Sandi Setiawan Launches Groundbreaking Dissertation on Geometric Algebra and Black Holes

Sandi Setiawan, renowned astrophysicist and expert in theoretical physics, is proud to announce the release of his dissertation titled Applications of Geometric Algebra to Black Holes. This groundbreaking work, presented for the degree of Doctor of Philosophy at the University of Cambridge, provides an innovative exploration into the role of geometric algebra in the study of black holes.

Drawing on advanced concepts in physics, Setiawan’s dissertation provides a new framework for understanding the behavior of black holes in terms of geometric algebra, an area of mathematics that extends traditional algebra to geometric objects. This work pushes the boundaries of theoretical physics by unifying different mathematical languages and offering new insights into gravity, cosmology, and quantum mechanics.

Setiawan's research covers several key areas:

  • Geometric Algebra: A detailed introduction to geometric algebra, explaining how it can unify various branches of mathematical physics and improve our understanding of fundamental interactions.
  • Gravity as a Gauge Theory: The dissertation presents a novel perspective on gravity, describing it as a gauge theory, which brings a fresh understanding of gravitational interactions.
  • Black Hole Thermodynamics: A discussion of relativistic wave equations and the Hawking temperature in the context of Schwarzschild and Kerr black holes, challenging established assumptions in the field.

"I am thrilled to share my research with the scientific community. This dissertation represents years of work aimed at bridging gaps in our understanding of black holes and the mathematical tools used to study them," said Sandi Setiawan.

Setiawan's work was conducted under the guidance of Dr. S. F. Gull, with contributions from Dr. C. J. L. Doran, Dr. A. N. Lasenby, and other leading experts. His research has received support from prestigious institutions including Clare Hall, Cambridge Overseas Trust, and the British Council Indonesia.

The dissertation, which is now available to the public, is expected to spark new debates and discussions within the academic community about the intersection of geometry, physics, and cosmology.
