Micro black hole facts for kids
Man-made black holes
If the LHC did create a micro black hole, it would disappear immediately, and would not be dangerous. Cosmic rays hitting the Earth's atmosphere may already create these. If dangerous micro black holes are created by cosmic rays, then the Earth would already be damaged. Because the Earth is not damaged by black holes, scientists think they are not dangerous. This thought is like the Anthropic principle.
