There is no more accurate descriptions of matter than measurements. To get the description right make your measurements precise.
Yes. It stands for: Weakly Interacting Massive Particles.
It provides universally accepted quantities for measurement. For example, a mile is always the same length no matter what country you're in.

Biased measurements can be corrected by using an unbiased subject in which results are produced from. That is to say that by using a broader subject matter the results will be less favorable to the required or suggested result and will produce a more accurate result.
A description of the universe includes all matter and energy.
It is a matter of scale.
Matter has MASS, and takes up SPACE.
The least accurate description of molecules would be to define them solely as "tiny particles that are always in a solid state." This description fails to account for the various states of matter (solid, liquid, gas) that molecules can exist in, as well as the diverse range of molecular structures and interactions. Molecules are actually groups of atoms bonded together, which can exhibit different behaviors and properties depending on their composition and environment.
Because a submicroscopic description of matter is part of the theories of chemistry and provides explanations for macroscopic phenomena and chemical reactivity - and these theories provide a means for us to apply chemistry, using it to predict other macroscopic phenomena.
Matter is anything that has mass and takes up space
You are probably talking about "grey matter" ("gray matter"). This is just a fancy description of "brains".
Measurements of the present density of the universe are crucial for understanding its overall composition and evolution. They help determine the proportions of dark energy, dark matter, and ordinary matter, which influence the universe's expansion rate and ultimate fate. Accurate density measurements also provide insights into fundamental cosmological parameters, aiding in the verification of theoretical models like the Big Bang and inflation. Ultimately, they enhance our understanding of the universe's structure and the laws governing it.
