Perhaps if humans were to undertake a long space journey there would be another solution to simulate artificial gravity. Picture this: A large spacecraft with a huge funnel "scoop" in the front. The scoop would catch residual hydrogen to use as fuel and accelerate at 1g toward the destination. This way the crew lives under 1g all the time. At the halfway point, the crew section and the engine (not the scoop) is rotated 180 degrees and the ship is decelerated at 1 g for the remaining half of the trip. The crew still sees 1g toward their feet during the second half of the trip. I just thought of this, so there are probably a million things that make this just as impractical. (edit: like exceeding the speed of light in a short time...)

Constant acceleration at 1 g is the perfect solution - if you can find enough fuel. Trying this over any significant distance (astronomically speaking) would require a truly colossal amount of fuel if you carry it all with you, and your collection array would have to be incredibly large to gather enough on the way. Interstellar matter density is typically on the order of 1 atom per cubic meter IIRC.
