Spot a Wormhole
the post: How to spot a wormhole (if they exist)
my comment:
Some day this wormhole fantasy must go away. The uses of a wormhole are multiplying and getting more ridiculous. Spacetime is not a magical 4D contour map of the universe where the observer picks the 3D coordinates in space and also a time coordinate and so the observer can move to that 4D coordinate combination. Time is not a dimension one can move along, by picking a coordinate. Time is an incrementing count used for monitoring motion and for monitoring changes in molecular bonds, which are not instantaneous, in chemistry.
Thermo dynamics describes the conservation of energy; these energy transfers (and everything involved with them) are not reversible by changing a time coordinate. Collisions convert kinetic energy into thermal energy; these energy transfers and the conditions of the collision are not reversible.
This silly study is pure fantasy. It is not even 'theoretical.'
In relativity, a black hole is maximum spacetime curvature down to a geometric point in the 4D coordinate system being distorted. A point in geometry has no physical size, neither do lines or planes. Nothing in a coordinate system is real; it is used for describing positions. To excuse the misuse of geometry concepts in physics this geometric point is called a singularity so this 'thing' can have mass in it with infinite density. Because a point has no physical size the black hole, disregarding physics, suggests the mass causing this 4D coordinate system disruption is also collapsed into this geometric point. A nonphysical geometric point has an infinite capacity and so an infinite amount of mass can be proposed as being in this nonphysical geometric point.
This study proposes the force of gravity passes into a black hole singularity, which is considered a possible wormhole in spacetime, and in some physically impossible manner affects another mass located at some other 4D coordinate in this magical spacetime's 4D map of the universe.
The author of this study is a professor of physics but this study is a work of pure fiction. Hit back to go to previous page in history.
