Dark Matter in the Universe?

  • Barry Parker


We have seen that there is dark matter both in clusters of galaxies and in individual galaxies. But galaxies are part of the overall universe. Does this mean there is a dark matter problem there also? There is, indeed, an enigma in relation to the universe, but it may or may not be related to the dark matter of galaxies. Some of the universe’s matter appears to be missing, so in this case we may have a real missing mass problem. In the case of galaxies and clusters the mass isn’t missing; we have strong evidence that it’s there. We just don’t know what form it takes.
