Because new matter is not created. What is here is all you get although it gets further and further apart as we speak. And our universe will end when the combined gravitational force slows the expansion and begind compressing all matter back into one tiny speck of dust only to explode again.

As matter can be converted to energy E= MC^2, the mass cannot be constant. The sum of the two may be due to principles of conservatism.
I don’t think anybody has a definite answer as 95% of the universe is still the unexplained dark matter or dark energy

I don't know that the universe extends to infinity, but mass and space are two differnt things so something can grow in the space it takes up (volume) and not increase in mass.
If Volume increases without mass increasing then denisty decreases.
If Mass Increases without Volume increasing then denisty increase.

the matter does not remain constant.energy and mass are interconvertible.actually there is a lot more matter in the universe than we can see or detect(earlier called ether).universe is one,continually expanding.

It's like putting a gallon of paint into a five gallon bucket.

Because energy cannot be created or destroyed....It's the law.
