B Could a Black Hole Power Civilization?

AI Thread Summary
Using a black hole as a power source for civilization is theoretically possible, given the underlying physics. However, practical implementation poses significant challenges, primarily due to the difficulty of transporting civilization to a black hole. Current energy solutions on Earth are more feasible and sustainable compared to harnessing energy from a black hole. The discussion highlights the need for advancements in technology and space travel to make this concept viable. Overall, while intriguing, the idea remains largely impractical with today's capabilities.

TL;DR Summary
Penrose idea to sap angular momentum energy from a black hole via the Ergosphere plausible?
Astronomy news on Phys.org
The physics is fine. But as a practical idea it makes no sense unless you live in orbit around a black hole. Getting our entire civilisation from here to a black hole would be a tiny bit challenging. From where we are, there are far easier ways of getting energy in a sustainable manner.
 

Thread 'Does it make sense to build new radio telescopes?'

TL;DR Summary: In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation. In case of failure to detect alien signals, it will further expand the radius of the so-called silence (or rather, radio silence) of the Universe. Is there any sense in this or is blissful ignorance better? In 3 years, the Square Kilometre Array (SKA) telescope (or rather, a system of telescopes) should be put into operation.

Thread 'Could gamma-ray bursts have an intragalactic origin?'

Thread 'Could gamma-ray bursts have an intragalactic origin?'

This is indirectly evidenced by a map of the distribution of gamma-ray bursts in the night sky, made in the form of an elongated globe. And also the weakening of gamma radiation by the disk and the center of the Milky Way, which leads to anisotropy in the possibilities of observing gamma-ray bursts. My line of reasoning is as follows: 1. Gamma radiation should be absorbed to some extent by dust and other components of the interstellar medium. As a result, with an extragalactic origin, fewer...

Thread 'Could fast radio bursts be alien radar signals?'

Both have short pulses of emission and a wide spectral bandwidth, covering a wide variety of frequencies: "Fast Radio Bursts (FRBs) are detected over a wide range of radio frequencies, including frequencies around 1400 MHz, but have also been detected at lower frequencies, particularly in the 400–800 MHz range. Russian astronomers recently detected a powerful burst at 111 MHz, expanding our understanding of the FRB range. Frequency Ranges: 1400 MHz: Many of the known FRBs have been detected...
