I am working on a research project where I intend to describe what the Penrose process would like in a sonic black hole. I have found what a rotating (Kerr) black hole looks like in the sonic analog: https://arxiv.org/pdf/1802.08306.pdf I have also found that the analog of massless particles...

Also, you mentioned that in the Penrose process it is difficult to transfer energy across interstellar distances. I know that there is current technology being developed to beam energy from space down through Earth’s atmosphere using lasers. Could the energy from the Penrose process be carried...

Thank you for your replies. I am new to this, but could there be any application from the recent detections of gravitational waves at LIGO to harnessing energy? For example, could gravitational waves from black holes be used as an energy source? If you know of any related scientific papers, I...

Whether it be through Hawking radiation, miniature black holes, or even white holes, is it possible that one day energy could be harnessed from black holes and used on earth?

I am reading Carroll’s Spacetime and Geometry, and I have seen the word “coupled” used multiple times in seemingly different ways. I have gotten the sense that it means some sort of interaction between particles, but Carroll refers to coupling between matter fields and the curvature of...
