US EditionFirst ever 'black hole bomb' created in the lab
- Physicists led by Marion Cromb created the first laboratory analogue of a black hole bomb in 2025 at the University of Southampton.
- This experiment tested the Zel’dovich effect, proposed in the 1970s to extract rotational energy using a rotating absorbing cylinder and a reflective boundary.
- The setup used a rotating aluminum cylinder surrounded by magnetic coils generating a rotating electromagnetic field leading to self-amplifying electromagnetic modes seeded by background noise.
- Researchers observed an exponential then super-exponential growth of electromagnetic energy driven solely by the cylinder’s mechanical rotation, confirming the ‘black hole bomb’ amplification mechanism.
- The findings validate theoretical physics concepts, highlight potential instability risks in rotating electromagnetic systems, and suggest further research on managing such instabilities for future technologies.

Scientists Build First-Ever 'Black Hole Bomb' Analog
Researchers have created the first laboratory analog of the 'black hole bomb', a theoretical concept developed by physicists in the 1970s.If there's one thing black holes are known for, it's their insatiable, inescapable gravity. Stuff goes into a black hole. You're not really going to get much out. From beyond the event horizon, this is, as far as we know, true. But from the space around a black hole, you might be able to get something. As …
