Re: The Nanometre Twin

Sue... says...

You have the traveler seeing his own clock
and the stayhome clock move at the same
rate on the outbound leg.

I don't know what you are talking about
(and I'm sure you don't, either).

During the outward trip, signals sent by Sue
arrive at Dennis at the rate 1/3 per day (as
measured by Dennis). So Dennis "sees" the
image of Sue's clock change at 1/3 the rate
of his own clock.

Signals sent by Dennis arrive at Sue at the
rate 1/3 per day (as measured by Sue). So
Sue "sees" the image of Dennis' clock change
at 1/3 the rate of her own clock.

As long as neither turns around, things are
perfectly symmetric, as the principle of
relativity would have it.

Sue is unlikely to buy any part of a story
where Dennis claims to have cheated both the
ageing process and the finite speed of light.

What are you talking about? Dennis travels for
12 days, and he gets 12 days older. Why is that
surprising? Sue travels for 20 days, and she gets
20 days older. Why is that surprising? They each
age 1 day per day traveled. Nobody is "cheating
the aging process".

The surprising part is not in the aging. The
surprising part is that there is a 12 day trip
that ends up at the same point in spacetime as
a 20 day trip.

As for your "cheating the finite speed of
light", your comment makes no sense. Why
do you think that the finite speed of light
is being cheated? All the computations assumed
constant speed of light. That's how the Doppler
shift formulas and the Lorentz transforms are
derived.
