    Do you mean “c” instead of “g”? I don’t think there are a lot of “g” in interplanetary travel.

      I mean ‘g’. 1g is 9.81m/s^2. c is a speed, not an acceleration. g is acceleration.

      Not coincidentally, it’s the acceleration you experience from Earth’s gravity, but it doesn’t have to come from gravity. Astronauts routinely experience 3gs during takeoff from their rocket boosters.

      If you were in a rocket that accelerated at a constant 1g it would feel like Earth’s gravity, even in space. We don’t have any rockets capable of producing 1g for years.

      No, g is a measure of acceleration equal to Earth’s gravitational pull at the surface of earth (approx 9.8 meters per second per second). ‘c’ is the speed of light, you can’t accelerate with a speed.
