Seems they've done studies on animals using some of the drugs VooDoo folks
usedto use to make Zombies. They show promis in use for hibernation. The
same effect that slows resperation and pulse enough so you look dead and
don't sofocate until they dig you up, also works for hybernation for
something like space travel.
Seems like there would be to much to do aboard a space craft to even want
hibernation. Picking landing site, training colonist with colony skills,
scanning scenery, Solving problems. Any star system colonization would
require independence from earth and also require that reproductive quality of
life in an environment of possible enclosed dimensions protected from the
elements so that colony would succeed and grow even if landfall was in an
A long time span journey solution has already been found by Einstein who
showed that should your craft near speed of light relative to earth, time
became dilated. At 50% dilation a journey a distance of 4 light years takes
two years ship time giving a velocity of twice light speed. Closer to light
speed, crossing galaxies and even the distance between them can be
accomplished in days of ship time.
Better monies be spent on engines capable of approaching light speed, -- like
the one in the link below. Independence from earth means that the eons passed
on earth during the few days are not important so distance traveled divided
by observer time giving observed velocity with a c limit is meaningless.
Unless of course your motivation for the journey is the parade of family and
friends on return to earth.
Since velocity can exceed light speed in the part of the example trip given
there clearly exists in the universe a counter example proving a light speed
limit for rockets as nonscientific nonsense and defines the limit is on what
can be observed and not what may be doable. The is no known reason to shutoff
the engines accelerating at one g for 355 days just because the rocket
The rocket becomes unobservable when velocity exceeds light speed because
observer light traveling towards earth relative to the rocket is in fact
traveling away from the earth with a negative velocity so does not hit retina
to get observed.
No paradox there but basic physical science calculating and measuring the
velocity of an object thrown from a car towards the starting point when the
velocity of the car wrt (with respect to) staring point is faster than the
velocity wrt car of the object thrown back to starting point. The object
simply does not reach the starting point. (neglect air resistance).
I propose such unobservable velocities obtained may allow the travelers to
return to earth and be closer to the age of the earth twin. Do not look for
(as they do not yet exist as a complete relativity theory) the equations
determining time variance above light speed and calculating the amount but do
feel free to derive them special relativity(SR) and general relativity(GR).
Please, do not confuse my rocket engine with those imaginary thought
experiment rockets so often found in SR and GR basic training.
It has been pointed out to me that such a velocity concept and understanding
of Einstein's theory was published by the SCI-faction author Poul Anderson in
a book entitled Tau Ceti.
