Children can understand, but you can't. If you think you can understand, then why don't you answer this extremely simple question :
Can something really go slower than 0 km/s?
In another words : will you pretend until you die that earth's velocity in September isn't the same as in March?
No, children can understand but either you can't, or you pretend not to.
Only an idiot would claim that the velocity of Earth in the HC model is the same in September and March.
In order for that to be true, it would need to be going in the same direction, while in reality it has to be going in the opposite direction.
You cannot orbit by going in the same direction.
An orbit is an ellipse, but if Earth had a constant velocity, it's path would be a straight line. Do you not understand the difference between an ellipse and a straight line?
Like I explained last time, that sign (positive or negative) indicates directionality.
For example, to describe a simple 1D case, right can be positive and left is negative.
That means +30 km/s is going 30 km/s to the right.
That means -30 km/s is going 30 km/s to the left.
Only an idiot or a liar would claim they are the same.
Likewise, if they were the same, that means that if you measure the velocity relative to another object, it would be the same.
So far example, if you measure their velocity relative to an object travelling at 220 km/s to the left, both would be 250 km/s to the right.
But in reality, one is 250 km/s to the right, while the other is 190 km/s to the right.
Again, your argument relies upon accepting that these velocities are different, yet you lie and pretend they are the same, as your argument also relies upon that. i.e. your argument relies upon contradicting itself. If you don't have that contradiction in your argument, you will not have a contradiction with the model.
i.e. the contradiction is introduced by you by pretending that 2 different velocities are the same, while also accepting they are different.
If they were the same, then 2 objects starting at the same position, with that velocity would remain together.
But in reality, they grow apart because they are travelling in different directions.
And if velocity is the same (hence the angle is the same) then there is no difference in the angles
And that is the key part, the velocity IS NOT the same. That means there is a difference in angle, which is what you are continually ignoring.
Before you even try to discuss measuring the angle between the datum line and anything, you need to first define just what this magical datum line is and how you determine where it is.
The datum line is the line which connects our astronomer (Bradley) and the real position (according to HC theory) of Gamma Draconis in the sky.
You left out the key part, determining where it is.
You are still trying to measure relative to something which you have no idea about.
It doesn't have to coincide with the Earth moving parallel to the sun in March, in case the Earth is moving parallel to the sun
The point is you are not arguing against the HC model, and showing you either have no idea what you are talking about or are just lying like normal.
Earth won't be going parallel to the sun. The orbital plane of Earth is different to the orbital plane of the sun.
In order to do it honestly you would need to accept that velocity is not just a scalar but a vector.
But that means accepting that the directionality is important, and it would destroy your argument.
Going 30 km/s in one direction is quite different to going 30 km/s in the other direction.
How is that different concerning what is of our real concern in this debate?
It is crucial.
That is because this difference results in a difference of angle, a difference of roughly 40 arcseconds, a difference you need to ignore to pretend there is a problem.
If the difference wasn't of concern then you would produce the same velocity in March and September in scenario 2. But you don't.
Once again, what is 20-(-20)?
It is 40, not the 0 you claim it is to pretend there is a problem.
This difference of 40 arc seconds occurs in both scenarios.
There is no problem for the HC model.
There is only a problem with you as you have no integrity at all and are continually lying to pretend there is a problem with the HC model. All because you don't give a damn about the truth and want to pretend there is a problem but you can't find any actual problems.
Which sign represents vector/velocity in this formula :
Θ= arctan vto/c
The vto part.
arctan(-x)=-arctan(x).
If you want to avoid the negative numbers, you need something else to deal with the directionality, but either way, if you do it honestly you end up with a difference of 40 arc seconds.
Only a moron or a dishonest liar would claim that turning x degrees to the left is the same as turning x degrees to the right.
But here you are, claiming they are the same.
So no, you the liar here, not us.
-30 km/s < 0 km/s
No it isn't.
That is because you are no longer dealing with a simple number but a vector.
Which of these is larger:
[30,0]
[0,30]
[-30,0]
[0,-30]
[21.2, 21.2]
?
They all have equal magnitude, 30.
But they have different directionality.
This different directionality does not make them less.
A velocity of -30 km/s is not less than 0 km/s.
