  We study physics from a fractional dimensional perspective. It is considered
that the whole space is not only integer dimensions but also a superposition of
spaces between integer dimensions. Space-filling between integer dimensions
makes a fractional dimensional space. This happens through a rotation of the
integer dimension by the fractional derivative operator (local part) to sweep
all spaces between two integer dimensions. Then, we introduce six axioms which
they can help us to build a mathematical framework for study physics from
fractional dimension point of view. Afterward, three scenarios such as static,
linear and quadratic trajectories are demonstrated. Where moving with linear or
quadratic trajectories in fractional dimensional space corresponds to an
inertial framework or accelerated system in physics, respectively. Also from
this opinion, it is realized that the coupling of space and time (space-time)
happens through the dimension platform with an interconnection role where we
call it space-dimension-time. Finally, the wave equation is derived from a
fractional dimensional point of view with a linear trajectory in fractional
dimensional space. And the behavior of electromagnetic wave in lossless and
loss mediums, Doppler effect and gravitational red (blue)-shift are also
demonstrated from fractional dimensional aspect.
