So far, observations by instruments including the James Webb Space Telescope have revealed the presence of surprisingly massive black holes in the early universe. Even less than a billion years after the Big Bang, some of these bodies already weighed billions of times the mass of the sun, and to date, astronomers are unclear as to how they could have grown so large so quickly.
