I don't believe communication and travel are any problem for Gods. They can do that and still have all the closeness they desire.

SHORT ANSWER: It doesn't appear that they can be together for eternity. LONG ANSWER: A common question asked by members is whether it is possible for someone to eventually move from Telestial to Terrestial glory, or, relatedly, from Terrestial to Celestial glory. Some even compare it to wheels on a train. You may get where someone ahead of you was before, but they will always be ahead of you. General Authorities Bruce R. McConkie (in Seven Deadly Heresies), Spencer W. Kimball (in Miracle of Forgiveness), and Joseph Fielding Smith (in Doctrines of Salvation) have stated that once someone is within a kingdom of glory, that person remains within that kingdom for all eternity; no one can advance out of a kingdom. Many general authorities do speculate that there is advancement within kingdoms, though. http://www.mormonwiki.com/Celestial,_Terrestrial,_and_Telestial_Kingdoms

We mere mortals are incapable of understanding all of the ways of God. So, no matter how much He reveals to us, there will always be more questions. That written, I have to agree with edndor. What is space to a deity. However it is arranged, I very much doubt that there will be any problem with family members being able to meet with each other whenever they want while they are going about whatever else they are doing.

"I don't believe communication and travel are any problem for Gods. They can do that and still have all the closeness they desire." First, this question makes me chuckle... He He He This is just one of the many many absurd contradictions Joey didn't plan for. If he were not killed by fellow Free Masons, he would be having new Revelation to change this impossibility. The comment quoted above, is from an LDS. I wonder how they can have it both ways on so many issues. They say god can not be all places at all times, yet that is what that statement says. And, if they are having a hump fest for eternity, how is there time to be all places at once. They also will have to be answering all requests from there planet inhabitants. I wonder, will they have an Adam and Eve? Will there planet have a Joey Smothers? Will they just dump Mormonism out there for the peoples? If Joey is correct, has it taken this long to get it right with the gods? Are all the worlds that have been populated with Mormon babies, are they all Mormon exclusive? Since this planet has gone through so much to perfect Mormonism, why would all future planets not just adopt this curriculum?

Together for eternity needn't mean all living under the same roof. I personally would rather hope such is NOT the case...

I couldnt think of anything better to do for eternity then see the whole universe.
