No evidence of that claim, of course.

As the universe expands and galaxies move farther from each
other, the gravitational potential energy of the universe
actually increases.

If there is such a thing as dark energy, dark energy gets
converted to mechanical energy (motion of the galaxies),
and that gets converted to gravitational potential energy
as everything gets farther away from each other.

If there is no "dark energy", the first step is skipped, and
residual energy of motion becomes gravitational potential
energy.

If the universe is "closed" this potential energy becomes
mechanical energy of motion again and then who knows (big
crunch?).

If not, I don't see a mechanism for this energy to ever become
thermal energy in the infinitely cooling universe.
