The future is the time after the present.
Its arrival is considered inevitable due to the existence of time and the laws of physics.
Due to the apparent nature of reality and the unavoidability of the future,
everything that currently exists and will exist can be categorized as either permanent,
meaning that it will exist forever, or temporary, meaning that it will end.
In the Occidental view, which uses a linear conception of time,
the future is the portion of the projected timeline that is anticipated to occur.
In special relativity, the future is considered absolute future, or the future light cone.
What are we fighting for- a dying planet. Theres only one
Einstein framed his theory in terms of kinematics (the study of moving bodies). His theory was a breakthrough advance over Lorentz's 1904 theory of electromagnetic phenomena and Poincaré's electrodynamic theory. Although these theories included equations identical to those that Einstein introduced (i.e. the Lorentz transformation), they were essentially ad hoc models proposed to explain the results of various experiments—including the famous Michelson–Morley interferometer experiment—that were extremely difficult to fit into existing paradigms.
In 1908, Hermann Minkowski—once one of the math professors of a young Einstein in Zürich—presented a geometric interpretation of special relativity that fused time and the three spatial dimensions of space into a single four-dimensional continuum now known as Minkowski space. A key feature of this interpretation is the formal definition of the spacetime interval. Although measurements of distance and time between events differ for measurements made in different reference frames, the spacetime interval is independent of the inertial frame of reference in which they are recorded.
Minkowski's geometric interpretation of relativity was to prove vital to Einstein's development of his 1915 general theory of relativity, wherein he showed how mass and energy curve this flat spacetime to a Pseudo Riemannian manifold.
