Given that we have no such mechanisms and don't know what they would actually entail its hard to speculate, but suppose you opened a wormhole to such a remote place, you'd never be able to measure the distance there.Well, this may be true, but I think its not really established. Again, questions of definitions like 'space between'. Science can only work with what is observable, what isn't observable in some fashion doesn't exist in some fashion either. Perhaps the effects of this 'continuous, smooth space' ARE significant and it is exactly that, real. I don't know. When one starts talking about places you can never go or see and things you can't ever measure the philosophical ice gets real thin for everyone <img src="https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f609.png" class="smilie smilie--emoji" loading="lazy" width="64" height="64" alt=";)" title="Wink    ;)"  data-smilie="2"data-shortname=";)" />. BUT there will demonstrably be no way to communicate any information from A to Z, even using these intermediary points, as the expansion of space will require that you establish new intermediary points at a rate that is impossible, the number of them will grow to infinity before any information passes along the chain. Any two points which are NOW not every going to be in contact again will fall into this category, you can't get around the speed of light. The distance between A and Z is not actually 'infinite', but it is growing at greater than C. Now, necessarily there was some point in the past where all these points A, Z, and all the ones in between WERE in communication with each other, around 10^-34 seconds after the big bang as I recall, when the Universe was in thermal equilibrium before inflation blew it up. Some points may have been in contact long after that, indeed some fall over our horizon all the time even now. Maybe that matters, maybe not so much, particularly with points we've not been in contact with since the start of inflation.</blockquote>
