Quote:
Why is the universe expanding at an ever-increasing rate? This is one
of the most exciting yet unresolved questions in modern physics.
Because it cannot be fully answered using our current physical
worldview, researchers assume the existence of a mysterious "dark
energy." However, its origin remains unclear to this day.

An international research team from the Center for Applied Space
Technology and Microgravity (ZARM) at the University of Bremen and the
Transylvanian University of Brașov in Romania has come to the
conclusion that the expansion of the universe can be explained—at
least in part—without dark energy.

It would be neat if the fudge of adding 'dark energy' is not needed.
