At https://phys.org/news/2023-11-astronomers-supernova-remnants-meerkat.html … the MeerKAT radio telescope has been used to look at a region of the sky where a supernova was observed breaking up. Supernova remnants have been useful for a variety of prospective theories. In this instance, the study, found on the arXiv preprint server, has something different to say. They are thought to increase the accleration of galactic cosmic rays, as an example.
While at https://phys.org/news/2023-11-gravitational-binary-black-hole-merger.html … we are told that in using gravitational wave observations to explore binary black hole mergers, they can verify ‘no hair’ theorem. Are they using a theory to support another theory, on top of even another theory?
At https://www.livescience.com/space/astronomy/james-webb-telescope-reveals-nursery-of-500000-stars-in-the-chaotic-heart-of-the-milky-way … here we are back to the heart of the Milky Way and a region close to the hypothetical black hole. Thousands of new born stars have been discovered, it is thought.
