Expanding time?

Can anyone answer this for me?When space expands is there a reduction in anything?Is there less of something when space expands?

I ask because it is difficult for me to imagine the universe expanding unless as it expands it is taking up more and more space. In other words I conceptualize that beyond the ever moving boundary of the universe there is true nothingness of space being more and more encroached upon.I cannot help but imagine pure space with nothing, being taken up by the expanding universe with its stars, galaxies, energy, masses, gases, atoms, etc.It is difficult to imagine. Creating true space as it expands, is a strange concept.Edited by jaywill, : No reason given.Edited by jaywill, : No reason given.

I thank you for three paragraphs of explanation. And I will read them again carefully.But, I do not understand what you are saying.As for Einstien's Theory of General Relativity, I suspect there are a small handful of people on the planet who can claim to REALLY understand it inside out.I ain't one of them.OKay, maybe a lot more people can claim to REALLY understand it inside out.But cosmology does fascinate me and always has.I will say that I am not sure if infinity in a practical sense really exists. I could be wrong. But at present I think infinity maybe only exists in the mind as a concept.Now, I am going to go back and read your post another time.Edited by jaywill, : No reason given.

CD,This is addressed to you. Anyone can answer though. In the last sentence, I have difficulty seeing the difference between the two ideas.I think I also may contradict myself when I say infinity in a practical sense may not exist. But this vacuum or whatever beyond the two farthest "things" as you called them, well that may be the only infinity.I mean the two "things" with the biggest number discribing how far one is from the other.What are your thoughts on these two questions?1.) Years ago someone told me that if you travel in the universe in one direction long enough you will come back to the same place you started.Is that an accepted concept ?2.) Many things in the universe are rotating. Do you think that the whole universe may be rotating also ?]Edited by jaywill, : No reason given.
