While gravity is a force that attracts objects with mass, dark energy (or, alternatively, the accelerated expansion of the universe) is not.

However, I have found numerous articles, forums, questions in the stack exchange network... where people seem to say that if you get further from a gravitational source (e.g. a galaxy) there would be a point where the influence of gravity (attractive) and dark energy (repulsive) would be balanced out (sometimes even using the term "force").

But again, dark energy is not a force (as said in here and also here). So what is happening here? Is there such a point? If not, then, why are there so many people saying that there is? This is confusing...

PS: Examples of people mentioning a point where there is a balance between Dark Energy and gravity:

Is there a distance from a gravitational source where the influence of gravity and dark energy are balanced out?
