The universe is expanding at an accelerated pace because of "dark energy." Scientists hypothesize that 100 billion years from now all the distant galaxies that you can currently observe will disappear from our sky. This is because they will have separated from our galaxy at such an accelerated rate of speed that their expansion will be faster than the speed of light (space can expand faster than the speed of light). In this distant future time, astronomers would have no reason to conclude or suspect that other galaxies exist, or even that the universe is (at that time) still expanding, unless they had access to the preserved cosmological knowledge of our time.
Some objects once visible at half the universe's current age of about 13.7 billion years are already invisible from the farthest vantage points.
In the potentially infinite future, if the density of dark energy increases to approach infinite dimensions, its gravitational repulsion could rip apart all the objects in the universe--even matter itself. Not only will galaxies disappear, but individual molecules could be ripped apart by the gravitational acceleration of the dark energy which could eventually overcome the forces holding molecules together. No object would escape this fate. Eventually, the universe could be nothing but empty gas atoms moving between an ever expanding space: the ultimate dissolution.
In the end, nothing may go together.
