Blackholes that grow quite too fast

Marko Manninen ask for the TGD view concerning the recently found black-hole like object (BH) which seems to gobble the matter from environment much faster than it should (see the popular article ‘Fastest-feeding’ black hole of the early universe found. But does it break the laws of physics?. This BH found by the James Webb telescope should have gotten its mass of more than 7 million solar masses in 12 million years. The rate for its formation would have been 60 times too high.

BHs thought to be black holes often differ in many respects from the black holes of general relativity. In particular, the giant BHs of the very early universe and BHs associated with quasars and the cores of galaxies do so. Star-born BHs could be ordinary blackholes but the giant BHs might be something different. The basic mystery is why these BHs can be so large in the very early Universe if they are formed in the expected way. Do the BHs always grow by gobbling up matter from the environment?

TGD leads to a view of BHs different from the GR view in many respects (see for instance this).

1. In TGD, BHs are not singularities containing their mass at a single point but would correspond to portions of long cosmic strings (extremely thin string-like 3-surfaces), which have formed a tangle and thickened so that they fill the entire volume. BH property would mean that they are maximally dense.
2. The thickening liberates the energy of the cosmic string and BHs would transform in an explosive way into ordinary matter, which is feeded into the environment. The accretion disk would not be associated with the inflowing matter, but would be formed by the outflowing matter as it slows down in the gravitational field and forms a kind of traffic jam. Radiation would escape. The situation would be very similar to the standard picture where the outgoing radiation would be produced by the infalling matter. At the QFT limit of TGD, the metric in the exterior region would be in a good approximation Schwartschild metric.
3. BH would be more like a white hole-like object (WH). Zero-energy ontology indeed predicts BHs as the time reversals of WHs. Matter would really fall into them. One can make quite precise predictions about the mass spectrum of these objects (see for instance this).

This vision leads to a model for the formation of galaxies and generation of ordinary matter from the dark energy assignable to the cosmic strings, which would dominate in the very early Universe (see for instance this).

1. The collisions of the cosmic strings are topologically unavoidable and would lead to their thickening and heating inducing the formation of WHs and their explosive decay to ordinary matter. This would generate a radiation dominated phase, perhaps when the temperature approaches the Hagedorn temperature as a maximal temperature for string-like objects. These WHs would be the TGD equivalent for the vacuum energy of inflaton fields assumed to decay to ordinary matter.
2. The energy of cosmic strings would have Kähler magnetic and volume parts and have interpretation as dark energy. There is now rather convincing evidence for connecting between dark energy and the giant blackholes.
3. An unexpected connection is that galactic dark matter would be dark energy of a cosmic string transversal to the galactic plane and containing galaxies along it: this has been known for decades! There would be no dark matter halo and no exotic dark matter particles. This predicts without further assumptions the flat velocity spectrum of the distant stars rotating galaxies associated with very long cosmic strings and also solves the many problems of the halo models and MOND.
4. TGD also predicts dark matter-like macroscopically quantum coherent phases of ordinary matter for which the effective Planck constant h_eff is large. The generation of these phases at magnetic bodies, for example in biology, solves the problem of missing baryonic matter: that is why baryonic (and also leptonic) matter disappears during the cosmic evolution.

Let’s return to the question whether TGD can explain why the blackhole-like objects in question grow so fast. They do not do so by gobbling the matter from the environment but from the long cosmic string. The energy of the thickening string filament is converted into matter and generates a WH. This could happen much faster than the growth of a black hole in the usual way. At this moment it is not possible to estimate the rate of this process but it could explain how the early Universe can contain these giant blackhole-like objects.
