The Natario warp drive appeared for the first time in 2001. Although the idea of the warp dive as a spacetime distortion that allows a spaceship to travel faster than light predated the Natario work by 7 years Natario introduced in 2001 the new concept of a propulsion vector to define or to generate a warp drive spacetime. Natario defined a warp drive vector for constant speeds in Polar Coordinates but remember that a real warp drive must accelerate or de-accelerate in order to be accepted as a physical valid model so it must possesses variable speeds.We developed the extension for the original Natariowarp drive vector that encompasses variable speeds.Also Polar Coordinates uses only two dimensions and we know that a real spaceship is a 3D object inserted inside a 3D warp bubble that must be defined in real 3D Spherical Coordinates.In this work we present the new warp drive vector in 3D Spherical Coordinates for both constant or variable speeds.

Starting from first principles, we point out an apparent contradiction in the behavior of light in the metric space of a stationary frame in gravity. We show that the issue is resolved provided an independent moving ’dual space’ exists along side the metric space of general relativity (GR). In this dual space clocks run at equal rates to first order but coincide with the time dilation of metric space, due rather to different light path lengths. We find its mathematical properties coincide with the Gullstrand—Painleve coordinates, however the interpretation dictated by this model requiressome different concepts to that of the standard river model. Objects fall at equal rate in this space not because of equality of gravitational and inertial mass but because they are stationary in the dual space which itself is falling. The space behaves more Galilean than one might expect. We explore how escape velocity is modelled in this moving spacetime and address how the dual space re-interprets gravitational redshift to unify it with doppler and Hubble and as well as perhaps dark energy. natural aplications for mass variation and radiating charges stationery in gravity are also presented as a logical result of adopting the framework. We then touch on how the dual space can be modelled as a vector field in geometric algebra.

The theory of special relativity is developed with two stipulations that any propagating electromagnetic wave travels at the same constant speed c, with respect to all inertial reference frames irrespective of their relative velocities and any IRF shall synchronize its spatially separated clocks by the assumption or convention that the one way speed of light within that IRF is constant and equal to c in all directions. The mathematical development of these concepts lead us to the principle of the relativity of simultaneity, the space-time continuum and the block universe that implies the existence of past, present, and future in a four-dimensional space-time continuum. The principle of relativity of simultaneity essentially means that the tenses, past, present, and future, are an illusion. Time order of events are subjective and thus all events in the universe exist together on the continuum. We show that the characteristics of light propagation are the same whether we use the Lorentz Transformation (LT) or the Galilean Transformation (GT) in the sense that the amplitude of the propagating wave at any space-time location remains the same in both the transformations. We argue that the space and time coordinates assigned to any space-time point are different in LT and GT but the identity of a space-time point is not compromised. The different numbers of space and time coordinates assigned to a space-time point by LT and GT arise out of calibration differences and do not indicate any altered reality.

[This paper] investigate[s] the mathematical and physical applications of relative non-locality in general relativity and using it to bridge the gap between general relativity and quantum mechanics without the need for a new unifying theory, in fact both theories are compatible when we put the relative non-locality in perspective, it's first introduced by Einstein in 1911, the relative non-locality is the illusion of superluminal speed phenomena due to the difference in spacetime gravity potential between two points in space, this illusion of superluminal speed is a direct indicator of spacetime curvature difference between two intervals in space such that the conditions of curvature difference is the key element to solve the compatibility problem between general relativity and quantum mechanics, then by following this line of work I found that Einstein field equation is compatible with uncertainty principle in a way that the stress energy tensor could be extract from the momentum uncertainty in the uncertainty principle, this happened only when we have a quantum entangled system of collective masses of bigger than or equal to half Planck-mass as minimum requirements to bend spacetime, then by using quantum entangled system with a rest mass of half Planck mass or more and then by using this knowledge I put the requirements for an experiment to generate artificial gravitational singularities in particle accelerators as a good way to test this paper and its very promising way for both nuclear fusion and superluminal space travel.

The Michelson-Morley experiment and its resolution by the special theory of relativity form a foundational truth in modern physics. In this paper we examine and generalise the geometry of the sequence of events within a standard MM interferometer to arrive at a geometry that merges the perspectives of the rest and moving frames within a common stationary circle in space. Further we show that this theoretical approach leads us into spherical trigonometry that supplies a simple solution of the Michelson-Morley problem that is compatible with Einstein’s paradigm.

In this study, we extend previously established results of relativized Newtonian dynamics—originally derived for inertial rectilinear motion—to the context of a uniformly rotating disk. Our findings reveal the presence of a nonluminous component coexisting with the luminous component, with the ratio of their radial densities being solely dependent on the rotation velocity.We apply these results to investigate the dynamics of both luminous and nonluminous matter in a diverse sample of 52 galaxies from the Spitzer Photometry & Accurate Rotation Curves (SPARC) dataset. For each galaxy, we calculate the radial density distributions of both matter components using only the measured rotation curves. The predicted radial density profiles of the nonluminous components closely trace the observed rotation curves for all tested galaxies.Our analysis indicates that the nonluminous component begins to dominate over the luminous component at rotation velocity of approximately V_flat/3. At rotation velocities approaching V_flat, the luminous component nearly vanishes, with the majority of the matter being nonluminous. The nonluminous component is expected to strongly dominate in all tested galaxies, with a fraction (0.757 ≤ f_NLM ≤ 0.990, σ_(f_NLM )= 0.0137).Moreover, consistent with the Radial Acceleration Relation (RAR), the correlations between the estimated total masses of the luminous and nonluminous components, and between the luminous component and the total dynamical mass, are very strong (r = 0.947 and 0.954, respectively). Additionally, in agreement with the Baryonic Tully-Fisher Relation (BTFR), the correlation between the total luminous mass and V_flat is also substantial (r = 0.626).These results suggest that key features typically attributed to exotic dark matter particles in galactic halos can be accounted for by simple relativistic considerations.
