Black Holes Could Be Spacetime Tangles, New Research Shows

Physicists have proposed that stable imperfections in the structure of space-time, known as "topological solitons," could mimic black holes. These solitons could be found all around the universe and could help us understand quantum physics. The researchers found that rays of light passing near these solitons would behave almost the same way as they would around a black hole. However, unlike black holes, topological solitons do not have event horizons, so you could get as close as you wanted and leave if you wanted to. The discovery of topological solitons would be a major insight into the nature of gravity, quantum gravity, and string theory.
