Beauty is the splendor of truth.

If a theory is not beautiful, it is not true.

We are therefore going to talk about a sensitive subject, the notion of 
relativistic aberration.

A cube is placed in front of an observer, the yellow front side of which 
is the only one visible.

<http://news2.nemoweb.net/jntp?QsysQnpetTSlB_zDsjAhnCKqnbg@jntp/Data.Media:1>

This face is 60 meters away, and point M of the cube, relative to this 
observer, is exactly 60 meters away.

Another observer placed in R', with relative speed Vo=0.8c in the x'ox 
direction, crosses the first observer at the same place, at the same time.

For the moment, we are not looking for anything too complicated, namely 
what will become of the entire cube.

No.

We breathe, we breathe, we go very slowly so as not to fall into a number 
of hidden traps or false concepts.

We just ask, to start...

Where will the point M' in R' corresponding to M in R be located?

Note that in Hachel, two joint observers have strictly the same vision of 
the universe (but with an aberration in x). Everything that is seen by one 
is seen at the same moment by the other; everything that is seen is seen 
by the other and vice versa; nothing that is not seen by one can be seen 
by the other, and vice versa.

This is very important to understand.

A contradictor who already comes to doubt, would show that he already 
completely misunderstands SR as it should be taught.

R.H.
