Chillax Juame! : )

 

I think I see what you're saying. But I have no training in the field.

I'm not the one who chose to equate 'at rest' with 'not accelerating'. 'At rest' doesn't actually mean anything in Special Relativity, where everything moves relative to something else. since SR rejects the principle of an universal frame of reference.

But if you assume that 'at rest' and 'not accelerating' mean the same thing, as the article does (and why not? It's only a definition), then it follows that any inertial frame of reference is at rest. And that includes (unaccelerated) photons.

Then, from (1), you have to conclude that photons move through time;

And from (2), that they don't.

Contradiction.

 

Obviously the article uses a non-standard definition of acceleration since it also also equates traveling/moving with accelerating. I have the impression the author uses 'accelerating' for 'moving' (whether the motion is inertial or not), and 'not accelerating' for 'at rest relative to an universal frame of reference'. And that would be enough to make Einstein rock and roll in his grave.

Sorry Jaume, I'm just not following you. Why do you say photon are at rest? It seems to me that they clearly travel, even if it is at a constant unchangeable speed. Isn't he saying that light travels through space, but not time at all? Where does he say that photon accelerate?

I disagree:

 

(1) But, when you’re at rest (not accelerating) all of your head’s movement is through time, none of it is traveling (accelerating) through space.

(2) Since light waves use all of their motion to travel through space at Light Speed, they have absolutely no motion through Time.

 

Since light waves (photons) are technically at rest (not accelerating), we have an obvious contradiction here.

But he never says photons accelerate. I read it again just now, and I don't see what you're referring to. He talks about people accelerating though.

Funny. I've made the same hypothesis about photons being unaffected by time somewhere on this site, but it's the first time I see someone else trying to make that point. Anyway there seems to be a good bit of confusion between speed and acceleration here. Photons move at constant speed, i.e. they don't "accelerate", so this reasoning would not apply to them.
