: We can see, rounf of us that; : Light cannot go deep water.

It is absorbed and scattered by the water in the same way as a torch light is in fog. The more water the more absorbtion and so no light at great ocean depths. Think of light as a large number of small balls (photons) moving through a larger number of balls (water molecules) and when they get near each other the light changes course (one ball bounces off the other).

: Light 'mirror' at window.

See above. If the material is just right all the balls bounce in the same direction.

: Near the gravityfield light make curve.

Light always travels along the shortest path. In a gravitaional field the path itself is curved. The curvature of space due to the earths gravitational field is too small too measure. It has been measured for the Sun and explains why Mercurys' orbit precesses by an extra few hundredths of an arc second every century.

: ETC. : This mean that light is material, and material have own moving-laws.

I am sorry but this is an incorrect jump in logic. It is like saying ships float, iron sinks, ships are not made of iron. There is more going on than you are aware.

:When light move at space, and hit other light, :what happen at both light. :- Speed decrease.

Proof of this please? You claim it is important to measure things in to find the reality of nature yet make a specious claim based on no evidence.

Interference of light is routinely measured by school kids and is well understood as the waves amplitudes interacting. There is no need to invent light speed decrease to explain this.

:- They joined together, because light are :'similar'.

It is called interference. If the frequencies of the interfering light rays are far enough apart nothing happens.

:Light dont make own 'energy' do move at space, :so it has not constant speed.

It does in a way. Light is a moving electric and magnetic field. A moving magnetic field creates an electric field, a moving electric field creates a magnetic field. The electromagnetic field creates itself and keeps moving.

:Question. :How big errors to we have at space-picture, :because we use constant, :'light speed is constant'.

None at all.

: :Am i wrong?

Yes.
