Wormholes, which are strange hypothetical tunnels through space-time, could act as cosmic magnifying glasses for objects behind them
2 February 2023
If wormholes – strange tunnels connecting two regions of space-time – exist, we may be able to spot them by the way they magnify light. This phenomenon, in which light from behind a cosmic object is stretched around the object due to its gravitational field, is called gravitational microlensing, and wormholes may be some of the most powerful lenses around.
Gravitational lensing is fairly common in space and is used to probe some of the biggest mysteries of the universe, including dark matter …
