everything is effected by gravity bud, every single thing
But what I'm asking is does gravity affect muscle growth enough that it would make your muscle fibers grow straight down?

You muscle fibers are placed in a certain aligned way as genetics blueprint made them, The muscles grow, and in a vacuum (no gravity present) you would look as any normal human being looks after 20 years except with less sagging like a person in the normal non vacuum environment appears. Such as boobs for example: the muscle grows and due to the weight of the muscles and the fat, gravity, pulls it down by varying degrees of force causing them to sag and streatch over the years.
I'd say gravity is a bigger thing with posture and bones. Muscle fibers as mentioned are placed in a certain way, and grow that way.
But, since some muscle fibers are always tightened, a well defined muscle shouldn't really sag, because it's been slightly tightened. However, with age muscle is replaced with fat, although building muscle should delay/stop that.

The path and direction in which the muscle fibers are aligned is genetic. Gravity does have a significant effect on muscle growth, however. Muscles grow in response to resistance, and gravity provides that resistance. Astronauts follow specific exercise programs when in space for long periods of time to prevent musculoskeletal atrophy, because gravity is not present.
Yes, gravity does affect all of our bodily systems, but most of our physiology has self adapted to these effects. The primary example of this adaptation can be seen when our circulatory system is examined. It is a closed hydraulic system that has a physiological pressure gradient to ensure proper circulation. Without the ability to adjust and fluctuate our blood pressure, gravity would cause a greater flow rate of blood to our legs and feet, and a lower rate of flow to our superior structures such as our brain. This compensation for the influence of gravity is why "blood rushes to your head" when you hang upside down.
And muscle is NEVER "replaced" by fat. As you age, you will experience musculoskeltal atrophy. If you do not adjust your nutritional intake, you will also increase the amount of subcutaneous adipose tissue (white fat) that you carry. Your overall ratio of fat free mass / fat mass has changed, but never does "muscle turn into fat." Since skeletal muscle is contractile tissue, and fat is adipose tissue, those with a greater percentage of fat mass will eventually develop sagging skin. It is the subcutaneous adipose tissue, and the epithelial tissue that "sag," NOT skeletal muscle.
