Dr.
Nesbet will describe (in layman's terms) implications of a theory that
differs from standard particle physics and cosmology only by imposing a
universal symmetry principle. This theory has been found to explain dark
energy and dark galactic halos without invoking dark matter.
Subgalactic phenomenology (relevant to our solar system) is retained.
The
model postulates that strict conformal symmetry (local Weyl scaling
covariance), already satisfied by standard fermion and gauge boson
theory, can be extended to all elementary massless fields. This modifies
Einstein-Hilbert general relativity and the Higgs scalar field model.
No new physical fields are introduced.
Dr. Nesbet will show that
conformal gravity and a conformal Higgs model fit empirical data on
galactic rotational velocities, galactic halos, and Hubble expansion
including dark energy. By implication, dark matter is not needed for an
isolated galaxy. This model appears to be a promising tool for
understanding both cosmology and elementary particle physics.
