I'm sure that the topic of Schwarzschild wormholes or Einstein-Rosen bridges have been debated in the past but I would like to get a fresh
perspective on where everyone stands concerning the topic.
In physics, a wormhole is a hypothetical topological feature of spacetime that is essentially a 'shortcut' through space and time. A wormhole has at
least two mouths which are connected to a single throat. If the wormhole is traversable, matter can 'travel' from one mouth to the other by passing
through the throat. While there is no observational evidence for wormholes, spacetimes containing wormholes are known to be valid solutions in general
The term wormhole was coined by the American theoretical physicist John Wheeler in 1957. However, according to Coleman and Korte, p.199 of 'Hermann
Weyl's Raum - Zeit - Materie and a General Introduction to His Scientific Work', Hermann Weyl invented the idea of wormholes in 1921 in connection
with his analysis of mass in terms of electromagnetic field energy.
This analysis forces one to consider situations..where there is a net flux of lines of force through what topologists would call a handle of the
multiply-connected space and what physicists might perhaps be excused for more vividly terming a ‘wormhole’
– John Wheeler in Annals of Physics
Traversable wormholes would allow travel from one part of the universe to another part of that same universe very quickly or would allow travel from
one universe to another. Wormholes connect two points in spacetime, which means that they would allow travel in time as well as in space. The
possibility of traversable wormholes in general relativity was first demonstrated by Kip Thorne and his graduate student Mike Morris in a 1988 paper;
for this reason, the type of traversable wormhole they proposed, held open by a spherical shell of exotic matter, is referred to as a Morris-Thorne
wormhole. Later, other types of traversable wormholes were discovered as allowable solutions to the equations of general relativity, such as a type
held open by cosmic strings which was put forward in a 1989 paper by Matt Visser.
"By journeying through a wormhole, you could travel between the two regions faster than a beam of light would be able to if it moved through normal
I'm especially interested in the concept of using such wormholes for space travel and exploration. I understand that the Idea is still in it's
infancy and that most scientists would label it as impossible due to the theory that the size of the opening in the wormhole, as we understand it, is
too small to allow the entry of spcaecraft or even humans and it's not staible enough to even allow one photon of light to pass through it before it
In 1988 Michael Morris and Kip Thorne may have come up with a theory on how to stabalize a wormhole. They theorize that a region of negative-mass
energy was needed in the wormholes "throat". This negative energy can be created by using the Casimir effect, which is basically a quantum effect
in which long-wave length vacuum fluctuations are suppressed in a region between conducting surfaces. The problem that lies with this theory is that
the consensus among physicists is that the use of negative energy to contruct a wormhole with normal matter is impossible.
I'd be interested in the views and opions from anyone concerning this debate on wormhole physics and if space/time travel could be accomplished.
