Seminar: Exploring Nature with Black Holes and Gravitational Waves

ABSTRACT

In this talk, we will explore the exciting world of black holes and gravitational waves and their role in our understanding of the universe. First predicted by Einstein's theory of general relativity over 100 years ago, the detection of gravitational waves by the Laser Interferometer Gravitational-Wave Observatory (LIGO) in 2015 and the first-ever image of a black hole captured by the Event Horizon Telescope (EHT) in 2019 have ushered in a new era of astrophysics. We will discuss how black holes and gravitational waves allow us to probe gravity in the uncharted strong-field regime and the behavior of matter under extreme conditions. I will elaborate on how my research capitalizes on these compelling objects as modern and effective tools to study the laws of nature.

 

BIOGRAPHY

After receiving his PhD from HKUST in 2017, Dr. Sam Wong received the Croucher fellowship and pursued a postdoctoral position at Columbia University. Since 2019, he has continued to delve into the mysteries of black holes and the early universe as a postdoctoral fellow at the Center for Particle Cosmology at the University of Pennsylvania.

Dr Wong’s research interests are diverse but all focused on probing the fundamental laws of nature. He aims to contribute to the advancement of their field by investigating the structure of black holes and the earliest moments of the universe's existence, with the hope of uncovering new insights and expanding our knowledge.
