 you can observe clear light a length away between objects, vision is direct and faster than light.

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.

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.

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?
