Oral

The first-order thermodynamics of scalar-tensor gravity is an analogy between scalar-tensor gravity (including viable Horndeski) and dissipative fluids. Assuming the gradient of the gravitational scalar field to be timelike and future-oriented, it contributes to the field equations like a dissipative fluid which, surprisingly, obeys Eckart's version of the Fourier law. Then, the convergence of...

17. GR and EDI

Oral

Is GR open to EDI concepts? Are relativists considering inclusivity in their research and teaching? In this talk, I will try to draw a picture of GR with an EDI perspective and show my students' perspective as first-time relativity learners.

8. Gravitational Field of an Oscillator in Proper Time

Hou Yau

Oral

We show that a proper time oscillator can mimic a point mass at rest in general relativity. The spacetime outside a proper time oscillator is a Schwarzschild field. Although the singularity in our model acts as a boundary for incoming geodesics, the spacetime structure inside this boundary is well-defined. The proper time oscillator is cloistered behind the singularity.
