Dark matter blob confounds experts

The quest to find DM exist for many decades unsucessfully, and it's existence rooted deeply in our heads. I remind that DM and DE are, in their inception, hypotetical entities. It seems to be be forgotten by all.
There are other theories because DM & DE are subject of intense speculation.
But all of them appeal to more untested, if testable, strange entities, like multiverses or other dimensions, or MACHOS, WIMPs, etc.
The physical tests for detection had null results, inspite of, according to prevalecent theory, we have to be immersed in DM & DE.
If DM exists then why the Solar System has no trace of it? The Sun should have grabbed some of it to it's surroundings. But there is not a single clue that DM exists (i.e forming a gradient in mass) in the Solar System.
In this PSE-post I explain why I'm confident that there is no need of DM nor DE to explain the universe evolution.
In galactodinamycs there is more to consider than a central force, for instance:
find where are the neibourough voids wrt the Milky Way (*), and also conclude that the voids are inevitably growing.
(*) I'd appreciate if anyone around intends to check that they are in the opposite direction wrt to the direction of the Great Atractor, as I beleive, or whatever other direction. Any reference to data that shows that the voids are growing is appreciated. Downvote with quality, find papers with data.
