Naturally occurring Einstein Rosen Bridges

Physicist Ludwig Flamm came up with a new idea while analyzing some solutions to the equations of general relativity. He proposed another unique solution, which pointed to a new cosmic object called “white hole”.

It was nothing but a hypothetical time reversal of a conventional black hole. Access to both white and black holes could be joined by a space-time tunnel.

Supermassive objects like black holes and neutron stars warp time and space. When such warping goes to another level, the physics of space-time also changes drastically.

In 1935, Albert Einstein and Nathan Rosen extended general relativity to expand the above idea. They proposed the existence of tunnels or bridges through the space-time fabric.

These tunnels could join two distant points in the universe. Thus, creating a weird shortcut that could minimize distance and travel time.

Later, they were named wormholes or Einstein-Rosen bridges.

Wormholes have two openings and a tunnel connecting these entry points. Each spheroidal opening probably contains supermassive objects that could warp space and time. The bridge or tunnel might be twisted or straight, depending on the inherent variables. Most of these are mathematical assumptions.

Theory of general relativity theoretically forecasted the presence of wormholes, but there is still no physical evidence of wormholes. It is interesting to note that some special solutions of general relativity permit the possibility of wormholes with black holes at each end. On the other hand, there is significantly less chance for normal black holes to exist as part of wormholes.

Artificially Created Wormholes (Bridges)

Mathematician Matt Visser stated there could be numerous wormholes if cosmic strings with negative mass were produced early in the universe. Kip Thorne and Frank Tipler put forward the idea of artificial wormholes. The possibility of time travel and teleportation could be vividly explored through these high concept
