@ paddoboy:

Unphysical speculations are not "predictions", they are mathematical 'solutions'

Nonsense! Unphysical observations such as time, space, spacetime, curvature/warping of spacetime, are just real.

If you consider the EMF as real than so too is spacetime.

**What is a space time continuum?**
In 1906, soon after Albert Einstein announced his special theory of relativity, his former college teacher in mathematics, Hermann Minkowski, developed a new scheme for thinking about space and time that emphasized its geometric qualities. In his famous quotation delivered at a public lecture on relativity, he announced that,

*"The views of space and time which I wish to lay before you have sprung from the soil of experimental physics, and therein lies their strength. They are radical. henceforth, space by itself, and time by itself, are doomed to fade away into mere shadows, and only a kind of union of the two will preserve an independent reality."*
This new reality was that space and time, as physical constructs, have to be combined into a new mathematical/physical entity called 'space-time', because the equations of relativity show that both the space and time coordinates of any event must get mixed together by the mathematics, in order to accurately describe what we see. Because space consists of 3 dimensions, and time is 1-dimensional, space-time must, therefore, be a 4-dimensional object. It is believed to be a 'continuum' because so far as we know, there are no missing points in space or instants in time, and both can be subdivided without any apparent limit in size or duration. So, physicists now routinely consider our world to be embedded in this 4-dimensional Space-Time continuum, and all events, places, moments in history, actions and so on are described in terms of their location in Space-Time.

Space-time does not evolve, it simply exists. When we examine a particular object from the stand point of its space-time representation, every particle is located along its world-line. This is a spaghetti-like line that stretches from the past to the future showing the spatial location of the particle at every instant in time. This world-line exists as a complete object which may be sliced here and there so that you can see where the particle is located in space at a particular instant. Once you determine the complete world line of a particle from the forces acting upon it, you have 'solved' for its complete history. This world-line does not change with time, but simply exists as a timeless object. Similarly, in general relativity, when you solve equations for the shape of space-time, this shape does not change in time, but exists as a complete timeless object. You can slice it here and there to examine what the geometry of space looks like at a particular instant. Examining consecutive slices in time will let you see whether, for example, the universe is expanding or not.

And you seem to be the only one interested in physicists personal categorical in/out opinions. The rest of us look to the real science itself, not the publish or perish and sci-fi fodder you enjoy so much while missing the real science altogether.

The personal categorical opinions you talk about are what mainstream is generally accepting, and that most certainly trumps the unsupported, unqualified, and religiously inspired preachings of some on this forum.

Are you so blind to that fact.

The publish or perish nonsense you mention, is also a fallacy, and a fabricated fallacy pushed by Maverick scientists, cranks, trolls, and those with agendas.

Great! Then there is no argument on the science which says they are unphysical fantasy/maths spculations upon speculations.

Unphysical does not mean "not real"as I have taken the trouble to explain many times... speculative scenarios in the OP and paper, has never been disputed by me, but most certainly confused by yourself, probably due to amount of pretentious nonsense that fills your posts.

But speculative scenarios, as per those in the OP and paper, will continue to be researched by the professionals, and until they have an answer with some certainty one way or the other.

**No Physicist has ever said that worm holes categorically do not exist.**
When you finally twig to that simple fact, you will have twigged to the nature of the OP and paper by the noted renowned physicists Professor Susskind.
