Hypothesis in Contemporary Astrophysics—Could Galactic Interactions Occur Sooner? Relativistic Temporal Effects in Milky Way–Andromeda Encounters

Throughout the second part of the Modern Era, leading researchers in astronomy, physics and applied statistics into astrophysics have brought a novel hypothesis, in which it was speculated that the Milky Way will experience a clash with another galaxy as a result of an intersection in their motion. Currently, such a statement is purely speculative in nature, although specific signs that such a hypothesis reflects real-world phenomena have started appearing, which cover seemingly increased frequencies and extents of planetary and stellar alignments within the Milky Way. Any occurrence of such a phenomenon may be probable due to increased electromagnetic and gravitational influences from outside the galaxy, which may hint at an existing approach of a different galaxy towards the Milky Way. It may be important to mention that potential effects of a multi-galactic crash would involve a general polarisation of natural and spatial phenomena, given that a multi-galactic interaction and clash would involve a sharp, unprecedented increase in the extent of electromagnetic and gravitational fluctuations of influences toward the Earth, which would affect all natural phenomena upon it, including the climate, the weather, human and animal psychology and wellbeing, as well as the effects of seas and oceans upon nearby shores. Furthermore, if the hypothesis in which major electromagnetic and gravitational influences toward specific, earthquake-prone geographical areas of the Earth would increase the probability of the occurrence of novel earthquakes and aftershocks in such areas is proven to be evidence-based, then a multi-galactic clash involving the Milky Way could also result in a sharp increase in both the frequency and extent of earthquakes throughout the Earth. Furthermore, it could be that the increasing number of people “bumping” into numerical and geometrical coincidences of symmetry at random (i.e. an increasing number of people bumping into “angel numbers”) is a sign of existing increases in electromagnetic and gravitational influences from the cosmos, which may very well reflect a scenario of an approaching multi-galactic interaction that may in a lower probability scenario even implicate the Milky Way (i.e. perhaps with Andromeda in approximately 4.5 billion years). According to Albert Einstein’s Theory of Relativity, time is not an absolute entity, but a relative measure that can be contracted or dilated depending on the observer’s perspective. Nonetheless, such relativistic effects are technically imperceptible on Earth, just as passengers aboard a high-speed train experience stability and consistency within the train, regardless of its external speed. Similarly, the inhabitants of the Milky Way could remain unaware of significant relativistic changes in galactic motion, whilst natural and cosmic phenomena within the galaxy would paradoxically accelerate in a manner reflective to the acceleration of time, thereby “transforming” the 4.5 billion years potentially into a much shorter time frame. If the Multiverse is real, then the same analogy applies for the inhabitants of the Universe. Furthermore, it may be important to observe whether any double-exponential growth in the speed of the approaching galaxies has been taken into consideration, which would broadly shorten the duration of 4.5 billion years and also change the relativistic states of time within the implicated galaxies - whilst keeping the internal measurements of time intact. Any real-world application of such an analogy may bring implications that deeply intersect scientific and philosophical research, perhaps even offering a hypothesis in which traditional cosmological models that suggest an 11-billion year process of evolution of physical matter, may not be mutually exclusive with theological narratives, such as a “Seven-Day Creation”. Some hypotheses have even proposed a paradoxical existence of a relative state of the speed of light, although empirical scientific evidence states that it is an absolute value, which constitutes the foundation of Albert Einstein’s research.Such hypotheses could nonetheless operate according to the Philosophical model of “destroy the Temple and rebuild It afterward”, potentially resulting in the creation of the most foundational type of a paradox in which the speed of light would be deemed as both relative and absolute, which could constitute “the paradox of all paradoxes”. Effects of any multi-galactic interaction implicating the Milky Way may accelerate the production of more stars and planetary systems, and preserve existing forms of life, given that a clash between Sagittarius Dwarf and the Milky Way may have resulted in the creation of the Solar System. Or, such an interaction deemed to probably occur, and in the distant future, could describe religious passages in which a phenomenon of “star falling” is mentioned, which could also involve an increasing number of asteroids falling upon Earth, given that fluctuations in gravitational influences could cause asteroids from the great belt nearby Jupiter to change their direction, leading to increased statistical probabilities that more asteroids will change their direction and be headed toward the Earth. Such a phenomenon could be deemed as “beyond monumental” in nature and even impact the state of time within the interacting galaxies, given its relative nature - potentially accelerating it considerably as the galaxies approach one another, in proportion with the level of fluctuations in electromagnetic influences toward the Solar System. Overall, the effects of a multi-galactic clash could either create more life or be catastrophic for human and animal life, potentially resulting in a phenomenon of unprecedented population loss in all life forms. Likewise, it may be important for research efforts to continue in order to determine whether the Milky Way is indeed in the course of experiencing an unprecedented intersection with a different galaxy, as well as for scientists, local and international authorities to devise plans of preparation for the purpose of precaution and ensuring that all guidelines of Health & Safety are met in case of any increased frequency and extent of natural disasters throughout the Earth, whilst keeping academic and scientific perspectives in an optimistic realm, based on the available evidence. This preprint also develops a speculative but explicitly testable applied mathematics-related hypothesis concerning large-scale galactic interactions and their possible influence on coarse-grained temporal observables for extended gravitational systems. While General Relativity uniquely defines proper time along individual worldlines, it does not uniquely prescribe how clock rates should be aggregated across spatially extended, self-gravitating domains such as galaxies when these systems are embedded in non-uniform external gravitational fields. Building on this conceptual gap, we introduce a phenomenological “structural time” for a bound system G, defined through a coarse-grained lapse factor χG​, and propose a minimal extension in which χG​ acquires a weak dependence on external tidal curvature invariants. The model is constructed covariantly using the electric part of the Weyl tensor and a dimensionless tidal-strength parameter ΛG ≡ TG / (ΩG2), where TG = sqrt (Eab * Eab) measures the external tidal field and ΩG​ is a characteristic internal dynamical frequency. The modified lapse takes the form χG = χG,GR * [1 + ε * ΛGp]−1/2, recovering the standard GR coarse-grained result when ε=0. Applied to the Milky Way – Andromeda system, the present-day tidal strength is strongly suppressed (ΛG ∼ 10−5 for fiducial parameters), implying that any effect on coarse-grained timekeeping is expected to be extremely small at current separations unless the coupling ε is unexpectedly large. A distinctive observational consequence is a fixed-axis quadrupolar anisotropy in timing or frequency measurements aligned with the dominant external mass distribution, providing a falsifiable template for pulsar timing arrays and high-precision optical-clock networks. The broader conceptual motivation of the paper is to explore whether system-level temporal observables, when defined through coarse-graining, could carry weak environmental dependence in galactic settings without modifying local tests of General Relativity. More broadly, the framework suggests that certain aspects of relativistic time may require refined interpretation when applied to spatially extended, self-gravitating systems rather than idealised point observers. In this sense, the present work does not modify the field equations of General Relativity, but instead proposes an operational extension in how relativistic time may be defined after coarse-graining across large astrophysical domains subject to external tidal curvature. Such a perspective may help in thoroughly expanding the application of relativistic concepts to galactic-scale dynamics while remaining fully consistent with the extensive body of experimental tests confirming General Relativity in local and weak-field regimes.
