The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Using solar system measurements, we are able to derive limits on the timescale for a future big rip independent of the dynamics of the phantom component. We obtain t_rip - t_0 > 30 years.

C2weakest assumption

Solar system dynamics are sensitive to the behavior of phantom dark energy on timescales of decades rather than billions of years.

C3one line summary

Solar system measurements set a lower bound of 30 years on the time until a possible Big Rip from phantom dark energy.
