Scientists speculate colossal black holes, much larger than supermassive ones
The study showed that incredibly large black holes can exist in the Universe, the sizes of which are much larger than supermassive ones.
It is believed that supermassive black holes form in their host galaxies and reach enormous sizes, swallowing up the surrounding stars and gas or merging with other BHs. Therefore, in previous studies, scientists assumed that their maximum mass could only slightly exceed 10 billion solar masses.

However, in their recent work, astrophysicists from Queen Mary University of London talk about the possibility of the existence of “colossal black holes.” They are considering an alternative way of formation of primary BHs that appeared in the early Universe, long before the first galaxies.
Scientists believe that since at that time black holes were formed as a result of the collapse of entire regions of space due to their increased density, they can be incredibly huge in size, significantly exceeding the possible limit of supermassive ones.
While such objects alone will not help scientists solve the dark matter puzzle, their combination with smaller primary BHs can do just that.
