"If the work of dark energy were constant over time, it would eventually
push all the stars and galaxies so far apart that even atoms would be
torn asunder,..."
That's not true. The estimated strength of dark energy, w=-1, implied
that galaxy clusters and any smaller groups would still be held together
by gravity, to say nothing of EM and nuclear forces.
Still an interesting. The next question will be what causes DE to
change? When it was just the cosmological constant there was no change
to be explained.
