Gmma Rays and Supernovae

At https://www.sciencedaily.com/releases/2024/04/240416125319.htm … a nearby supernova in 2023 failed to produce gamma rays. NASAs Fermi Gamma-ray Space Telescope did not detect any  gamma rays – which appears to contradict mainstream cosmological theory. Trillions of cosmic rays collide with Earth’s atmosphere every day. Some 90 per cent of these are hydrogen nuclei = protons. The rest are electrons = nuclei of heavier elements. It seems these particles cannot yet be traced back to source, and because they are electrically charged, cosmic rays tend to change course as they travel as a result of encountering various magnetic fields in their journeys. Gamma rays, however, are said to travel directly, from A to B. Yet, this particular supernova failed to produce any gamma rays. Astrophysicists insist gamma rays are forged by supernovae.

So, do supernova exist? These explosions occur when a star runs out of fuel, it is claimed, propelling a shock wave outwards. The shock wave accelerates particles, creating cosmic rays. When cosmic rays collide with matter and light surrounding a star they generate gamma rays. Is any of this a problem?

At https://www.sciencedaily.com/releases/2024/04/240416115955.htm … a massive black hole has been found in our galaxy, it is claimed. It was spotted in data beamed back by the ESA Gaia Mission as it imposes an odd wobbling motion as the companion star orbits it. It does of course require a binary system – one of which has become a black hole. Such black holes, we are told, are formed by the collapse of massive stars. It is just 2000 light years away from Earth. Is this another mystery?

The same story is at https://www.space.com/milky-way-biggest-stellar-mass-black-hole-gaia … intense tidal forces in surrounding matter, causing it to glow brightly as a result of material being consumed – but also emitting X-rays. Black holes do not emit or reflect light, meaning they can only be seen when they are surrounded by material that they gradually feed on. Sometimes, this means a black hole in a binary system pulling material from a companion star, which forms a disk of gas and dust around it. The gravitational influence of black holes generates intense tidal forces in surrounding matter, causing it to glow brightly with material the black hole does not feed upon. This is channelled to the poles and blasted out at near light speed jets – which are seen as an emission of light. Hence, the mysterious jets associated with black holes. All these light emissions can allow astronomers to spot black holes – but what about dormant black holes. The ones that are not feeding. In a binary system, the companion star, or one orbiting too far away to be swallowed, means the astronomer  looks for a wobbling motion. Both companion star and black hole are assumed to be circling a point that represents the system’s centre of mass. The black hole is thought to induce the wobble. Hence, what has been discovered is not necessarily a black hole but a star with a wobbling orbit. Theory interprets observations.
