Question Isn't expansion just a lorentz transformation through time?

[Gibsense]

I stand corrected on Minkowski , thanks for confirming Einstein was a fake and stole peoples work ! Reminds me of somebody else too , present science .

Everyone stands on the shoulders of those who went before - even you.
And then he went on to describe General Relativity. I suppose you think he stole that also (?)

Einstein was a pattent clerk so maybe he read it then denied the pattent , I don't know because I wasn't there!

Relativity isn't that difficult !

I do agree with you that my advanced work stands on the shoulders of ''giants'' but these giants I have to correct in some areas !

I am relieved you assert you were not there guiding Einstein's hand.
Your advanced work is what? I must have missed it. Let's discuss it (?)

Expansion is a relative motion vs a real or absolute motion.

because the vector direction of expansion is dependent on the observers location therefore the expansion is not a real expansion, just a relative measurement.

• Real motion:
  • Represents the true displacement of an object in space.
    
    
    
  • Measured independently from other objects.
    
    
    
  • Considered as the "absolute" motion.
    
    
• Relative motion:
  • Describes how an object appears to move compared to another object.
    
    
    
  • Requires a reference point to calculate the motion.
    
    
    
  • Used to analyze the movement between two objects in a system.
    
    

expansion is not real.

I don't understand how the conclusion arises and I am not confident that the word 'real' - used thrice - is meant the same way in all instances

real motion is the true displacement of an object in space.
real motion can be measured independently from different objects.
expansion does not fall into the realm of real motion, as it does not fit the definition.
the expansion displacement vector is relative to the observer. each observer calculates a different direction vector of expansion . Therefore it is only a relative measurement with the appearance of motion, not a real motion.

I think I understand you to say that real motion is travel through space and that separation motion due to expansion is different,
The assertion that separation movement (universe expansion) is relative is not true. You will find that any observer in the known universe will have the same measure for the Hubble Constant.

Motion is a vector quantity because it requires both magnitude (how far something moves) and direction to be fully described;
the vector direction is different for every observer.

if two observers are on opposite sides of an object, the object will appear to move in opposite directions. Expansion motion is certainly relative.

 

[Gibsense]

if two observers are on opposite sides of an object, the object will appear to move in opposite directions.

Not if they have a common reference frame

 

[Greenlight]

I don't believe this to be true.

an accelerating/decelerating observer would measure it differently.

 

[Greenlight]

Not if they have a common reference frame

I don't see how that is possible.
can you explain how this could be possible?

expansion is always in the radial direction.

how can two observers in different locations, which are opposite sides of an object, measure the same vector direction of that object as each other if both see it moving in a radial direction?

 

[Classical Motion]

Flip one observer.

 

[Greenlight]

Flip one observer.

how does orientation affect expansions direction when expansion is always radial?

how does parallax work if two observers in different locations can measure the same object as the same vector angles?

 

[Classical Motion]

Pardon me, it wasn't about expansion, it was about a rotating frame.

 

[Greenlight]

The only time two observers in different locations could record the same vector direction of expansion is if they both on the same side of the object being measured and lined up perfectly. Otherwise there will be a different vector direction of expansion. And even in this case the speed of its velocity vector will be different.
the motion is relative.

Ah, let's get on the same page. Is this not how Relativity allows agreement?

 

[Gibsense]

Somewhere - which thread? - I said all observers in the universe would measure the Hubble Constant as the same value. With no qualification.

My statement was incorrect. My apologies.
