Warsaw Spacetime Colloquium: Juliusz Doboszewski (22 April on Zoom)

On Friday, 22 April, Juliusz Doboszewski (University of Bonn) will give a talk titled “No ‘No Go’ for LIGO Prediction” (abstract below).

The meeting will be online on Zoom (17:00-19:00 CEST). If you have not registered yet, you can do so here.

ABSTRACT

Some authors have claimed that prediction is “essentially impossible” in general relativity. But what is the scope and importance of the formal results underlying the claim? I will discuss this issue in the context of predictions tested in gravitational-wave astronomy, and show how the experimental setup of the LIGO collaboration avoids the “no go” theorem; this sheds new light on some of the more subtle ways in which physicists use general relativity in making predictions.
