The current theory about galaxy evolution states that galaxies contain black holes at their core which make up about 0.5% of the galaxy’s total mass.

However, this theory was recently challenged with the discovery of a super massive central galactic black hole, named CID-947, which made up 10% of its galaxy’s mass, stirring up questions about the current theory of galactic evolution, IFL Sciencereports.

The 11.7-billion-year-old black hole seems to have grown faster than its host galaxy. Forming two billion years after the Big Bang, it is among the largest black holes ever found, with a mass of about seven billion times that of the Sun.
