Nancy Grace

9 November 2023

Seems like the James Webb Space Telescope is not alone. We now have the Nancy Grace Roman Space Telescope due to come online soon. It could finally tell us if primordial black holes exist, or not. Note – not if black holes exist, just the primordial variety which is an invention of cosmologists. These are to be found close to the Big Bang point. In fact, it seems the idea of Big Bang is at the heart of mainstream thinking in regard to black holes. We are told that when the universe erupted into existence with Big Bang all its matter was compressed into a tiny area. Cosmologists theorise that in some regions sub atomic matter was compressed into an even smaller area – if that is possible. This collapsed into primordial black holes. If they exist they would be small – and hiding. The latter element is important to the story as it accounts for the failure to yet discover them. Einstein’s theory of relativity is said to have provided proof of the existence of black holes. The  elephant in the room here is that Einstein himself disagreed. He didn’t think black holes could actually form. It was other scientists getting onboard the gravy train that played around with Einstein’s equations that claimed black holes could exist. In other words, they took Einstein’s work and came to a conclusion the man himself did not accept. Then, they repeated over and over again, that Einstein had proved their existence. He did not. However, it is true that since then black holes have fascinated scientists – and school boys.

See https://phys.org/news/2023-11-nancy-grace-roman-space-telescope.html ….We are told, with that firm sense of knowledge only the most programmed of our betters, can command, that now we know they do [exist] and we also know they are so dense, they warp space time. We also know even light cannot escape from their clutches. It seems the mainstream mantra of cosmologists is out of sync with other scientists such as solar physicists. The latter are reshaping their ideas on how the cosmos works but in another discipline they are still bedded into the old ideas.

Nancy Grace is a powerful infrared telescope which will be launched in 2027. It is designed to measure dark energy, as one example, as well as the space time curve. Gravitational microlensing is also on the agenda – so black holes, primordial or otherwise, are not the only thing it will illuminate. For more info see https://doi.org/10.48550/arxiv.2311.00751

Keeping to the theme of black holes, at https://phys.org/news/2023-11-supermassive-black-holes-star-formation.html … here we are told supernova black holes shut down star formation. This view is derived from the James Webb once again. Studying cosmic dawn, when the first stars and black holes came into existence, as well as galaxies, the telescope came up with some startling facts not particularly onboard with mainstream dogma. However, at cosmic noon, 2 to 3 billion years after Big Bang, we also have some surprises. This is the point stars and black holes are said to have existed for some time, and qasars. Looking at various galaxies the researchers claim supermassive black holes restrict star formation – see https://doi.org/10.48550/arxiv.2310.17939

Then we have Euclid – Europe’s new space telescope. It is now  beaming back images of the universe at large. See https://phys.org/news/2023-11-glimpses-galactic-zoo-euclid-images.html … which has the first five images beamed back by Euclid. The horsehead nebula is first, then a globular cluster, a dwarf galaxy, and a photo shot of 100,000 galaxies in the cosmic zoo. Awe inspring as some would say.
