I celebrate the innovation and publication of a new model.
However, as always, I have a problem with the idea of spacetime and of
a second reference frame or/and observer. To elaborate on this issue:
In the Rutherford model, The Eff. Physic Model, now called The Eff.
Cosmos Calendar System, would require substitution for "event"
"point", as follows, in [], and of course some of the remainder would
need rewriting - and so would not feature concepts such as "spacetime"
- perhaps replacing it with "co-ordinates" - (I begin by introducing
the concept of a "point": the co-ordinate system (or observer) is a
co-ordinate system of four-dimensional points):
*\subsection{Events in Spacetime}
We begin by introducing the concept of \emph{events} in spacetime.
These are the analogs in four-dimensional spacetime of points in
three-dimensional space. An [point] is something that occurs at a
specific place and at a specific time in a particular reference
frame. We represent an [point] $P$ in spacetime by $P(x, y, z, t)$,
where $x$, $y$, $z$, and $t$ are the coordinates of the [point].
[]
If we have two [points] $P_1(x_1, y_1, z_1, t_1)$ and $P_2(x_2, y_2,
z_2, t_2)$, or $P(1)$ and $P(2)$ for short, in a reference frame,
the magnitude of the spacetime separation between the two [points]
$P(1)$ and $P(2)$ is called the \emph{spacetime interval}
$s_{12}$, []*:
Your "spacetime interval" would probably be replaced by "event" -
thereby representing movement of a body in relationship with the
co-ordinates. The magnitute of movement required to be expressed in a
calendar might vary with different phenomena from a per minute rate, a
day, a year, 100 light years, ... The movement magnitudes of any such
an ongoing event would be expressed in pages or steps of the calendar.
Different calendars would express different sections of the universe.
I believe such a calendar would express, a more formidable model of
the nature of 'Nature'.
In any case, congratulations.
Comments please?
