Question: Why Don’t We Hear the Thing?
(Submitted in response to Soapbox Q&A #2: Is Jack's Air-Braking Mechanism Broken?) If there was a black hole zipping about inside the Earth with apogee near the surface, we’d hear the thing. Doctor Jack's AnswerWhy? It’s not digging a tunnel. It’s not chewing up a whole lot of rock. And its apogee’s probably a good two to ten kilometers down by this time. The Earth is big and no one expects seismic sources to travel at a few KPS. So no one’s looking for such a thing: If anyone were interested in trying, I could suggest several data sources to comb through — from satellite gravity measurements to the UN’s new network for detecting clandestine nuclear tests.
But until somebody does make a deliberate effort, fast transients, like the ones Vurdalak would generate, are
likely to be discarded as “scruff.” Remember Jocelyn Bell-Burnell and the discovery of the first
pulsar. copyright (c) 2005 by amber productions, inc. |
