The toatal quantity of energy-mass in the universe is always the same. However, mass is not getting scarces, just less 'concentrated'. The current overall density of the universe is about the equivalent of 5.9 hydrigen atoms per 1 cubic meter.

First, there is a popular balloon analogy of which I feel directly applies to this. Say for instance you are a 2D creature on the 2D surface of a balloon. Your balloon world is continually getting bigger, hence the expansion. Some god like being of a higher dimension is blowing hot air, a gas, into the balloon. You do not see he expansion, literally, but you can observe a few oddities about your world.
Secondly, objects on your world do seem to be moving away from each other. A dot on your side of the balloon is taking more time to reach on the other side with each passing moment. In this analogy, objects are indeed getting bigger as well. As the surface expands with air, so does the object or picture you drew on the surface. Wouldn’t is seem to mean that there is more space between particles of the balloon’s surface and the object on it?
Thirdly, you may notice that a perfectly round balloon might have an almost perfect curvature to its surface. Thus, you could say that you universe had a uniform curvature and when someone pushes on the surface and makes a dimple, that would seem to be a gravity point and would pull you in. Our own universe is said to have curvature as well.
Finally, to make matters short, couldn’t we inhabit a 3D world on the surface of a higher dimensional balloon world which was blown up by some high being? If you keep blowing up the balloon, it would inflate at a slower rate the bigger it gets. You could say bye-bye world if it gets so big that it could explode. Also, you could lose the power to keep blow it up and it would get away from you and rapidly deflate. This could be a reverse big bang.
Without going much further in this line of thought, I will stop here. I read books along these topics instead of regular novels. So, are we all getting bigger and moving away from each other, proportionately, or is the balloon just full of hot air?

It's F=MA not F=MV.In order for an object to maintain a constant velocity it must continually accelerate.This means that the object must be powered or fueled somehow.The electron travels at a constant velocity so it is continually accelerating.This means that the electron and the atom must have a power source.The Cartesian junction is the center of all things that spin,everywhere,every when,all places all at once.At the Cartesian junction is the exact center of all atoms and the Big Bang point.If the universe were getting bigger without a power source you might detect a change in the velocity of light.There would have to be a ever welling power source to power all atoms.The universe could expand and its mass could increase without a problem

The amount of mass in the universe always stays constant. Most of the universe now is a near perfect vacuum.

Gravity/mass is the only constant that connects through the 11 dimensions in the latest theories that dictate each dimension is only a membrane about 1 mm apart from each other.
I envision expansion in one dimension but balanced out by contraction in the others.
Think of yourself floating in the ocean... as a wave of water goes past you lifting you (one dimension) and lowering your friend a few meters away (the other dimension).
Therefore I believe that the mass is the same.

The density of matter in the universe is getting less, which I guess is what you mean by matter getting scarcer. So, yes, it is getting scarcer or less dense.

Uh, the previous answer about constant mass?...E=mc^2?...mass is not constant...
ok to answer your question... the density of the universe is decreasing but the real question is how much is it decreasing by? Is it decreasing by the same percentage of universe volume is increasing? that is a tougher question.

Entropy.
Matter is becoming more diffused. More scattered.
Except where it isn't.
Things fly apart.
But planets and suns "coalesce" from gas clouds?
The dispersion of matter and energy tends towards the maximum, but it doesn't.
Gravity is contrary to entropic forces?

Most of the mass of universe is ...'somewhere else', possible in 10 or 11th dimensional space.
these are possible with mathematical/thoeretical physics.

The amount of "space" in between gets larger, not the objects themselves.
