I'm having trouble understanding angular momentum and how it relates to SR/GR. To keep it simple, if I'm in space and all matter and energy is removed (ie. reference frames) and I start rotating at a specific velocity will I feel my arms and legs being pulled out? If the only possible frame of reference is myself it will appear to me that I am not rotating at all. But my intuition tells me that any angular velocity will cause me to feel angular momentum as a centrifugal force. Lets say that my intuition is correct and I do feel my arms and legs being pulled even though there is no other frame of reference. Why is this? Would this not constitute absolute space?
