Galaxy Sans Dark Matter

Posted by samzenpus on from the nothing-extra dept.

ChromaticDragon writes "Astronomers have crunched some numbers on a galaxy to discover that its rotation can be fully explained by the gravity of the observable matter — in effect, this galaxy seems to lack dark matter. This shouldn't come as a total surprise given that one of the stronger observations of Dark Matter was the Bullet Cluster where supposedly a good deal of Dark Matter and good old fashion regular matter had separated."

    The trend in physics for the past 30 years has been to invent a new particle to explain any discrepancies with current theory anyway. This is no surprise.

    This is another nail in the "dark matter can be solved with a modified theory of gravity" coffin. If we can find a galaxy composed of stars whose observed motion is entirely explained by the mass of those stars and known theories of gravity (Newton, Einstein) that's a serious blow to theories like MOND.

    Im with the string theory people and what we are seeing is an "effect" of multidimensional space.

    The only thing String Theory people see are grant cheques. ST must surely be the least successful scientific theory of all time in terms of the effort put in versus the results got out.

    It's just a way for the editors to abrogate their responsibilities while blaming the users when crappy submissions get posted.
