Difference between Impenetrable and Dense

IMPENETRABLE vs DENSE: NOUN

Incomprehensible; inscrutable.
Not penetrable.
Inaccessible, as to knowledge, reason, sympathy, etc.; unimpressible; not to be moved by arguments or motives.
Not admitting of penetration or passage into or through
Permitting little if any light to pass through because of denseness of matter
Impossible to penetrate or enter.
Impossible to understand; incomprehensible.
Having the property of preventing any other substance from occupying the same space at the same time.
Incapable of being penetrated or pierced; not admitting the passage of other bodies; not to be entered; impervious.
Impervious to sentiment or argument.
Impossible to understand

Slow to learn or understand; lacking intellectual acuity
Permitting little if any light to pass through because of denseness of matter
Hard to pass through because of dense growth
Closely crowded together
Having high relative density or specific gravity
Of a person, slow to comprehend; of low intelligence.
Being a subset of a topological space that approximates the space well. See Wikipedia article on dense sets for mathematical definition.
Obscure, or difficult to understand.
Opaque; allowing little light to pass through.
Thick; difficult to penetrate.
Compact; crowded together.
Stupid; gross; crass.
Slow to apprehend; thickheaded.
Difficult to understand because of complexity or obscurity.
Opaque, with good contrast between light and dark areas. Used of a photographic negative.
Permitting little light to pass through, because of compactness of matter.
Hard to penetrate; thick.
Crowded closely together; compact.
Having relatively high density.
Having the constituent parts massed or crowded together; close; compact; thick; containing much matter in a small space; heavy; opaque

Specifically, in physics, having the property of preventing any other substance from occupying the same place at the same time.
Incapable of being penetrated; not penetrable, in any sense of that word.

In optics, having a large index of refraction; capable of transmitting light at a less velocity than the velocity of light-waves in vacuo.
Having great or unusual consistency of elements or closeness of parts; closely compacted or conglomerated; compact; close; thick: as, a dense body; a dense cloud or fog; a dense panicle of flowers.
In zoology, closely set; separated by very small intervals: as. dense punctures, hairs, etc.
In photography, more or less opaque; strong in the contrast of lights and shades: said of a negative exhibiting these characteristics, and capable of giving a brilliant print, or even, if it be too dense, a harsh one, as distinguished from a weak or thin negative, the picture on which presents small contrasts, while its film is inclined to be more or less transparent, even in the lights, and the resulting print is flat. Also expressed by strong and intense.
Figuratively, without break or interruption; difficult to penetrate; solid and heavy: as, dense ignorance; dense wit; dense stupidity.
Thick-headed; obtuse; stolid; stupid; dull.
Synonyms Condensed, compressed.
Lacking intellectual acuity
Having component parts closely crowded together
Slow to learn or understand
