Question: How can two photons from separate sources
meet if their space-time locations are moving away from each other with
the space-time progression?
- The essential point here is that if an object is in motion relative
to a stationary reference system, and acquires an additional motion,
this new motion does not replace the previously existing motions;
it adds to them.
- A completely free object is moving outward from all other such objects
by reason of the space-time progression (Motion I). Two such objects
having no other motions therefore cannot collide.
- Gravitationally bound objects without independent motions are likewise
moving outward from all other similar objects (Motion I), but coincidentally
are moving inward toward all of these objects at the same rate of speed,
by reason of gravitation (Motion II). Two such objects maintain the
same separation, and therefore cannot collide.
- An object A in a gravitationally bound system may acquire an independent
motion in any direction (Motion III). The sum of all three of the motions
of this object (equal to its independent motion) may then carry it to
a point where it will collide with a similar object B.
- A photon released from object A participates in all three of the motions
of that object, and inasmuch as it is not under any restraint in the
dimensions perpendicular to the direction of Motions I and II, it is
also moved outward at unit speed in one of these dimensions by the space-time
progression. (This motion can be in any direction relative to the reference
system, as the gravitational motion is random) . The second progression
is Motion IV; that is, it is an addition to all of the other three motions.
The net resultant of all four motions is a combination of Motion III
and Motion IV. If object A maintains the same speed and direction, the
motion of the photon, as seen in the context of a stationary reference
system, is directly outward from object A. The emitted photon may therefore
collide with any object B in the gravitational system, or with a photon
emitted from object E.
