The Twin Paradox is predicted by Relativity theory. The event never took place in real life, it is purely hypothetical. 

It seems strange that an effect predicted by a theory should need several different explanations, involving SRT, GRT, or a combination of both. 

These explanations all cannot be true as they involve different effects:

Twin paradox
From Wikipedia, the free encyclopedia


In physics, the twin paradox is a thought experiment in special relativity involving identical twins, one of whom makes a journey into space in a high-speed rocket and returns home to find that the twin who remained on Earth has aged more. This result appears puzzling because each twin sees the other twin as moving, and so, according to an incorrect[1][2] and naive[3][4] application of time dilation and the principle of relativity, each should paradoxically find the other to have aged less. However, this scenario can be resolved within the standard framework of special relativity: the travelling twin's trajectory involves two different inertial frames, one for the outbound journey and one for the inbound journey, and so there is no symmetry between the spacetime paths of the twins. Therefore, the twin paradox is not a paradox in the sense of a logical contradiction.

Starting with Paul Langevin in 1911, there have been various explanations of this paradox. These explanations "can be grouped into those that focus on the effect of different standards of simultaneity in different frames, and those that designate the acceleration [experienced by the travelling twin] as the main reason...".[5] Max von Laue argued in 1913 that since the traveling twin must be in two separate inertial frames, one on the way out and another on the way back, this frame switch is the reason for the aging difference, not the acceleration per se.[6] Explanations put forth by Albert Einstein and Max Born invoked gravitational time dilation to explain the aging as a direct effect of acceleration.[7] General relativity is not necessary to explain the twin paradox; special relativity alone can explain the phenomenon.[8][9][10][11][12]

It has took place in real life. That is similar/equivalent setups have been done (we did not actually use human twin if thats what you meant!).

It does not need several walkthroughs, just one. But like 
finding the answer to 1+2+3+...+100, there are many different approaches. 

Also note that there are many different setups of the TP: Some involve accelerations, some do not. Some use triplets, some do not. 

Also note that some solutions are sloppy (and even wrong!) & use ambiguous words.

I am beginning to realize that there are better descriptions of the twin paradox and worser ones. I have been needlessly misled, hope to clear that up here.

So there are explanations involving SRT, GRT, and 'geometry'. Which theory resulted in the prediction of the twin paradox in the first place, is it not SRT only?

SR takes good care of the TP if one neglects gravity & accelerations. 
For instance, the triplet version. Now, if one want to analyse the classical version whereby the traveler needs to accelerate, then SR can still be used if we analyze the situation solely from the POV of the home twin (since he is the only one that remains inertial). The conclusion will remain: traveler will return younger than the home twin. Many books that analyze this brush off too quickly the analysis and are very sloppy (like, many claim that we can just make the accelerations brief so they dont affect the total time; well, that reasoning is totally wrong, until they actually show that that is the case; they need to prove their assertion, but they dont).

False. SR handles acceleration just fine. You need to stop pretending you know what you are talking about. You don't.

> For instance, the triplet version. Now, if one want to analyse the classical version whereby the traveler needs to accelerate, then SR can still be used if we analyze the situation solely from the POV of the home twin (since he is the only one that remains inertial).

False again, there is a very good paper that analyzes the problem from the POV of the accelerating twin using SR. You need to stop pretending you know what you are talking about. You don't.

This is not true -- the twin paradox has been implemented several times, with 
results consistent with the predictions of SR. The best one is by Bailey et al 
in http://math.ucr.edu/home/baez/physics/Relativity/SR/experiments.html

It doesn't "need" several explanations, any one will do. It's just that there 
are multiple ways of looking at it. Note that this is true of almost every 
experiment one can imagine, and also every gedanken.

Sure they can. They involve different effects for different sets of assumptions 
or different theoretical contexts.

	Why is "up" up?

OK but not sure about the origins of the twin paradox - was it predicted by SRT in which case SRT must have an explanation within itself for the effect. That was what I meant. Of course one could have several explanations for an effect, for example muon decay delays.

Yes, it was first described shortly after SR was published in 1905.

In SR, the elapsed proper time of a clock moving relative to an inertial frame 
is give by
	\integral dt/gamma(v)
where t is the time coordinate of the inertial frame, v is the clock's speed 
relative to that frame (as a function of t), gamma(v)=1/sqrt(1-v^2/c^2), and the 
integral is taken over the clock's trajectory.

Since the home twin is at rest in an inertial frame, and the traveling twin is 
moving relative to it, this unequivocally predicts the traveling twin returns 
younger (less elapsed proper time) than the home twin. Actual experiments have 
confirmed this quantitative prediction with an accuracy of a few parts per million.

	Attempts to describe the situation from the perspective of the
	traveling twin are complicated. Here there be dragons. Doesn't
	matter, as the comparisons of their clocks at separation and
	reunion are unequivocal; the dragons are related to intermediate
	points and what "now" means to the traveling twin.

I do not think it is that complicated.  For the traveling twin, dx' = 0 
→ dx'∕dt' = v' = 0 → gamma(v') = 1, so they do not observe time dilation in 
their frame, but only proper time; but dx' = dx/gamma(v) – length 
contraction –, so they are not amazed at all that they travel less spatial 
distance than the rest distance in less proper time.

The traveling twin can further explain that (despite what they may expect 
from the symmetry of time dilation) the home twin is older when they meet 
again, with the *relativity of simultaneity*: *by contrast* to the home 
twin, the traveling twin changes from at least one inertial frame to at 
least one other when turning around.  Assuming for simplicity that they are 
only changing from a first inertial frame to a second one when turning 
around, a different set of events in the home twin’s frame are simultaneous 
in the traveling twin’s second frame than in their first frame, and some 
home twin’s events during that journey are not simultaneous with *any* 
events in the traveling twin’s two frames (with multiple frames there is 
full correspondance, but only during the turning).  If the traveling twin 
could observe the home twin’s clock, when turning around they would observe 
that clock jumping *ahead* of their clock (with multiple frames, gradually) 
when before it was *behind* their clock.

It basically also says so in the Wikipedia article that (IIRC) I already 
referred to, among several textbooks, I am confident, and the lines of 
simultaneity in the/a Minkowski diagram clearly show it.

I put "time dilation" and "length contraction" in quotes because they are VERY 
POOR names for the phenomena they refer to. That is, for "time dilation" time 
does NOT actually dilate, and for "length contraction" lengths do NOT actually 
contract -- those phrases refer to the clock or object in question, which in all 
cases is UNAFFECTED. Both "time dilation" and "length contraction" are really 
geometrical projections that affect how observers moving relative to an object 
will MEASURE the object, and the phrases do not capture this fact at all -- at 
face value they imply that the object itself is somehow changed, but it isn't.

MANY people who are not experts in physics get confused by these phrases, 
including many around here.

	I have said all this many times before.

"Both "time dilation" and "length contraction" are really 
geometrical projections that affect how observers moving relative to an object 
will MEASURE the object, and the phrases do not capture this fact at all -- at 
face value they imply that the object itself is somehow changed, but it isn't."

Thanks Tom, that makes it all the more clearer. This is all about a 'transformation' when describing events in a moving frame to time and space measures in our stationary frame, adjusting for the fact that speeds approaching that of light are not additive. 

But that begs the question does it not, if it is not a illusion, a real time one at that?

And again, why is GRT attempted to be used to solve a scenario that owes its existence to SRT? (Wikipedie Twin Paradox)

"Max von Laue argued in 1913 that since the traveling twin must be in two separate inertial frames, one on the way out and another on the way back, this frame switch is the reason for the aging difference, not the acceleration per se.[6] Explanations put forth by Albert Einstein and Max Born invoked gravitational time dilation to explain the aging as a direct effect of acceleration.[7] General relativity is not necessary to explain the twin paradox; special relativity alone can explain the phenomenon.[8][9][10][11][12]"

Depends on what TP scenario you are referring to. 
In the usual TP, GR is not required (when you analyze from the home twin).
But you can use GR if you want. However, if you want to analyze the situation from the POV of the traveling twin (versions where he is non inertial), then GR is required. This is well explained in the wiki page.
