What is the News?
A team of physicists has created the first-ever wormhole, a tunnel that connects two distant points in space and time. This wormhole is like the magical Bifrost bridge in Marvel Cinematic Universe movies.
What is Bifrost?
The Bifrost is nothing but an Einstein-Rosen bridge or a wormhole — theorized in 1935 by Albert Einstein and Nathan Rosen.
What is Wormhole or Einstein-Rosen bridge Theory?
A wormhole is like a tunnel between two distant points in our universe that cuts the travel time from one point to the other. Instead of travelling for many millions of years from one galaxy to another, under the right conditions, one could theoretically use a wormhole to cut the travel time down to hours or minutes.
Because wormholes represent shortcuts through space-time, they could even act like time machines. A person might emerge from one end of a wormhole at a time earlier than when s/he entered its other end.
Is Wormhole theory fact or fiction?
Because of interesting features, many science fiction writers use wormholes in novels and movies. But the presence of wormholes has not yet been established through observation or inference by astronomers.
However, scientists often see wormholes described in the solutions to important physics equations such as Einstein’s theory of space-time and general relativity.
