I think you are wrong about this. It does make space more dense.
From this article about metric expansion of space https://en.wikipedia.org/wiki/Metric_expansion_of_space
It is an intrinsic expansion whereby the scale of space itself is changed. That is, a metric expansion is defined by an increase in distance between parts of the universe even without those parts "moving" anywhere.
That is the same as making space more dense. If it is not the same, explain why you think that.
Edit:
Imagine the fabric of space as a chess board and there is a black rook in the center of the board. Instead of being able to move as many spaces horizontally or vertically on the board per turn, you can only move 1. You cannot move diagonally. Your rook has a clock on top of it. This clock can tick once per turn, but you can't move the rook and tick the clock in the same turn.
Now imagine a second, white, rook on the same board near the black rook. This white rook is light and it has no clock. The two players don't have to take turns moving, but they have to take their turns simultaneously. The black rook cannot take a turn unless the white rook takes a turn and vice versa.
The white rook, being light, will always move in the same direction 1 space every turn.
If the black rook were to do the same, the clock would never have a chance to tick, thus time would appear to stand still. The black rook would also be moving at the speed of light.
If the black rook were to alternate a move and a clock tick during every turn, it would be traveling at half the speed of light and the time reading on the clock would increase by 1 second per every 149,896,229 meters it moves.
If we add a red rook to the table that decides to spend 3/4 of its turns ticking its clock and 1/4 moving in the same direction as the white rook, then it would be moving at 1/3 the speed of light and the time reading on the clock would increase by 1 second per every 74948114.5 meters it moves.
This is how everything in the universe works. Nothing can move in more than one direction in space at one time. With no other force acting upon it, light spends all of its turns moving in the same direction and doing nothing else, so it is the fastest moving thing in the universe.
Now, lets apply gravity to the mix. Now each rook has to spend 1/2 of its turns moving towards the source of the gravity leaving the black rook only 1/4 of its turns to tick its clock and 1/4 moving, the red rook only 1/8 ticking it's clock, and 3/8 moving, and the white rook 1/2 of it's turns moving. Now it appears that gravity has slowed down time according to the clocks on the black and red rooks.
Since the distance between the two points doesn't physically change, in order to get those extra squares devoted to the force of gravity into the same "space", the squares must be compressed to allow room for these new ones, thus increasing the density of space.
Edit: I actually just thought of this "Nothing can move in more than one direction at a time" concept today, but I believe it to be 100% true and the reason we observe the things in General Relativity.
