" And I looked when He broke the sixth seal, and there was a great earthquake; and the sun became black as sackcloth made of hair, and the whole moon became like blood; 13 and the stars of the sky fell to the earth, as a fig tree casts its unripe figs when shaken by a great wind. 14 The sky was split apart like a scroll when it is rolled up, and every mountain and island were moved out of their places.…"===Revelation 6:12
Well, advanced super artilects of our own creation, long after the extinction of fleshly humans, will have plenty of time to work out this problem if they don't want to be circling the drain in 22 billion years.
"A universe dominated by phantom energy expands at an ever-increasing rate. However, this implies that the size of the observable universe is continually shrinking; the distance to the edge of the observable universe which is moving away at the speed of light from any point moves ever closer. When the size of the observable universe becomes smaller than any particular structure, no interaction by any of the fundamental forces (gravitational, electromagnetic, weak, or strong) can occur between the most remote parts of the structure. When these interactions become impossible, the structure is "ripped apart". The model implies that after a finite time there will be a final singularity, called the "Big Rip", in which all distances diverge to infinite values.
The authors of this hypothesis, led by Robert Caldwell of Dartmouth College, calculate the time from the present to the end of the Universe as we know it for this form of energy to be
t_{rip} - t_{0} \approx \frac{2}{3|1+w|H_0\sqrt{1-\Omega_m}}
where w is defined above, H0 is Hubble's constant and Ωm is the present value of the density of all the matter in the Universe.
In their paper, the authors consider an example with w = −1.5, H0 = 70 km/s/Mpc and Ωm = 0.3, in which case the end of the Universe is approximately 22 billion years from the present."
