Land bridge theory

By Nola Taylor Redd, Space. Wormholes are predicted by the theory of general relativity. He described a "white hole," a theoretical time reversal of a black hole. Entrances to both black and white holes could be connected by a space-time conduit.

Land bridge theory

InEinstein and physicist Nathan Rosen used the theory of general relativity to elaborate on the idea, proposing the existence of "bridges" through space-time. These bridges connect two different points in space-time, theoretically creating a shortcut that could reduce travel time and distance.

The shortcuts came to be called Land bridge theory bridges, or wormholes. The mouths would most likely be spheroidal. The throat might be a straight stretch, but it could also wind around, taking a longer path than a more conventional route might require. A negative mass wormhole might be spotted by the way its gravity affects light that passes by.

Certain solutions of general relativity allow for the existence of wormholes where the mouth of each is a black hole. However, a naturally occurring black hole, formed by the collapse of a dying star, does not by itself create a wormhole.

Through the wormhole Science fiction is filled with tales of traveling through wormholes. The first problem is size.

Alerts In Effect

Primordial wormholes are predicted to exist on microscopic levels, about 10—33 centimeters. However, as the universe expands, it is possible that some may have been stretched to larger sizes. Another problem comes from stability. The predicted Einstein-Rosen wormholes would be useless for travel because they collapse quickly.

Exotic matter, which should not be confused with dark matter or antimatter, contains negative energy density and a large negative pressure.

Such matter has only been seen in the behavior of certain vacuum states as part of quantum field theory.

EVOLUTION TRENDS:

If a wormhole contained sufficient exotic matter, whether naturally occurring or artificially added, it could theoretically be used as a method of sending information or travelers through space. Unfortunately, human journeys through the space tunnels may be challenging.

Similarly, some scientists have conjectured that if one mouth of a wormhole is moved in a specific manner, it could allow for time travel. Although adding exotic matter to a wormhole might stabilize it to the point that human passengers could travel safely through it, there is still the possibility that the addition of "regular" matter would be sufficient to destabilize the portal.

However, scientists continue to explore the concept as a method of space travel with the hope that technology will eventually be able to utilize them.The Phi shelfmark, which was established in , only stopped being used in when the library opened its Book Storage Facility in Swindon and changed the way it catalogs books.

A wormhole is a theoretical passage through space-time that could create shortcuts for long journeys across the universe.
