If dark matter constitutes the vast percentage of the universe, why is it
not found all around us?

We don't know if dark matter exists on Earth around us.
We only find it indirectly between galaxies because its mass.

I think most conceptions of dark matter assume that it IS all around us.

Nigl, there are amny such questions or phenomena. See one below
................==
Einstein speculated E =mc2 from L =mc2 in Sep. 1905 : Ajay Sharma

Einstein did not derive E=mc2 in 1905 , but speculated it from Light
energy mass equation L =mc2. In derivation of L=mc2 Einstein used
equation

l* = l{1 – v/c cos φ } /√[1 – v2 /c2]

which he has given in June 1905 paper.
Using this as central equation Einstein obtained equation
L=mc2 (1)
under special conditions (when emits TWO light wave, of equal MAGNITUDE
, exactly in opposite directions , relative velocity v is in classical
region ).
Then Einstein replaced L (light energy ) by E (( every energy i.e.
light energy, heat energy ,sound energy , electrical energy , energy in
form of invisible radiations etc ) and thus SPECULATED
E=mc2. (2)
Such an important equation ( INTER CONVERSION OF MASS –ENERGY ) should
have valid and well defined derivation.
When it is done then result is
dE =Ac2 dm
when A is coefficient of proportionality like numerous existing in
physics.

good question. some critics think people are doing bad experiments, and
then grasping at straws to explain the numbers.

i don't know what the answer is, but i think we need to focus more on
particle accelerators and scribling in notebooks.
