Some think that this is could be responsible for the universe expansion. The reason is if you try to go beyond the right side of the formula and the M is the mass of the universe and she can't be change the only thing it can change is the L or in this case the radius of the big bang event (R). So in order this formula to be true radius must increase. If this is happening with time this will look like expansion. This is where gravitational force comes. This formula needs a force which will compress the mass with time so the linear density to try to go beyond the right side of the formula. It's little hard for me to explain because i don't understand very well.
