Michael Shay and collaborators find surprising event in turbulent space
Scientists have discovered an entirely new magnetic phenomenon in the outer reaches of Earth’s magnetic field with the help of four NASA spacecraft, according to a new study published in the journal Nature.

A new partnership with the Southeastern Association for Research in Astronomy (SARA) gives researchers and stargazers from the University of Delaware and nearby Mount Cuba Astronomical Observatory access to three far-flung telescopes and the superior perspectives they offer on the night sky.

We discuss how the S-matrix formulation of quantum gravity eliminates de Sitter vacua, both stable or meta-stable. The S-matrix constraint is enforced by the phenomenon of anomalous quantum break-time. This also puts an upper bound on the duration of inflation and points to new potentially-observable quantum gravitational imprints. In this way, through its S-matrix formulation, quantum gravity/string theory nullifies an outstanding cosmological puzzle and excludes the cosmological constant from the energy budget of our Universe.
Dr. Shu received his Ph.D. in 2014 for the studies of low temperature surface passivation of crystalline silicon and its application to interdigitated back contact silicon heterojunction (IBC-SHJ) solar cell under the supervision of Prof. BIrkmire. Dr. Shu is now a staff engineer at Western Digital, CA.
Contributions to the University of Delaware may be designated for a particular Department. Gifts help us support activities that would be difficult to fund from our regular budget, such as scholarships, graduate and undergraduate student awards, support for students to travel to conferences, and outreach programs.
