      None. None!

      G-forces are due to *acceleration*, which is how fast you’re changing speed. If you stay the same speed, you don’t feel any g-forces (unless you change direction, of course, like when you turn in a car). Sitting in a car going along the motorway at the same speed feels the same as sitting in a car standing still, right?

      Although if you’re travelling at light speed and hit something, you’d explode, so be careful of that.

      Once you got to the speed of light, none. Getting to the speed of light would either kill you from the G-force or take an infinitely long time.

      If you were traveling in a straight line at the speed of light you’d have no G-force. BUT! If you tried turning a corner the G-force would be massive. You’d probably go splat…
