## Three Stages of Evolutions of Spacetime/intrinsic Spacetime and Parameters/intrinsic Parameters and the Associated Hierarchies of Spacetimes/intrinsic Spacetimes and Parameters/intrinsic Parameters in a Universe. Part I.

**Authors:** Akindele (Adekugbe) Joseph

Three stages of evolutions of spacetime/intrinsic spacetime and mass/intrinsic mass in
a universe are isolated. The ab initio absolutely immaterial state of a universe with flat
'four-dimensional' absolute-absolute spacetime containing absolute-absolute rest mass
and its underlying flat 'two-dimensional' absolute-absolute intrinsic-intrinsic spacetime
containing absolute-absolute intrinsic-intrinsic rest mass, evolved into an intermediate
absolute material state with flat 'four-dimensional' absolute spacetime containing absolute
rest mass and its underlying flat 'two-dimensional' absolute intrinsic spacetime
containing absolute intrinsic rest mass, at the first stage; followed by evolution into
yet an intermediate relative material state with flat four-dimensional proper spacetime
containing rest mass and its underlying flat two-dimensional proper intrinsic spacetime
containing intrinsic rest mass, at the second stage. These are then followed by evolution
into a final relative material state with flat four-dimensional relativistic spacetime containing
relativistic (or inertial) mass and its underlying flat two-dimensional relativistic
intrinsic spacetime containing relativistic intrinsic mass (or intrinsic inertial mass), at
the third (and final) stage. The three stages commenced and progress simultaneously
and are still on-going in every universe at present. The second and third stages of evolutions
of spacetime/intrinsic spacetime and mass/intrinsic mass in a universe, correspond
to the first and second stages in a gravitational field, already developed in the previous
papers. The associated hierarchies of spacetimes and masses (comprising of three layers
of space-time-mass) in every universe is highlighted.
