A spherical fluid is floating in space. The fluid is uniform and isotropic. That is, gravity has no acting on the sphere.
The sphere will be in non-accelerated frame. It is moving in a uniform linear motion through space (or is at rest). However, if the sphere moves in a way other than the above, there will be a corresponding deviation from uniform isotropy. Difference between accelerated and non-accelerated frame will not be fictitious.

Acceleration and Non-Acceleration
In weightless space, there is a starting point. From this point to six directions (east-west, north-south, and up-down directions) six points of mass start motion simultaneously at the same speed. The state of six points of mass will show the state of non-accelerated frame. These will also be an indicator for all accelerated motion (all not uniform linear motion).
If desired, the starting point can be made stationary on aether frame.

Inertial Force is not Fictitious (Summary)
Spaceship is moving horizontally with uniform acceleration. Body m is pushing against rear wall of the spaceship's cabin (A). Rear wall pushes back the body with normal force (B). A is action, B is reaction.
Spaceship is moving horizontally with uniform acceleration. String attached to front wall of the spaceship's cabin stretches backward inside the cabin, pulling body m attached to rear end of string (A). The body resists pulling force of string (inertial resistance) (B). A is action, B is reaction.
To begin with, distinction between action and reaｆction seems to be unclear.

Acceleration and Non-Acceleration (again)
Imagine a human being in accelerating passenger car and a station staff standing on platform. Now, it is a thought experiment. What if increasing acceleration g is at the level of an unmanned missile ?
Difference between acceleration and non-acceleration is not fictitious. The two are physically different. Again, because it is big problem.

球状の流体が空間に浮かんでいます。流体は均一で等方性です。つまり、重力は球に作用しません。
球は非加速フレームにあります。球は空間を均一な直線運動で移動しています (または静止しています)。ただし、球が上記以外の方法で移動すると、均一な等方性からそれに応じた偏差が生じます。加速フレームと非加速フレームの違いは架空のものではありません。
