James Webb Space Telescope finds supermassive black holes that seem impossibly large

[Admin]

"Little red dot" galaxies discovered by the James Webb Space Telescope in the early cosmos appear to be ruled by supermassive black holes that are 1,000 times too massive.

Wow. Amazingly not surprised.

What is surprising about this article is the age of the LRDs quoted at 1.5 billion years after the BB. Other sources indicate they formed much earlier, with apparent ages of only 600-800 million years*. They seem to 'disappear' around 2 billion years after BB. It is likely they simply acquired more hydrogen/helium to grow into more regular galaxies. M87's SMBH might even have been a LRD very early in its formation and evolution.

In any event, the appearance of these LRDs and other AGNs in the early Universe tend to suggest that galactic core BHs could have formed by different mechanisms, and at least some (if not all) by direct collapse immediately following the BB.
