Anything moving at "c" does not experience time.
The reason the video is not 0s long is that there is an acceleration phase, and the ship never quite reaches "c", and then a deceleration phase.
If you were to PoV a photon's perspective, the journey would be instant.

Yes, just slowly from an outside perspective. ie, Time dilation.
From the perspective of the traveller actually doing "c" though, birth to death is instant as long as they are always at "c", regardless of distance travelled, regardless of any outside observed metrics.
Effectively, we always "move" at "c", but in "space-time". At true rest, we move at "c" through time only (theoretical only, we cannot be at rest in reality). As we move in 3D space, we trade from time to space, taking a fraction from "c" in time, to a fraction in 3D space. The two speeds must always add up to "c", so moving through 3D space at "c" makes time=0. This is why "c" is a hard limit, because you can't make time negative.

ACKCHERLY... The term is "geek". People are ignorant to this, and it's very silly. "Nerds" are the "fandoms" of fictional shit, like Star Trek etc or those little pieces of candy... They know every little detail about that sort of nonsense. Geeks are more technical, engineers and such, and know real things that matter that are often beyond the comprehension of the average Joe.
HTH!

Yes, thanks for that Einstein. I was of course ignoring the time dilation for comedic effect.

99% of physicists agree
That they're probably wrong. It's the easiest way to still be right all the time.

i think you'd have to define both time and experience to say that statement with certitude
einstein defined time as only relative to local frames of reference, they can only be synchronised relatively between two clocks, and a clock is really just ordinal events, be it microseconds or hours. therefore the photonic excitation of the energy field is an event whose location can be referenced in spacetime relative to measuring events in another location in spacetime (for example, the start of a second on a clock). they all exist in space time, the clock, the photon, the observer. none of them experience time. the observer just deterimines the various events ordinal spacetime position, the observer themselves are merely an ordinal sequence of events. "experience" is just a label for that cascading causal sequence of events emergent from the complexity of evolved brains. one event causes a single synapse to fire reinforcing a calcium potassium ion channel as a causal event in ordinal sequence and we call this "experience". there is no real time, there is no real experience. our brains "experience" the arrow of time as forwards because that's what "experience" is, it's a tautology, what emerges when you run that tape forward on the brain. But you could also say we "experience" time backwards, it's just that when you play the tape backwards "experience" could describe a process where reinforcement triggers a reverse firing of the synapse back to the potential state. Both could describe reality, as could not playing the tape at all. Reality is a tapestry, relative events in space time where past, present and future all exist at once. "experience" and "time" are just labels our brains have made, rather than reality.
the photon doesnt experience time, nor does anything.
