Inertia.  Your still traveling forward and the centrafuge floor made a sudden
turn.  You have to accelerate in toward the center of the centrifuge to keep
up with the floor.

NO one knows.  Physisists would really like to know about that, or kinetic
energy, or mass.  Might be due to an interaction between space time and the
particals of an object.  Might not.

Of course.  We might figure it out next week.  Or might never find it.
