Satellite galaxy orbits versus cold dark matter

Observed orbits of satellite galaxies around host galaxies continue to be inconsistent with simulations based on the Lambda Cold Dark Matter (ΛCDM) model. Mainstream scientists believe that approximately a quarter (25%) of the Universe is made of an invisible and as-yet detected substance called “dark matter”.  Dark matter supposedly explains not only the rotation of stars within galaxies but also the rotation of satellite or “dwarf” galaxies around other larger host galaxies.  According to the […]
