Considering the twins paradox, which one would you be?

The one that flies away will come back to see his/her twin 'AS HE/SHE WILL BE IN THE FUTURE'.  So, depending on your view of this ... you can decide if you want to know or not.  For example, if the 'older' twin is now sick with diabetes or Alzheimer's or some other 'environmentally driven chronic disease', it might be helpful and motivating to you, enabling you to 'change your ways' and reduce your risk for the same outcome in life!\n\n\nNote: this idea is based on the well accepted principle that most chronic diseases are not caused by genetics but are a result of a 'mismatch' between the individual's genetics and environment.  Therefore the returning twin can see that his/her sibling had a 'mismatch' in his/her environment that did not work well for their 'common' genetics.\nBest wishes.

No one possesses the wisdom to know what is best in the long run.  We might succeed in making our lives more comfortable but cause unbearable suffering to some future generation.  Or we might change the forces that caused us to be born at all.  In which case we would not be born to make the change and cause a paradox.  \nWhich might be cool.

I often tell people if I was any happier I'd be twins.\nMy faith in God and Jesus Christ satisfies.

You see yourself differently than other people see you. I want to see how other people view me. It would be cool to meet my twin!

there are some times that a women drops two eggs instead of one and if she had sex in that time frame with two different men then she could very well have a set of fraternal twins that have two different dads

A paradox is a situation in which something seems both true and false.  For instance, we know there are rabbits but talking, etc.  Good article on Wikipedia...

I'm a twin, and we do have similar traits, we think on the same wavelength, but our personalities differ, i am outgoing, my brother is more laid back. So, i think it's in the genes.i'm like my dad, he's like my mum.

I'm assuming you mean identical twins?  I have identical twins and was discussing this with a friend of mine who is an identical twin.\n\nIdentical, or monozygotic, twins come from the same fertilized egg which splits.  They have the exact same DNA.  So, if a set of identical female twins were to have children with a set of identical male twins then the resulting children would genetically be brothers/sisters.  (Emotionally/legally/etc they would be cousins.) They would look as similiar as other sibilings do.\n\nMy identical twin friend said her and her sister used to want to marry identical twins just to see what would happen.

It's probably best to look at this via the space-time geometry, which does not change. Both twins have paths in space-time and the amount of time they experience is related to the Minkowskian arc length of their path (the pythagorean relation has a negative sign put in). The twin on earth has a straight path in space-time, while the other twin has a path with a corner. This means that the earth-bound twin is in an inertial frame the whole time, while the other twin is not. So, while the they are both accelerating with respect to each other, only the twin in the spaceship actually experiences the force from an acceleration. The twin that actually feels a force of acceleration will be the one that ages less. Note that the spaceship twin need only feel that acceleration for an instant, but that is enough.

The twin paradox, sometimes called the "clock paradox", stems from Paul Langevin's 1911 thought experiment in special relativity: one of two twin brothers undertakes a long space journey with a high-speed rocket at almost the speed of light, while the other twin remains on Earth. When the traveler returns to Earth, he is younger than the twin who stayed put. Or, as first stated by Albert Einstein (1911):\n\nOrigin of the Paradox\nThe strange result of twins of different physical age was not the central problem of the "twin paradox". As early as 1905, Einstein predicts that a clock which is moved away and brought back, will lag behind on stationary clocks. Einstein calls that result "peculiar", but the calculation is straightforward and the example is not presented as paradoxical, despite his suggestion in the introduction of the same paper that only relative motion between objects should matter.\n\nIn 1911, Langevin discusses the evolution of the concepts of space and time in physics and presents the principal aspects of special relativity. He suggests that special relativity implies the existence of a stationary ether and states: "Every change of speed, every acceleration, has an absolute sense". To stress this fact he provides several examples such as that accelerated electric charges emit electromagnetic radiation. He proceeds with a thought experiment similar to the specific example above. Langevin next explains the different aging of the twins: "Only the traveller has undergone an acceleration that changed the direction of his velocity." According to Langevin, acceleration is here "absolute", in the sense that it is the cause of the asymmetry (and not of the aging itself). Also in this discussion there seems nothing paradoxical about it.\n\nHowever, it was Einstein's objective to show that all motion is "relative", and he thought to have reached that objective with General relativity. Thus he stated in 1916, in his introduction to that theory: "The laws of physics must be of such a nature that they apply to reference systems in any kind of motion" (including accelerated motion). And he concluded about two relatively accelerated systems K and K': "From the physical standpoint, the assumption readily suggests itself that the systems K and K' may both with equal right be looked upon as "stationary", that is to say, they have an equal title as systems of reference for the physical description of phenomena." In other words, all observers are equivalent, and no particular frame of reference is privileged.\n\nThe perception of paradox is rooted in a misunderstanding of the meaning of equivalent frames in relativity and therefore arises in both SR and GR. The Principle of Relativity states that the mathematical forms of the laws of physics – say, mechanics and electrodynamics — are identical in all frames of reference independent of their relative motion; i.e., all frames are equivalent in this restricted but important sense that the laws of physics are invariant from one frame to another, whether the frames are accelerating or not. In the twin problem, although the respective frames are equivalent in this sense, they are not dynamically symmetric since only the traveling twin experiences acceleration. However, if one assumes that the frames of the traveling and stay-at-home twin are dynamically symmetric and confuses dynamic symmetry with equivalence (and perhaps, additionally, falsely infers equivalence to mean identical calculations in all frames), one erroneously concludes the same result for each twin's time dilation as calculated by the other twin; i.e., one expects the traveler upon return, to have aged more and less than his twin – which is clearly impossible. In this connection, it is important to understand that relativity does not claim that all observers make identical measurements when observi

Nature and nurture both play big roles - you can't really isolate one or the other.  And you can't really say that one or the other would make a random person smarter.  If you really want to learn more, check out some studies of identical twins who were raised separately.

There is about a 1 in 10 billion chance that someone would have the same dna as you, unless you have an identical twin.  Scienctists don't like to say "never", but that's really close.

To the world you may be only one person, but to one person, you may be the world.\n\nThat's something to think about.

The dumbest question asked of me isn't when I'm at work.  It's when I'm out with my year old twin daughters, who are the same size and not identical, but look almost identical.  People stop, drop their jaws and ask "Are the twins?"  I always want to respond, no dumb*** one is real and the other is an illusion.

I would: if that person was not a pathological liar, such a lie would be quite pathological: I'd immediately self-diagnose that!\n\nYes, I know, it's a paradox.

Ask yourself, which one do you realate to more.
