According to classic theory, they couldn't be formed in such a short period, but...

They are huge, and it's not possible they exist after "only" 800 million years. But calculations say the existence of super-massive black holes in a primordial Universe is mathematically possible! A recent article, published on The Astrophysical Journal, reports a possible explanation to this head-scratcher.

... it's possibile, by math!

Lumen Boco and its supervisor Andrea Lapi, (Sissa, International Superior School of Advanced Studies) propose a model in which super-massive black holes grows quickly, despite until now they were considered the slowest formation processes, demonstrating that it's mathematically possible according with the age of the Universe, established in about 14 billions years. The theory of the 2 italian scientists will be proved by gravitational waves researchers, like Einstein Telescope or Lisa, but even by actual system Virgo

How is it possible?

Starting on a certain theory: super-massive black holes grows in the center of galaxies, forming the current ecliptic galaxies, rich of gases and in which star formation is very high. Massive stars have a "very short" period of life and their evolution allows the black holes formation. This kind of black holes are thick, just 10-12 solar masses, but they are a lot! Gases around them produce a force that takes them towards to center of galaxy. At this point they melt between themselves, forming a huge black hole that grow more and more.

This is the focal point of this theory

At this moment the mass of the super-massive black hole could reach up to 10.000 or 100.000 solar masses in just 50-100 million years. According to standard theory, the growth will be very fast, and so the existence of this super-massive black holes would be possible, even in a young Universe having less than 1 billion years age
