One does see distance, distance is an axiom and provable to be there, regardless of sight I can experience the distance  of space, by moving.
Nope.....We only judge distance or measure it. Go out on a dark night and look up at the stars. Now, tell me which one's are closer to you and which ones are more distant?

Quote from: Thebox
(if photons really exist to begin with
So now you're questioning the existence of the photon?

Am I questioning the existence of a Photon?  observer effect,

can I tell which star is nearer and which is further?   I have no specialist equipment so probably not.

Maybe stars are the same size, and distance gives the sense of a difference.

I would reply, you mean measured length don't you.
And I would reply "No, check a dictionary"

Truth is Colin, it may be too difficult for him..................DENSE
It would appear so

''Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. .''

You are defining two points, that is a length and an expanding length, beyond the moving object is more distance, it only becomes a length when the object reaches x distance. Lengths are within a distance, you can't have one meaning to two different things, they are indistinguishable else.

Consider a dark tunnel, at the half way point is a light, you can observe the light from one end of the tunnel to determine a length,  but you can't possibly know the distance of the tunnel. However you can be assured it is more than likely equal to rē ,  if we say we had the light at say 1/3rd of the way of the tunnel , the distance after the light would be greater.   but the tunnel is infinite in distance revealing just lengths.

Distance - A linear quantity of unmeasured space expanding away from the observer

Length - A measured distance of space between two reflective points or a measurement of points of an object,

You asked me a question, I can only guess at a way to know, that is not ignorant that is me thinking of an answer to give you.  Consider 5 equal size circles, 2 are near and 3 are far, ''father ted'' I admit but I got the joke.

p.s I know you use magnitude and equipment to know.

Mr. Box, we have a star in our own solar system, it's referred to as the Sun. From this evidence alone, we know that stars come in different sizes. This is evidence that your answer was hasty and lacked credibility, thus the use of the term "ignorant". Ignorance does not mean stupid, ignorance is a word that defines lack of knowledge or the impetuous use of the knowledge one presently possesses.

Listen my friend, we all recognize that you're not stupid. Your mind is searching for answers and that is admirable. However, until you are willing to learn from others, your hunger for scientific knowledge will suffer greatly. We offer our answers and you continually seek to either ignore them or brush them off as insufficient and or flawed.

None of us are perfect but IMHO, the answers you'll receive here are worthy of consideration and you insult us with your cavalier attitude. I have just about had it with your obstinate positions Mr. Box. If you continue to gloss over and minimize the worthiness of my answers, I will eventually acquaint you with my ignore list.

If you continue to be disenchanted with the answers you receive from us, you might consider just not asking in the first place. Enough said......................

I think I am mistaking the word arrogance for ignorant .

I am listening to your answers that is the point, forums have leant me  and keep learning me, for self taught with only forum help I do not consider I am doing to badly.  I believe you if you say stars are different sizes I don't know any better than that and what your equipment does, that is incredible science.

An aeroplane is incredible science, things like that , just some of theory is wrong imo and the way we look at things and define things.

I would like to make it really simple and distinguishable to understand.

If there is a brick wall between yourself and the object, you can't see it. Ergo something must be travelling in a straight line between you in order for you to see it.

Remarkably, this simple hypothesis has led to the entire science and industry of optics, from microscopes and spectacles to the Hubble telescope and observations of gravitational lensing. I rather think it has legs, and yours doesn't.

I rather think your straight light misses a moving target, and your ideas of photons do not have a leg to stand on.

in your diagram at the beginning of the discussion, in the first diagram do I see the object in silhouette?

Yes , in the first diagram the observer is observing a silhouette.

Almost sir, Your  brain observes in real time, the recording of information is instant, the rate of time is zero, anything after zero is history. Your eyes and brain work like a video recorder, the clear light floods into your eyes, you are then connecting to the whole of light, your feed is continuous from A to B, you can observe clear light a length away between objects, vision is direct and faster than light.

This is cool! The idea of seeing because there is no light! WOW! I noticed after reading this discussion that most of the responses describe how light travels to the eye of the observer but I think your initial diagrams try to convey "the big picture" and the discussion  should be about seeing what is there in the light and in the dark. With all in interest in dark matter and energy this is in my opinion pertinent. If I look through a telescope and see a shadow there must be light behind the shadow and then what could be that light? I learn something about the shadow and the light source behind it, two birds with one stone if you will. Could this be a classic EPR paradox? Mr. Box my world just got a bit larger. TY.

Wrong, no action of any kind can exceed the speed of light.

No action can exceed the speed of light , really?

Why do we observe a photons at point B then that has not even entered our eyes?

How can we possibly be observing a planet or star in their past?

A photon aimed directly at a moving body  miles away will certainly miss the intended target, any sniper will tell you this.

Your welcome, I do not know what a EPR paradox is so can't comment on that, at this time, sorry.   Alls I can say is just try to imagine that the clear light in space is really dark, BUT everything you observe that is dark is an element.

When you turn a dimmer switch up on a light bulb, all the other ''light bulbs'' become  brighter.

The 5th elements lol.

This may be hard to digest, consider that when in absolute darkness you can still see, BUT there is simply no ''light bulbs'' to see. That is why we got 5 senses I suppose.

To talk ''sciency'', we observe thermodynamic beacons through  the dark.

Try a laser in the dark, observe the dot, it is still dark, we know we can not observe the incident beam or reflective beam, add smoke, we can observe the beams in the dark, the particle thermodynamic  beacons of the smoke, identifying themselves through the dark, we do not observe any light in the smoke being directly directed to our eyes, we observe the space to be still dark, we only see the beam in the dark.

Now before you say , but we need light to enter our eyes to able vision, consider in the dark there is always the ''light'' of the CBMR, so ''light'' still floods into your eyes even in the dark.

I said to a snake it is dark tonight, the snake said, ''funny it looks light to me''

We don't.

You need to do a lot more thinking before you realise why this is so, and why the light (photons) from the sun do not miss earth.
However, I'm not convinced input from me will help you, you need to discover it yourself.

Just a hint. Bullet from a gun at a moving target, curved path, whose viewpoint?

Bullet from  a gun fired directly into the sky a vertical axis, what curved path?
