Since occupied space evolved from empty space, how/why did that happen?

It is a good question, but your premise is without basis. There is no conceptual problem with the idea of 'empty' space; that is, space measurable in spatial dimensions, but containing no matter. Similarly, there is no conceptual problem with the idea that space exists eternally, even if matter does not. Those statements are equally true in regard to time. But I see nothing requiring either to be true. It seems equally plausible that God created space and/or time as part of the same creative act in which He created matter. I have seen no evidence which is in any way helpful toward answering these questions.

Who told you that ???

Don't believe everything you read or hear, no matter how authoritative the source.

The 'Big Bangers', whose theory, by the way, is still just a theory ( and not even a very good one ), seem to assume that the infintessimally small clod of matter that just decided to go 'critical' and explode and cause our Universe to come into existence, did it in an enormous 'space' called 'Space'.

It didn't, I don't believe, the much more probable version is that the space is, actually, an integral, and essential, part of the whole.

Solidity, we know, is the great illusion. Any matter, when observed in the minutest detail possible, turns out to be almost entirely composed of enormous amounts of space with a dismally small quantity of bits of 'stuff'. Thus, no matter if it is Plutonium or Hydrogen atoms you are looking at, the quantity of quanta that it hangh on is minimal.

Thus 'space' is far from being an 'empty' medium, it is the very framework upon which 'stuff' is composed.

As our Universe apparently 'expands' so, naturally, 'Space' expands with it, yet we refer to the Universe as an 'object', while Space is a .............good question...........what ? The answer most theory would support is nothing.

I believe that 'Space' is far from being nothing. And it's potential, in measurable terms, is infinite.

What makes the whole process grow is thought, and this works for both the religiously inclined and the scientific. The biblical start is 'Logos', the word, and this can only reasonably interpreted as 'Thought', and that all 'things' derive from that 'First Thought'. Scientifically we have arrived at the realisation, through advances in quantum mechanics, that the observer plays a very literal part in the observed, which also supports the principle that it is the thinking/thoughts that drive the creative process.

No empty space, just potential.

Occupied space evolved from empty space because someone moved in. The reason they did was that the area they came from was too full.

Your question though is whether space existed then matter (mass) came along to occupy some of it. The answer is no. Whether we are looking at the big bang or continuous creation theory, (both of which are fatal to "Christian" fundamentalists) there appears to be no space without matter.

How can you define space without reference to something material? Is a cubic parsec of absolute vacuum any different from a cubic nanometer of a perfect vacuum? Takes less time for a photon to pass through, but a photon does not "feel" time. So to a photon both are the same.

Matter, (energy) space and time were all created in the same process. They are quite probably three aspects of fundamentally the same thing. Three sides of the same triangle for the trinitarians, maybe gas, liquid and solid for a poor analogy.

You are making an assumption that invalidates the entire subject. What makes you think that occupied space evolved from empty space. Prove it.. This is more a theological question than a scientific question.

an atom has a diameter of 10 means -10. and that of nucleus is 10 means -14/-15. [very virtually negligible]. so, there is not any hazard for neutrons and protons. Electron is the smallest particle in atom. so, answer is EMPTYSPACE. [rutherford additionally mentioned the comparable] emptyspace occupies extra suitable than ninety% of an atom!

You are right,occupied space evolved from empty space.

Space is a quantum entity that is the precurser to our universe,us and all we experience to-day.

It is the quantum aspect,the imperfections that allowed the universe to evolve into it's present state.
