There is nothing 30 million light years away for the photon.



I have to repeatedly tell you that there is no distance for the photon.

The planet in our discussion was 30 million light years away from the photon. You guys have to make up your mind. Either 30 million ly is a distance or it isn't.

I didn't ask you about distance again. I asked if it takes the photon time to travel the 30 million ly between the star and the planet, or does it get there instantly?
You keep saying there is no distance for the photon.

So since there is no distance for the photon in your theory, does it take time to get from the star to the planet or does it get there instantly? It has to be one or the other.

Why won't you just give an answer for a straight forward question - Does it take time or is it instantly?

False. There is nothing 30 million light years away from the photon. There is no distance. Period.

Distance only exists for frames of reference below the speed of light. Even then, a distance will be different for observers travelling at different speeds as you were already shown.

There is no distance for a photon, so it is nonsensical to ask about travelling a distance.

Try again, think about how the angled slit ''bottlenecks'' the incident ray.

They don't bottleneck anything. They either pass through the empty space or they collide with the material in front of them. The slits are empty space so they don't interact with the photons. Only the material around the slits absorbs photons as well as the photosensitive screen on the other side of the slits. You have to interact with the photons in order to have an observer effect.

You keep telling yourself your memories, I suppose it doesn't hurt physics.

We observe an object travelling towards the Earth that is 1ly away . The object is travelling at 0.5c towards us.

The object takes 2ly to arrive, if we were seeing that object in the past, it would not arrive in 2ly, proving ''you'' are full of beans and are incompetent at ''your'' job.

As an FYI......you technically never see anything as it currently is, as light must travel from the object to your retina and then an electrical impulse must travel to the brain, and the brain then interprets the signal. True, the time is infinitesimally small, but it does exist. You are always seeing things as they were, not necessarily as they are.

How long does it take for electromagnetic radiation enter your eye ?

sorry, I don't have the math skills to tell you. Also, you need an exact distance measurement from the surface of the object to the eye, so, it depends. But it does take time. The photon can't be at the position of the object and inside your eye at the same time.

But the electromagnetic field can be.

So if it's no distance for the photon, does that mean you are saying it reached its destination 30 million light years away instantly? I have to repeat my question because you didn't choose between time or instantly.

In which frame? Be specific...
