Wormholes are one of the stranger objects that arise in general relativity. Although no experimental evidence for wormholes exists, scientists predict that they would appear to serve as shortcuts between one point of spacetime and another. Scientists usually imagine wormholes connecting regions of empty space, but now a new study suggests that wormholes might exist between distant stars. Instead of being empty tunnels, these wormholes would contain a perfect fluid that flows back and forth between the two stars, possibly giving them a detectable signature.
The scientists, Vladimir Dzhunushaliev at the Eurasian National University in Kazakhstan and coauthors, have posted their investigation of the possibility of wormholes between stars on arXiv.org.
The scientists began investigating the idea of wormholes between stars when they were researching what kinds of astrophysical objects could serve as entrances to wormholes. According to previous models, some of these objects could look similar to stars.
