Time is not inherently linear. It is not merely a fourth axis in a fixed spacetime model. Rather, it emerges as both a perceptual and physical construct tied to the rate of change within systems. When this rate of
change deviates significantlyuespecially in contexts involving mass and velocityuit can affect how time passes relative to an observer, producing measurable physical effects. In some cases, this may even lead to gravitational anomalies.

Traditionally, physics has treated time as a dimension much like length, width, and height. This is the foundation of the spacetime model
introduced in EinsteinAs theories of relativity. Yet there exists another interpretation that is equally grounded in scientific observation: that
time is not a fixed background, but a derived propertyua way of comparing
how systems evolve. From the perspective of thermodynamics, timeAs arrow points in the direction of increasing entropy, signifying that what we experience as the forward flow of time is actually a measure of
irreversible change. In quantum mechanics, time behaves differently than
in classical systems, often not even functioning as a dynamic operator in
the same way space does. Even in relativity, the passage of time is not absolute. Instead, time is observed to flow differently depending on
relative speed and gravitational conditions.

EinsteinAs special relativity shows that time slows down for objects
moving at high speeds. The faster something travels, the more slowly time passes for it relative to a stationary observer. General relativity
extends this further, showing that strong gravitational fields also slow
down time. These well-documented phenomena reveal that time is not immutableuit stretches and contracts in response to mass and motion. It
is not strictly linear, but fluid and conditional, dependent on context
and relative conditions. This supports the view that time is
fundamentally tied to the rate of change rather than acting as an
independent dimension.

On Earth, most of our experience occurs within a relatively stable gravitational field, and we tend to move at similar speeds. As a result,
the rates of change we observe appear consistent and synchronized. This creates the illusion of linear, uniform time. However, this uniformity is local, not universal. A practical example is the necessity of correcting
GPS satellite clocks for both gravitational and velocity-based time
dilation. The technology depends on compensating for the slight but significant difference in the rate at which time passes at altitude and orbital speed compared to time on the surface of the Earth.

When we introduce systems involving rapid motion and concentrated mass,
such as helicopter blades, we start to see more dramatic divergence in
the rate of change. Helicopter blades are made of dense material and
rotate at extremely high speeds. Although their tangential velocity is
far below the speed of light, they nonetheless experience minor but real
time dilation. These effects can be calculated using special relativity.
While small in absolute terms, they become meaningful when considered as
a differential from the Earth-normal time rate. The rotating blades are,
in effect, operating in a slightly different temporal frame from the surrounding environment.

Extrapolating from this, if high-mass, high-speed rotation can compress
local time, then it could also produce distortions in inertia and
gravity. This is similar to ideas proposed in theoretical propulsion
systems such as the Mach Effect and the Woodward drive, which posit that inertia and gravitational interaction are not fixed, but functions of
changing energy states and time. In this framework, altering the rate of
time locally could feasibly modify the experience of gravity.

Gravity, in general relativity, is described as the curvature of
spacetime caused by mass and energy. If mass-energy can influence the
passage of time, then the reverse may also be true: manipulating
timeuthrough changes in mass distribution or velocityucould affect gravitational force. This leads to the possibility of creating conditions
that mimic or reduce gravity. In other words, if helicopter blades or
other rotating mass systems can sufficiently alter their local time rate,
they might generate a gravity-like reduction or repulsion. This
conceptual model forms a speculative but not baseless approach to understanding so-called anti-gravity effects.

Some experimental anomalies, like the Podkletnov effect, have fueled this hypothesis. In these controversial experiments, a spinning
superconducting disc appeared to reduce the weight of objects placed
above it. While unconfirmed and highly debated, such results suggest that
the interaction between mass, motion, and local time rates could produce measurable changes in gravitational behavior. Another reference for this
is Eric Laithwaite, a British electrical engineer, became known for his
work with linear induction motors and his controversial claims about gyroscopes and "anti-gravity."

Taken together, these observations support the idea that time is best understood not as a linear axis but as an emergent property of changing systems. When the rate of change departs significantly from the normuparticularly in high-mass, high-velocity systemsurelativistic time dilation occurs, potentially affecting inertia and gravity. While much of
this remains theoretical, the underlying principle aligns with known
physics. The notion that localized time differentials could manifest as anti-gravity is not inherently unscientific. It is a provocative
extension of established principles and invites further exploration into
the true nature of time and its relationship to motion, matter, and the
forces that shape our universe.
