If you thought the cosmos was a lot to take in, think again. Theorists have long suggested that our universe is just one of many that exist in a complex “multiverse.” Now researchers have found hints that this may actually be the case.

The researchers, who claim to be the first to search observational data for the presence of a multiverse, cannot yet prove that our universe is one of many. However, their analysis, published last Friday on the arXiv preprint server, implies that more-precise data could confirm the existence of a multiverse. “It’s incredibly exciting to think there is even a chance that actual observational evidence for a multiverse might be found in our lifetimes,” says Alan Guth, a cosmologist at the Massachusetts Institute of Technology in Cambridge, who was not involved in the study.
