Why there is no dark matter?

In numerical simulations attempting to explain the rotation of galaxies something was not right. The physics used was Newtons mechanics! Can you believe that?

To fix the problem they had to consider that there was more matter in a given galaxy than that detected from earth. But the extra matter used in the calculations was not observed. For this reason, it was supposed to be ‘invisible’ – the term ‘dark’ is not adequate.

Why the conclusion was wrong?

The reason is that the physics used to describe the motion of such large masses (stars) should be Relativistic (special or general.) Using relativity, the motion of the stars will generate something analogous to the magnetic field, the gravitomagnetic field, that acts on moving matter. Using this approach, the rotation of several galaxies have being explained, without requiring the concept of dark matter.
