Title:
Is dark matter fact or fantasy? -- clues from the data
Abstract:
We discuss the arguments both in favor of and against dark matter. With the repeated failure of experiment to detect dark matter we discuss what could be done instead, and to this end look for clues in the data themselves. We identify a contribution to galactic rotation curves coming from the rest of the visible Universe, and suggest that dark matter is just an attempt to describe this global effect in terms of standard Newtonian gravity within galaxies. Thus the missing or dark mass is not missing at all -- it has been hiding in plain sight all there along as the rest of the visible mass in the Universe.
About Particle Physics Theory seminars
The Particle Physics Theory seminar is a weekly series of talks reflecting the diverse interests of the group. Topics include analytic and numerical calculations based on the Standard Model of elementary particle physics, theories exploring new physics, as well as more formal developments in gauge theories and gravity..
