Almost correct (i.e. not cannonballs) but only after we have
successfully cracked the light barrier which, as Einstein pointed out,
is a result of SR that is invalidated by the presence of a
gravitational field.

Light is only measured by any traveler to be c only in accordance with
the theory that his rule incurs length contraction and his clock slows
down when he is moving relatively to the source of that light compared
to when he was contained in the same RF as the source.

According to SR if a source emits a beam of light the front end of
that beam is moving at c away from the source however if the source
accelerates in the same direction as a beam of light that it is
projecting the front end of that beam as well as its constituent
photons are not moving away from the source at c. Special theory does
NOT apply to accelerating reference frames!

If a light source is illuminated for a brief period of time the end of
that beam represents 'a rear' that, if we are moving with superluminal
velocity, can be 'run down' i.e. overtaken.

No doubt in your opinion - not in mine which is that individual
photons of light are 'quantum packages of energy' that are not 2
dimensional.

In the 'classical' 'ratification' of time dilation - the light clock -
that beam is not oncoming light and there are no photons smacking into
the observer. It IS a purely hypothetical depiction as is mine which
involves a observer looking at a far distant source that is projecting
light in both direction none of which is moving toward or smacking
into him.

============================

  The only thing any observer ever 'looks' at is the received [message] 
striking immediately at and in the eye or upon the sensor. The observer 
'looks' at nothing else in the universe, observes and senses (except for the 
'perceptions' of the mind's eye) nothing else in the universe. 'Far distant 
sources' involved in any kind of current events -- except for just certain 
[very singular] sources and current events -- are things unobservably 
futuristic to every observer even slightly distant from the source, much 
less the said "far distant". Your light beam exists in the universe as 
sequentially offset / offsetting space-time emissions (2-dimensional 
single-sided only entities) rather than one:

(S(t11))>t10||t9||t8||t7||t6||t5||t4||t3||t2||t1>(R(t11))

Where (S) is the source emitter emitting and (R) is end receiver receiving, 
and (t11) herein representing the local form of cosmological constant 0 
((S(t11)) equaling (R(t11)) (0 equaling 0). The only part the observer 
(R(t11)) is observing is 't1'. The observer most definitely does not observe 
(t11||t10...t2||t1) as one observed and observable event...as you implied 
("...an observer looking at a far distant source [[THAT IS]] projecting 
light...").

  To travel to or toward the source of light's emission, as you see from the 
above, the traveler must ascend time -- herein light and light time -- t1 to 
some t(x) beyond (S) and (R)'s represented current event time of (t11)....a 
distantly observed destination in the "observable (historical) universe" (-) 
to an arrival at a previously unobserved -- previously unobservable --  
destination point space (0) via path (+) (a 'future past' or 'future 
history' relative to the traveler / observer). The traveler's departure 
point, once space (0), is now a distantly observed history (-), a distantly 
observed time (-), in the observable (the historical) universe (-(-)-) as 
far as this traveler / observer (0) is concerned. The departure point now 
being nothing more or less than a [far out-of-date] light speed transmitted 
message in the beholder's eye.....

  .....as is all of the 1-dimensional string of the "observable universe."
