Well in another blow to standard model cosmology, a recent study by the Europeans has found no dark matter, none, where some must be if current models/predictions are true.  This has profound implications on current theories, specifically with gravity!


The blue “halo” is meant to represent the dark matter surrounding our galaxy and basically ‘holding it together’ since we seem to not have enough visible matter to make the whole thing work, gravitationally speaking.   I should not have to say this, but I will.  This is NOT a picture, there are no pictures of our Galaxy.  You would have to be 100,000 thousands of light years away to get such a picture.  This should be self explanatory, but for many it is not.  Sorry for the rant.

The amount of mass that we derive matches very well with what we see — stars, dust and gas — in the region around the Sun,” says team leader Christian Moni Bidin (Departamento de Astronomía, Universidad de Concepción, Chile). “But this leaves no room for the extra material — dark matter — that we were expecting. Our calculations show that it should have shown up very clearly in our measurements. But it was just not there!

The above statement is confronting (although it sounds straightforward enough), because of the following standard scientific belief:

Today it is widely accepted that this dark component constitutes about the 80% of the mass in the Universe [1], despite the fact that it has resisted all attempts to clarify its nature, which remains obscure. All attempts so far to detect dark matter in laboratories on Earth have failed.

By very carefully measuring the motions of many stars, particularly those away from the plane of the Milky Way, the team could work backwards to deduce how much matter is present [2]. The motions are a result of the mutual gravitational attraction of all the material, whether normal matter such as stars, or dark matter

And this leads to this conclusion:

Despite the new results, the Milky Way certainly rotates much faster than the visible matter alone can account for. So, if dark matter is not present where we expected it, a new solution for the missing mass problem must be found. Our results contradict the currently accepted models. The mystery of dark matter has just become even more mysterious. Future surveys, such as the ESA Gaia mission, will be crucial to move beyond this point.” concludes Christian Moni Bidin.

Personally, I would look elsewhere…. Say the black hole at the center of the Galaxy and it’s effects on the matter around it.  Perhaps gravity is not what it appears!  Doh!

And in classical denial (not the river in Egypt), what some scientists have to say:

"We have many independent lines of reasoning that lead us to the conclusion that we have substantial amounts of dark matter in the local part of our galaxy," says Hooper. "This is not going to be easily abandoned as an idea. I’m not saying they’re wrong, just that you’re going to have to work really hard to convince me."

So in this ‘standard model’ being defend so vigorously here:

In the standard view, dark matter drew together under its own gravity to form small clusters shortly after the big bang. Those clusters snowballed in size, and galaxies as we see them today grew up inside massive, near-spherical haloes of dark matter.

If that were true, the streams of stars, clusters and small galaxies that orbit the Milky Way should be distributed randomly in a sphere around the main disc. But Kroupa reports in a paper to be published in Publications of the Astronomical Society of Australia that most of them are clustered in an enormous disc that rotates in a plane perpendicular to that of the Milky Way.

I don’t actually need to read a paper to know that.   Every fifth grader knows that, so they must explain what we can see clearly in our night sky as:

That disc could be the remnants of another galaxy that collided with the Milky Way some 11 billion years ago, but it could not be the result of dark matter, Kroupa says.


They really do work hard to defend a position once taken, no matter what the onslaught of facts and readers of scientific materials should ALWAYS keep that in mind.  Now, back to whatever it is you were doing before coming here!
