supermassive black holes are formed in the first stage.” itemprop=”image”/> Recent research teams have discovered that the “third family star-type 1” supermassive stars in the early universe may be the predecessor of the supermassive black hole observed today. These stars are the earliest stars formed in the universe. The ultra-high energy photons released quickly ionize the surrounding hydrogen, reaching a distant area of interstellar matter in the universe, and eventually forming an ionization zone spanning millions of light years. The birth of all such black holes is accompanied by a “short ionization” event throughout the universe, ending the “dark period” of the universe.

Supermassive black holes are common in the core of large galaxies, including the Milky Way, and their mass is often millions to billions of times that of the Sun. However, the formation mechanism of these celestial bodies has been controversial, especially as the Weber Space Telescope (JWST), a collaboration between NASA, the European Space Agency and the Canadian Space Agency (CSA), observed a large number of distant black holes born in the early days of the universe.
The “Third Family Star-Type 1” model simulated by the research team believes that these earliest stars were able to grow to extremely huge mass under the action of the energy released by the “dark matter annihilation” in the early universe, and eventually collapsed to form a supermassive black hole. This model has successfully predicted several recent observations from the Weber Telescope. The latest research results further point out that these stars can ionize hydrogen violently in a short period of time and temporarily recreate the universe, and their ionization period is far ahead of the reionization stage dominated by galaxies.
Team scholars pointed out that this period of evolution earlier than the galaxy-led reionization period may provide explanations for many controversial parts that have emerged in cosmology in recent years, including Haber constant tension, dynamic dark energy trace evidence, etc. These questions are challenges to standard cosmological models. This research results provide a two-stage star birth and ionization mechanism: the first stars in the universe may form and disappear quickly in a brief and dazzling way. The extremely early universe observed by Weber Telescope today may be just the “second wave” of star generation. Obviously, in the early stages of the formation of the universe, there may still be surprises hidden.
