. In an extreme case, even from a Newtonian standpoint, we can explain why spacetime is accelerating beyond speed of light, if we consider the two sets of masses to be made of purely imaginary complex number valued masses in kilograms and account for repulsive force even from, Newton's law of Universal Gravitation. There can be cases where spacetime could be composed of complex number valued masses in kilogram. This can account for the glue that holds galaxies together. Spacetime could be totally massless vacuum also ie the normal scenario.
Spacetime can be assigned a mass and how to do so is known, there's nothing ``weird'' about it. The Newtonian approximation isn't useful in that case.
The statement that ``spacetime is accelerating beyond the speed of light'' (or any speed for that matter) just doesn't make sense (relative velocity can't be unambiguously defined in curved spacetime). It also doesn't make sense to consider complex values for masses.
It's known what makes sense in classical gravity, so it's not useful wasting time and effort on things that are known not to make sense.
Mr. Nicolis , plz go through my ebook, Amazon pdf, Comprehensive Revision Of Special Theory Of Relativity before making any absolute conclusion.
In special relativity the mass of spacetime-which is flat-is zero. In general relativity it's unambiguously defined for asymptotically flat spacetimes. Nothing weird and no revision is necessary.
You asked the question, here's the answer. If you claim to know the answer, you, usually, don't ask a question, but make a statement.
There are several issues within your thought process. However, I'll give you that issue number 5 is assuming the existence of dark matter is a factual assumption.
1. In general relativity, spacetime itself does not "accelerate" - rather, the curvature and geometry of spacetime can change in response to mass/energy. Spacetime does not have a velocity in GR.
2. Imaginary masses and complex numbers do not have direct physical meaning in terms of real masses or spacetime geometry. While they are useful mathematical constructs, attributing imaginary mass values does not explain empirically observed gravitational effects.
3. Newtonian physics does not have a concept of spacetime curvature - gravity is treated as a force, not a geometric effect. So, trying to explain intrinsic spacetime curvature in Newtonian theory is problematic.
4. Even in Newtonian gravity, there are no repulsive forces between masses - the gravitational force is always attractive between positive masses. Negative or imaginary masses would be needed for repulsion.
5. The "glue" holding galaxies together is generally attributed to dark matter in modern cosmology, not complex spacetime geometry. Dark matter provides the extra attractive gravity.
6. Spacetime is usually treated as a massless entity - the geometry and curvature are influenced by mass/energy, but spacetime itself does not possess mass in most standard physics frameworks.
That being said, I'm open to a counter argument that resolves the above-mentioned conceptual issues. Justifications are always very important when making claims about the nature of things that have already been explained.
I feel like ostentatious stance of Joshua is only bringing a existing counter argument to my novel rationale, when Nicolis has already bungled. I will refute all the 6 points raised in 6 replies below
1. GR theory was never raised and my stance here is why spacetime exceeding the speed of light.
2. Purely imaginary complex number valued masses in kg applied to Newton's Universal Law of Attraction formula yields force which is repulsive also. Plz check my earlier preprint gravitational force can be. repulsive also
3. Infinite amount of repulsive newtonian force, my innovative view mentioned in 2. can account for spacetime exceeding the speed of light.
4. What if spacetime is composed of imaginary masses accounted earlier.Plz read my ebook, Amazon pdf, Comprehensive Revision Of Special Theory Of Relativity.
5. Glue could be a composition of one set of real mass and second set of purely imaginary mass, albeit unable to authenticate.
6. Special theory of relativity has been revised. In less than 1s, for mass variance equation, for purely imaginary masses seem to support , speeds exceeding speed of light, like spacetime and instantaneous quantum communication , which Einstein defended as , " A better understanding of his theory will one day prove him right. Plz read my preprint, Bridging the gap between Einstein and Tesla as far as relativity theory is concerned.
