Are Tiny Black Holes and Extra Dimensions Hiding in Plain Sight?
November 4, 2026
A report in Physics World summarizes new research by Professor and Chair of Physics and Astronomy Luis Anchordoqui and an international collaborators exploring how tiny, five-dimensional (5D) black holes could have formed shortly after the Big Bang. Building on earlier work suggesting that an extraordinarily energetic neutrino detected in 2023 might have originated from one of these unusual black holes, Anchordoqui and his colleagues have turned to the next question: How could five-dimensional black holes have formed in the first place?
Their new study suggests that if our universe contains a hidden fifth dimension, primordial black holes could have formed naturally, and some might even have survived to the present day. The findings advance Anchordoqui’s ongoing research into high-energy physics, primordial black holes, and the earliest moments of our universe. Additional research on this topic is expected to be published in the coming months, Anchordoqui said.
