It's a misnomer...It isn't a paradox.
I'm not going to address all your lengthy post above rivers, but the point is, is that acceleration and decelleration are part of the journey for the travelling twin, which was sort of forgotten when the analogy was first raised.
That aspect removes any paradox [it just cannot happen] and points to the theoretical possibility of time travel, which happens everyday anyway, with non human entities, and at an insignificant rate with human entities.

Now you know
??
No, I've known for years....I've spoken about it before here.
You need to be more observant and less anti anti just for the sake of it.
I'm not anti for the sake of being anti , I disagree because things don't make sense and I'm open to different perspectives and I've thought about it for a long time
Such as time travel , which I have given all my arguments against
And I have given evidence for. [at least of the twin paradox kind]
Which is not time travel
Bullshit.
OK, I'll give you the benefit of the doubt.
A few questions....
Which part of mainstream cosmology does not make sense?
What do you theorise differently, and where is the evidence?
I'm also for different perspectives, like for instance, Alien origin UFO's....I would dearly love that to be factual....but all we have is indirect evidence at the best, and delusional witnesses at the worst....no hard evidence to support it.
And finally, if you or anyone else on any other science forum, had anything invalidating the incumbent model, get it peer reviewed. and please don't start raving on like our conspiracy friends, re glass towers or Ivory towers of the mainstream, with no chance of a look in.
I mean it happens every day, but through the right channels, with people with access to state of the art equipment and probes.
That's just the way it is.
How is the twin paradox , time travel ?
The paradox is about speed and perspective on aging , thats not time travel to me
There is no going back to the past or future within in this for any adventurer
Well tell me, what would you call it?
if I ventured off into the galaxy at 99.999% c, and returned to Earth 12 months later...I have aged 12 months biologically, and all physical apparatus including clocks, on board with me, have also aged 12 months.
But lo and behold, I hop out of my new age space ship, and find I am on Earth 225 years in the future...
Tell me again rivers, that it isn't time travel.

The thing is , its just your biology that has been slowed down and mechanisms
One yr at light speed doesn't change 225 yrs of Earth history into the future
Yes, didn't I say that? It's a FoR thingy, but with both being real and valid.
????
One year at 99.999% c, in the travelling twin's FoR, sees 225 years in the stay at home twins FoR.
It's the future for the traveller, certainly......with the stay at home twin, long since dead and buried.
Why are you having difficulty accepting that?
[I won't raise any anti mainstream agenda at this time]

Did you calculate the g forces you would experience for those twelve months to accelerate to 99.999% c. Assuming that you reach that speed, you would have to accelerate to reach that speed in 6 months, because you would have to accelerate at the same rate to stop.
Much less the materials for a spaceship to reach that speed,,,, your biological body is what it is,, and I just don't think it could stand up to that kind of acceleration. That's why it is woo science.
Those conditions were not factored in as well as other scenarios I would Imagine.
It was afterall an exersise in showing that time travel was theoretically possible....and it succeeded.
Woo science??...Obviously you are drawing a long bow, I mean flying at the speed of sound could also have been labeled woo science at one time.
The thing is physicist/cosmologists at many orginizations including NASA, JPL and John Glenn Laboratories are doing reserach on that and similar concepts already.
I personally, see anything allowed by the laws of physics and GR as possible, given time.
But there are obviously aspects of woo science being discussed in alternative theories, that you could vent your displeasure at, if you are so inclined.

Time travel is impossible. Forget GR and twins for a moment. You have to work with ALL the rules of physics. The physics of thermodynamics, materials, etc, etc, Do you have any idea of what happens to matter when it reaches relativistic speeds? At the point when it's kinetic energy surpasses it's rest mass energy, it no longer is treated as matter, it has the properties of radiation. (And that's just at the particle level, when you try to keep a spaceship or person intact at relativist speeds, they fall apart.) You and your spaceship will become a ball of plasma long before you reach relativistic speeds.
You would be better pursuing cryo-stasis if you want to see what things are like in 225 years. That's at least a possible thing.. Spaceships, machines and people at relativistic speeds is GR woo, but there are other physics you aren't accounting for.
It goes without saying that the whole exersise would need much consideration and research, including materials g forces etc...In actual fact the exersise I used was simplified for obvious purposes, as many science analogies are. I would have really thought you would be aware of that.
If I had a number for NASA I would give it to you.
You could notify them of their impossible task.....
Maybe, like me, they do see theoretical possibilities in anything not disallowed by the laws of physics and GR.
It's dumb, calling that woo science.
