmic radiation could be most revealing. the vast extent of the radiations (all types) far exceeds the imagination and is totally unmentioned and undescribed.

in wikipedia

What page? Please give a specific link.

most references

What references? Be specific.

Have you read any actual textbooks or peer-reviewed papers on cosmology and our best current model of the universe?

Have you read any textbooks or papers on General Relativity, which is the theory we use to build our best current model of the universe?

If a phenomenon exceeds the imagination then perhaps it is time to adopt a mathematical description and reason logically from that. This is vastly preferable to reasoning from dreams and puffery.

@stephen h note that you marked this thread as "Graduate". If your answer to either of the questions I asked above is "no" (and I suspect your answer to both of them is "no"), then you don't have the background knowledge for a graduate level discussion of this topic. In any case, we need to have an idea of what, if any, background knowledge you do have.
