Something’s Just Not Right with our Current Understanding of Dark Matter
Dark matter does not emit, absorb, or reflect light. Its presence, if it truly exists, is known only through its gravitational pull on visible matter in space. This mysterious substance is believed to be the invisible scaffolding of our Universe, forming long filamentary structures -- the cosmic web -- along which galaxies form. Astronomers have discovered that there may be a missing ingredient in our cosmic recipe of how dark matter behaves. They have uncovered a discrepancy between the theoretical models of how dark matter should be distributed in galaxy clusters, and observations of dark matter's grip on those clusters. One way astronomers can detect dark matter is by measuring how its gravity distorts space through an effect called “gravitational lensing.” Researchers have found that small-scale concentrations of dark matter in clusters produce gravitational lensing effects that are ten times stronger than expected. This evidence is based on unprecedented detailed observations of several massive galaxy clusters by NASA's Hubble Space Telescope and the European Southern Observatory's Very Large Telescope (VLT) in Chile.

I totally agree with your observation.
New work like that described in this posting is beginning to point to a very inconvenient conclusion -- The two entities of Dark Matter and Dark Energy may not actually exist. They may be just imaginary concepts.
History provides us with many examples where scientists have simply invented ideas out of thin air to help explain away things that are just not understood.
In some ways, Dark Matter and Dark Energy bring to mind another imaginary concept -- the so called "Aether Wind" of the 1800s. Back then, everybody just "knew" that space was filled with an "Aether Wind." The problem was that no one had ever seen it. Nor had they measured it.
In 1887, Albert Michelson and Edward Morley set out to prove the existence of Aether Wind once and for all. Their experiment failed spectacularly in its attempt to detect any Aether Wind, but in the process they showed that the whole concept of Aether Wind, which most scientists at the time simply accepted as fact, was flawed -- There was no such thing.
Michelson eventually won the Nobel Prize in Physics in 1907 for this work and became the first American to do so.
New exploratory work like this may eventually lead to the development of a modern-day version of a Michelson-Morley-like experiment where the whole concept of Dark Matter and Dark Energy, which most scientists today accepted as fact, is shown to be flawed.
In the end, there may be no such thing.

Our Big Bang may NOT have originated at the center but from the outside
beyond 13.7 billion light-years analogous to a Supernova generating a Black Hole.
The predicted Schwarzschild radius for our observable universe is 13.7 billion light-years.
Are we living in a black hole? We need another Einstein to advance our understanding of gravity.
As always I may be wrong again.
