Quasi Star

A Quasi-star is a type of (extremely) massive star that may have existed early in the universe. The matter in the early universe was so dense that quasi stars could grow to thousands of times the mass of our sun. The cores of these stars might have been crushed by their own weight so much to actually collapse into black holes while the star was still forming. Its energy would come from material falling into a central black hole, as opposed to nuclear fusion. These stars might explain the supermassive black holes that exist today as the universe is simply not old enough for these supermassive black holes to exist.
