I was wondering if all particles of a given type are considered to be exactly alike.

I understand your last sentence. Einstein was complaining about the math complexity for general relativity. perhaps math simplicity can be a false prophet? I don't use math much and I feel more at ease with anisotropy than isotropy with regard to light speeds, as it seems closer to a pre-SR...

if light would be traveling at different speeds in opposing directions, what would the implications be? Do you think it is possible?

so if a clock at the mirror is set back in time by the right amount, it makes the outgoing time less and the light speed greater, and increases the travel time of the return trip, lowering its speed, to c if it is done right. if this is what would happen by definition, just to get equal...

the speed of light on the outgoing trip and on the incoming trip needs correction to c so as to satisfy the observer that the ruler is experiencing speed c in both light directions. the ruler is longer but shortened (has shorter units?) and time slowed. that would have the same effect on the...

is there a way to start with c+v or c-v that one would have expected and then produce the c by means of a verbal description or simple math as to why or how it happens?

there is a difference. i am not asking about an observers own c. i mean how can observers in motion explain the c speed for relative moving objects. On the face of it, the light speed would seem to be more or less than c for others, but those others measure there own at c. the question is...

Ibix said above: "if you mean "what rate of change of separation will some other observer (moving relative to the flashlight) measure between the flashlight and the light it emits", then from this perspective the distance between the flashlight and the light it emits will grow at c-v, not c."

light speed is always calculated. how is it calculated to be at c when for all moving observers it seems not to be at c (for that object).

I think it is being said that changes to a moving object are only apparent to observers in motion relative to that object; the moving object itself can see no difference in itself. what does a moving observer think or do that would explain how objects, moving in relation to said observer...

If a flashlight varies in speed, what becomes different about the flashlight so that the speed of light stays the same for the observer on the flashlight?

does this mean that the speed of the photons in relation to their sources can vary if the source's speeds vary?

if photons are traveling on the same path, and in only one direction, are they sometimes passing each other? Or are they staying in sequence? Assume the sources for these photons are variously moving in relation to each other. .

Thanks Bystander. After looking around for awhile, I found this free article on PEC cells titled Monolithic cells for solar fuels: http://pubs.rsc.org/en/content/articlepdf/2014/cs/c3cs60424a
