But supermassive black holes are a conundrum.
Now we know what signature our supermassive black hole generates, astronomers have discovered that the majority of other galaxies also possess supermassive black holes in their cores. Even when looking into the furthest cosmological distances at the youngest known galaxies, they also appear to host these black hole behemoths.
For a black hole to gain so much mass, it's logical to think they need lots of time to pile on the mass - eating interstellar gas, stars and other galactic material. But to explain the earliest supermassive black holes in the youngest galaxies, there had to be some as-yet to be understood rapid growth mechanism.

According to Li and Bambi, however, to explain our observations of Sgr A* and other galaxies' cores, a primordial consequence of Einstein's general theory of relativity may be called into play instead, thereby sidestepping the puzzle of how supermassive black holes grew so big so quickly.
