[QUOTE 1991474, member: 9609"]It would be interesting to know what G the human body could tolerate for many months on end, may be 0 - speed of light will never be much below a year.[/quote]
We live almost our entire lives subject to 1G. So all it would mean is the spaceship would have an artificial gravity similar to that on earth for which down is towards the back end of the spaceship. Remember under General Relativity there is no difference between a gravitational field of 1G and an acceleration of 1G.
