With more advanced telescopes, astronomers have found fully formed galaxies and colossal black holes earlier and earlier in the cosmos, just a few hundred million years after the Big Bang. This shouldn’t be enough time for these structures to reach their incredible size; to astronomers, it’s like stumbling on a fully-grown oak tree that’s only a year old. The dilemma was put into hyperdrive by the James Webb Space Telescope’s discovery of extremely bright “Little Red Dots” that were present when the universe was less than a billion years old, and are nowhere to be seen today. Though they’re suspected to be some kind of compact galaxy, they would be almost impossibly dense at the mass they appear to have, wall-to-wall with stars, according to Vadim Rusakov, an astronomer at the University of Manchester and lead author of a new study investigating the red objects published in the …
