Detection of a Primordial Black Hole
Primordial black holes, if they exist, would be challenging to detect and would provide insights into the early universe. Scientists have never truly figured out what happens after entering a hole since nothing has ever come out. The existence of a primordial black hole is completely hypothetical.
They were proposed by some scientists to explain the unexpected very large early galaxies originally discovered by the James Webb Space Telescope (JWST). At the very least, scientists hope these will help them discover more about dark matter. According to The Conversation, “Primordial black holes might be located in galactic regions where the concentration of dark matter is remarkably high. Thus, they could roam the Universe (moving at different speeds and directions) and eventually interact with other astronomical objects (such as black holes or neutron stars).” There’s no saying if this discovery will ever be made during our human existence (The Conversation).
