One of the criticisms the new paper levels at standard cosmology is that the conclusion that the Universe is accelerating is model dependent. That's fair enough. Usually cosmologists are careful to say that we are studying 'dark energy', which is the name we give to whatever is causing the apparent acceleration of the expansion of the Universe.

Although the extent of the observable Universe, today ...
If the force of expansion were much, much stronger than it is, then even gravity might not be able to pull galaxies together, and each galaxy really would be an island universe, isolated for all time.Nov 13, 2014 · The idea was that the Universe received all the energy it needed for its expansion in the first few moments after the Big Bang. Imagine the beginning of the Universe, BOOM, like an explosion from ...
If the Universe is expanding today, that means it was smaller, hotter, and denser in the past: leading to the picture of the hot Big Bang.
