I want to point-out that this following response is not a challenge against the fact that space-time is actually distorted. Nor is it a challenge to the mathematics which can prove this. It's a challenge to our vision of 'reality'.

The Earth, the Space twin and the Nightsky are in three different frames of reference.
How does the night-sky have a frame of reference? Its a whole. Its own frame of reference is the observer(s) who sees it.
The frames of reference - of relevance - are that radial I mentioned, and the observers upon 'it' who are looking at that nightsky.
If you consider the universe as stationary, then the Earth is moving at 30km/s, and the space twin at c/2 relative to it respectively.
So: All observers on Earth are measuring the velocity
of that Earth, relative to everything else.
However; it should be noted that the velocity of all observers who were born on Earth, is gleaned in relation to that Earth. The Earth is used as a universal-frame of observer-motion. Agreed?
So; any
observer from Earth would actually be judging motion in relation to his understanding of velocity, gleaned from his own velocity-relations with the Earth.
Hence, the velocity of any observer is wrt Earth. That is our true frame of reference, when defining velocities.
So; would it not be more-correct to say that the Earth is moving at 30km/s, relative to everything else (which is really moving in relation to that Earth)... and that the space-twin is moving at c/2 relative to the Earth?
If the night sky has a different realtive velocity to each, they cannot see the universe as behaving in an identical manner.
But how can the night-sky, of itself, have a different relative-velocity to each, if they share the same radial of existence?
I'm not saying that it can't, or that it doesn't. All I'm saying to you, is that these things are happening within the minds of individuals. That's why I keep pointing-out that I don't disagree with the math or anything. I'm just trying to show that this is a mind-reality, and am thus challenging materialism - not science. So please have a serious think about my comments.
For the Space twin everything is normal.**It is the universe around him that has changed.**
But my scenario doesn't allow for this comment. The spacetwin is aligned with the Earth and the Sun (in this scenario). And it's impossible to see a different version of the sphere-of-view from somebody who shares the same radial of existence,
unless your mind is playing tricks with the light, so to speak. And it just so happens that this is exactly the case; for 'time' and 'space' (the personal-experience of them) is distorted, as we try to move amongst the light-things which we can see. Our motion/acceleration against the light-things produces a distortion in space-time. And yet, we haven't moved at all in relation to any light. How can we have done this, when the light hits us at the same velocity, from every direction, regardless of our own velocity in relation to the things which we can
see?
Our relationship with light is static. We cannot move closer to it, or further away. Hence the universal perception of its velocity-value means that we do not move in relation to light. We move in relation to something beyond our observed-perception. We move in relation to conceptual-absolutes. Entities of the mind. We move amongst the reasoned-backdrop of a mind.
Einstein's theory is really a theory about how the observer gleans 'motion' (velocity) in relation to Earth, and then proceeds to judge the outer-universe within the context of this intimate-relationship. Einstein's theory is really centred upon the observer himself, because our whole understanding of motion is gleaned in respect to our own existence, relative to the Earth we stand upon.
The circumference of his "orbit" is only 8.19 e12 km rather than the 9.46 e12 km as measured from Earth.
It is curious that the faster you try to go, that the slower you actually go.
Here, the mathematics tell us that as the space-twin accelerates from Earth and tries to achieve the conditions of this scenario, that his orbit will be
between the Earth and the Sun (eventually), along the same radial.
Now, it is clearly impossible for the inner-spoke of a wheel to be traveling faster than the outer-spoke. So, what's really going on here? The answer is clear to see - if you've given this response serious consideration - that the harder you try to accelerate from Earth, the slower you will actually go in relation to the Earth (which is on the same spoke, further-out).
In fact, your answer confirms that any space-man who tries to accelerate from Earth and conform to the conditions of this scenario will actually fry in the sun - since if he had the ability to achieve 0.9c, for example, his orbit would place him probably inside the Sun itself. That's a scary-thought. And somebody should think twice before jetting-off at ridiculously-high velocities (in the distant-future, of course)... unless our technology of sun-cream is more impressive.
This discussion also raises an interesting question: if any astronaught was to try and conform to the stipulations of this 'experiment' and follow the radial of the Earth:Sun, outwardly as he accelerated, then at what point does his orbit become
between the Earth and the Sun (inwardly-orbit)? At what point does the outwardly-acceleration change direction
towards the Sun?
Hopefully, you'll recognise that such a reversal is impossible. A constantly-accelerating body cannot accelerate, first away from two bodies on the same radial, and then suddenly decide to go inbetween them as a result of his actions.
Actually,
reason does allow for this
if we accept that each observer's perception of the universe is unique to his own head... and that he is seeing a mindful-reality. That reality is dependent upon his actions in relation to
it. And if that is the case, then each observer is the centre of his existence. We cannot grace anything outside the observer as "the centre". The observer is the centre.
Thus at c/2 by it only takes 27310176 rather than 31536000sec to complete an orbit.
I have no beef with your mathematics. Don't forget this when you judge me (or you Tom). I'm merely trying to say that the mathematics of Einstein's work
do prove that the reality we see must![/color] be in ~a mind~. These posts are my case to you. In fact, I insist that Einstein's mathematics must be correct! I'm just saying that the mathematics point to a specific
Reality of existence which Einstein (and materialists) have not grasped from those mathematics. I.e.: that
Reality is a
Mind.
if he were watching the Earth through a telescope, he would see the Earth clocks running faster than his by a factor of 1.15...
How do you reconcile this statement with the statement "the observer experiences
normality."?
How can the observer be experiencing 'normality' when the rate-of-change of all matter (all clocks) he can observe, is different to his own clock-of-experience? After all, if everything beyond the observer has a different clock, then what clock does the observer have?
I would suggest that his "clock-of-experience" is in-built. It's a self-referential thing. An in-built mindful thing. A constancy amongst all minds. And that's why I suggest that ~experience~ of time & space is founded upon a principle given by the mind itself. A constant-principle of experience is what the mind gives/takes from each experience.
And in this case, the mind gives/takes that all motion (of the self and other bodies) is in relation to a Law which does not allow for an observer to move amongst 'light'. Yet it does allow for motion between the
things, of that light.
Meaning that he will see the Earth clock measuring 31536000 sec per orbit.
Actually; I don't think that this comparison is possible until both observers compare notes, upon meeting again. It's a relative distortion, remember. Not an actual one as observed from outside of this 'meet'.
From the Earth, things again, are normal. You would measure the Space twin as traveling a circumference of 9.46 e12 km in 31536000 sec. However, you would see the space twin's clock running at a rate of .866...
You're advocating that on Earth, it's possible to
see two different realities of the space-twin: that of his clock and that of your clock, at the same time. But since what you see is the factory of your own clock, such a statement doesn't make sense. There's only one perceived reality. There is no duality/diversity which is evident in a singular perception.
Each observer will see the same events in the Nightsky, they just won't agree as to the length of time said events take to occur by their clock.
Exactly. Which means that the reality both observers are seeing is a product of their minds; since it is impossible for many observers to see a singular-reality in such a diverse-manner unless those observer's minds are making a reality for themselves, so to speak. However; the constancy (Law) that exists amongst the diversity of all observers, shows that all observers have a
common value of what 'space' and 'time' do mean, in relation to the
Whole which the observer does see. I.e., all observer's minds have a common-~feel~ for time & space. This is what I was referring to, earlier. The whole never changes in relation to 'yourself'... and as such, experience is a constant.
The Principle of Relativity holds
Which principle of Relativity tells you that 'materialists' are right?
