Since many centuries ago, we know the maths of conversion of energy in to force & the reverse. Since about a century we know the maths of conversion of energy into mass & vice versa. We also have the maths of decay of photons into units of spacetime which are constituents of quantum vacuum. Therefore

force, energy, mass, matter, space, time and vacuum are different phases of the same entity and all are quantized. From Einstein's relativity maths,we can know that - 'contraction of 'space' converts 'space' in to time (time dilation) while contraction of 'time' converts 'time' into space.' This indicates that the same entity is changing phase. Since space is expanding, it means that the total potential (magnitude) of time possessed by the universe is decreasing by changing in to space. When the time contained by the universe get's converted fully in to 'space', further expansion of space would 'no more' be possible. Contraction of time means increased velocity of events with simultaneous dilation of space (increase in quantum vacuum), so the universal physical constants do not change. But increase in space (vacuum energy) requires energy, this comes from decay of mass to radiant energy which further deacays to quantum vacuum. The reverse of this process i.e, the process of accretion of mass involves the contraction of space with simultaneous dilation of time. The space between heavenly bodies or particles (with or without mass) which contracts tending to create mass or more mass is the force of gravity.

Contraction of space tends to cause motion and motion tends to cause contraction of space (Force).

The entity 'mass', which provides the energy (or force fields for quantum vacuum) for conversion of time in to space is therefore also the entity 'time'. In this way we see that energy, mass, force, space and time is infact the same entity. The oneness of mass and time is also apparent when they show the same property of dilation with increase in motion.

Motion is therefore conversion of space into time (mass).

Matter is a structure made up of space and time (mass). Acceleration creates mass from space. Resisting the motion of a particle having mass should make it loose mass (energy).Constant motion gives a constant converted amount of space into time (mass). Acceleration goes on creating mass from space (from quantum vacuum force fields/ vacuum energy). All mass produced by acceleration is positive mass. While mass produced by deceleration is negative mass.

The cosmic singularity has a negative mass/energy/time and a negative space/force which equals the positive mass/energy/time and positive space/ force of the universe. Zero mass particle.
