One of the problems with conventional means of space travel (not involving faster than light) are the difficulties caused by the fact that accelerating the vehicle produces a force indistinguishable from gravity. Accelerating a ship at 10 meters per second per second would feel like earth-normal gravity.
At 20 meters per second per second, you would feel like you weighed twice as much. How could you move around without assistance?
Over the years, NASA has studied the problem of protecting people during high acceleration (both entering space and during re-entry). You would think that perfect physical specimens who underwent rigorous training and dietary regulation would do the best after the weightlessness of space travel. However, a study was performed in which sedentary and highly fit people were given a baseline acceleration tolerance test, then given 10 days of enforced bed rest. A second test was given following the bed rest.
The sedentary people were found to do better on the second test than the "perfect specimens." See the amusing article Fat Slobs in Space for additional details. Comment/Join this discussion ( 1 ) | RSS/XML | Blog This | Additional
