But it _DOES_ happen in real life. There are numerous experiments that
physically implement the twin scenario, and it is _OBSERVED_ that the
"twins" are not the same age when rejoined.

This proves the twin's paradox does not exist in real life. <shrug>

Isn't this what people have been saying all along? The twins paradox
is not an actual paradox.


It's just that in our everyday lives we don't notice the nanosecond
effects of an airplane flight to Disney World and back....

The twins can age differently. This does not mean the Lorentz
transform is valid.

Of course not. All it means is that there isn't a paradox.


If each twin observes a time dilation of the other, the other must
observe the same amount of time dilation of the other one. This is
dictated by the principle of Relativity.

That would be true, except the twins are not symmetric. One has to
accelerate.


According to the Lorentz transform, each twin must age differently and
with the same amount of the difference when they meet. Since this is
logically impossible, the Lorentz transform manifests mathematically
the twin's paradox. You (plural) have matheMagically handwaved the
resolution of this paradox for more than 100 years.

The resolution lies in the breaking of the twin's symmetry.


The metric being an interpretation to the invariant geometry after
deciding what
coordinate system should be employed to do so has been interpreted as
the geometry itself for over 100 years. Erroneously interpretation of
the metric as the actual geometry has also caused an erroneous
interpretation to the mathematics of GR.

I'm still waiting for you to supply two metrics that correspond to two
different geometries while both satisfying the conditions of
Birkhoff's theorem.


Both points cover the most basics of the mathematics. They are very
simple. They belong to the elementary school level of learning.
<shrug>

Since they are so basic, do you think you can finally tell us where
you learned this stuff?
