SO MUCH FOR A WEEKEND GETAWAY TO PISCIS AUSTRINUS

Experts Say Wormholes, Time Machines Unreliable

According to a new paper by researchers Roman Buniy and Stephen Hsu, traversable wormholes and time machines cannot be both stable and predictable. Albert Einstein and Nathan Rosen published the first scientific paper on wormholes (also called Einstein-Rosen bridges) in 1935, describing how it might be possible for two distant regions of space-time to be connected through a tunnel-like spatial shortcut.
