(With apologies for cross-posting)

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

at the Faculty of Administration and Social Sciences, Warsaw University of
Technology. The program for this semester is 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.
