For constant w = −3/2, the Milky Way will get stripped roughly 60 million years before the Big Rip. Curiously, when this occurs the horizon will still be ~ 70 Mpc, so there may still be other observable galaxies that we will also see stripped apart (although given the time delay from distant objects, we will see the Milky Way destroyed first). A few months before the end of time, the Earth will be ripped from the Sun, and ~ 30 minutes before the end the Earth will fall apart. Similar arguments also apply to objects bound by electromagnetic or strong forces. Thus, molecules and then atoms will be torn apart roughly 10−19 seconds before the end, and then nuclei and nucleons will get dissociated in the remaining interval.

It will be necessary to modify the adopted slogan among cosmic futurologists - "Some say the world will end in fire, Some say in ice" - for a new fate may await our world.
