In the scientific worldview of this timeline, the phenomenon of gravity is not understood as a fundamental force of nature, but rather as an emergent property arising from the underlying structure and curvature of space and time. This alternative perspective on gravity was pioneered in the 19th century by the influential German philosopher and mathematician Johann Gottlieb Fichte, whose metaphysical theory of space-time had a profound impact on subsequent scientific thought.
Fichte, building on the idealist tradition of Immanuel Kant, posited that space and time were not absolute, Newtonian constructs, but rather relative, subjective frameworks shaped by the mind. He argued that the apparent "force" of gravity was not a fundamental interaction between masses, but rather a consequence of the curvature and distortion of this subjective space-time manifold.
In Fichte's view, massive objects such as planets and stars did not "attract" each other through a mysterious force, but rather their presence "warped" the underlying fabric of space-time, causing other objects to appear to "fall" toward them. This space-time curvature model provided an elegant philosophical explanation for many gravitational phenomena observed in nature, from the orbits of celestial bodies to the trajectory of falling objects.
Fichte's ideas gained significant empirical support over the course of the 19th and early 20th centuries. Experiments and observations, such as the bending of starlight around the Sun and the precession of Mercury's orbit, seemed to confirm that gravity was indeed an effect of space-time curvature rather than a fundamental force. This lent credence to Fichte's metaphysical framework and made it a dominant paradigm in scientific thought for many decades.
However, Fichte's space-time curvature theory of gravity, while philosophically appealing and observationally supported, ultimately fell short of providing a comprehensive physical explanation comparable to Albert Einstein's general relativity. Without the advanced mathematical apparatus of tensor calculus and non-Euclidean geometry developed by later physicists, Fichte's model lacked the predictive power and explanatory depth to fully account for all gravitational phenomena.
In particular, the Fichtean framework struggled to explain the existence of black holes, the dynamics of the Big Bang, and the propagation of gravitational waves - all of which are central to our modern understanding of the universe. This left significant gaps and blindspots in the scientific worldview of this alternate timeline, with major implications for the fields of astronomy, cosmology, and space exploration.
The prevailing Fichtean view of gravity, while influential, never achieved the same level of unification and predictive power as Einstein's general relativity in our own timeline. As a result, fundamental physics in this alternate world remains more fragmented and less able to provide a cohesive, comprehensive description of gravitational phenomena and the large-scale structure of the universe.
This has profound ramifications, limiting the sophistication of space technology, the ability to model celestial mechanics, and the depth of our cosmological understanding. Without the insights provided by general relativity, crucial discoveries such as the expansion of the universe, the existence of dark matter, and the predicted detection of gravitational waves remain elusive.
Nonetheless, Fichte's philosophical conception of gravity as an emergent property of space-time continues to exert a strong influence on scientific thought in this timeline. It represents an alternate path not taken in our own history, highlighting the contingent nature of scientific progress and the importance of foundational metaphysical assumptions in shaping our understanding of the physical world.
