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.

You can address any inquiry to antonio.vassallo@pw.edu.pl.


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.
