It is also possible that the galaxies will ont slow down quick enough for this to happen, and will be too far apart to pull back together. In that case, everything will die out and the entire galaxy will reach a rather boring and cold thermal equilibrium.Shadowy Fear said:Yes, good job to all three of you
Btw, though, the universe is NOT forever - at least OUR universe, for whatever that is worth.
Galactic expansion is slowly, but steadily (like evolution ) slowing down. Eventually, gravity, although it is the weakest force in the known universe, will completely stop galactic expansion, and then reverse it, so that the galaxies are mvoing TOWARDS each other. Finally, they will all be pulled together, along with the 'rest' of the universe, and collapse into an ultramassive black hole; Omega Point, the end of the universe. Then, there are sevral theories about what happens next ('universe' traveling through wormhole and creating new universe, big bang all over again, etc.).
I think it is fair to say that the Earth and any information on it will be lost forever.
