New evidence for blackhole echoes

For more than year ago I wrote about the evidence for blackhole echoes suggesting that the blackhole created in blackhole collision detected by LIGO is not quite it is expected to be. The echoes suggest a two-layered structure such that the gravitational radiation reflects forth and back between two horizon like surfaces. In TGD framework these surfaces would correspond to ordinary blackhole horizon (more or less) and inner horizon at which the induced metric transforms to a metric with Euclidian signature: this is possible and also unavoidable in TGD Universe. Now Sabine Hossenfelder wrote a blog article about new evidence for blackhole echoes Niayesh Afshordi, Professor of astrophysics at Perimeter Institute. Now the 2.5 sigma evidence has grown into 4.2 sigma evidence. 5 sigma is regarded as a criterion for discovery.

For the TGD based model is described see the chapter Can one apply Occam's razor as a general purpose debunking argument to TGD? of "Physics in Many-sheeted Space-time".
