The James Webb Space Telescope (JWST) has spotted the oldest black hole ever seen, an ancient monster with the mass of 1.6 million suns lurking 13 billion years in the universe's past.

The James Webb Space Telescope, whose cameras enable it to look back in time to our universe's beginnings, spotted the supermassive black hole at the center of the infant galaxy GN-z11 just 440 million years after the universe began.

And the space-time rupture isn't alone, it's one of countless black holes that gorged themselves to terrifying scales during the cosmic dawn — the period about 100 million years after the Big Bang when the young universe began glowing for a billion years.

These are the massive black holes that lurk at the core of most galaxies. Like the one at the center of our own milkyway galaxy. The question remains do they form at the center of baby galaxies or are they the seed which triggers a galaxy to develop and they just grow even larger over time. If early galaxies had massive black holes for their galaxy size, that suggests the last option. Primordial black holes that is ones that were formed in the big bang have been a possibility for a long time. They have been talked about by astronomers since the 1970s. It great that so much is being discovered now. Lots of surprises still coming I suspect. More info on primeval black holes here. https://physicsworld.com/a/concerning-primordial-black-holes/
