Big Rip Singularity Information P. F. González-Díaz, astro-ph/0507714, Grav. Cosm. 12, 29 (2006); Phys. Lett. B 635, 1 (2006). Allowed Paths circumventing the Big Rip Singularity sent to infinity
Everything, including an advanced future civilization, will be able to perform a big trip so escaping or circumventing the big rip. There is no problem with the Bekenstein’s Information/Energy bound.
