Do gravitational waves confirm Hawking's area law?
arXiv:2107.10680
Abstract
Recently an experiment has been performed for the purpose of "testing the area law with GW150914". As the experimenters put it, the experiment presents "observational confirmation" of Hawking's area law based on the GW150914 data. It is the purpose of this paper to philosophically examine the test of the area law and to show that the area law is not confirmable yet is falsifiable. Accordingly, the GW150914 data do not confirm Hawking's area law. What has been tested with positive results was the hypothesis A3 > A1 + A2, where A3 = GW150914 remnant and A1 + A2 = GW150914 merger. But this single instance does not provide observational confirmation of Hawking's area law.
