Subject: CRYONICS Time travel


Time travel is potentially the most interesting subject in physics and 
society (at least as I see it!). there i suggest a time machine with 
stochastic property: it take you at any instant and carry you in the far 
future without notice. That time machine is a modified car. The idea is not 
from me, it was exploited in the movie set "Back to the future": Here, a 
car was able to travel in time when it reached 88 mph in a city street.  I 
am no interested in the "back", so I don't bother with the travel in the 
past.

My contribution holds in that: Most of the time machine specific hardware 
needs not to be included in the car. That solve many mass and energy 
problems. To explain the working of the system, I take again the Langevin's 
twin paradox well known in relativity. There are two people (if they are 
not twin, there is no problem), one stay on the road border and another 
goes in the car. The driver run it at 88 mph in a city street and, for him, 
goes instantly to the future, say the end of the 22th century.

Following the Spielberg's movie, the future technology is included in the 
car so that it get new capabilities, for example the back time travel 
option.

Now, for the street border observer, the things look somewhat differently: 
At 88 mph in a city, the car crashes into the nearest obstacle and kill its 
driver, fortunately, this one has a time machine link, a card from a 
cryonics organization. For the outside observer, the driver's corpse is 
carried to a hospital and then to a cryonics storage facility where he will 
remain frozen for many years, two centuries in the above example.

There are two main conclusions: First, when you are in the movie business, 
you can get rich with a cryonics idea, if you don't speak about cryonics; 
second, any cryonist is a potential time traveler with no previous notice. 
If you are in that last category, then some centuries in the future is may 
be only some day away for you... or some years, certainly not some 
centuries.

Why is so few interest in tomorow in the cryonics world? Why is it seen as 
an unimportant question,at best, an irrelevant one for most? The problem is 
evacuated with a simple idea about retraining, with the assumption the 
difference between tomorow and today is no larger than what can be found 
today in the gap between different economical level. That kind of (no) 
reasonning has all the probabilities to turn plainly wrong.

There is a worst case: assume you are a cryonist subscriber, you are 
storred in LN2 for centuries and when the technology to live you again is 
on the market at an afordable price, the world is so different of all you 
have known than you can't be retrained. You are then thawed out and 
discarded. You may even not get a try period: from all your writting, 
behavior and past life an expert system can be built to simulate your 
personality. If that "zombi" can't adapt to the new world, the cryonics 
operators of the time would know you can't be retrained.

Would it not be interesting to start now to build such "zombies" from 
neural networks? we could subject them to very different worlds and test 
our capabilities to undergo a large retrainning. Well, it cost nothing 
today to discard such ideas... If you want to take the risk. For me, I 
order a neural net.
