    My query, is if there are possible holes in abundance within time as we note in, matter.
    Is this off target thinking ?
    .... Is the present moment the abundance of holes in time ?....
    This makes no sense.

    The sun will not collapse, but in ~5,000,000,000 years (IIRC), it'll become a red giant, then later still it'll blow off it's outer layers leaving a white dwarf behind, which will cool off for another few trillion years. No collapsing involved.

    This is actually not true. At the end of the Sun's lifetime, the radiation pressure that prevents the Sun from collapsing due to its own weight will seize to exist, because there will be no fuel left (hydrogen, helium) to burn. This is at the end of the Red Giant stage. The outer shells will collapse onto the core. The resulting shock wave will then blast off the shell again, while the nucleus remains as a White Dwarf that slowly cools down.

    Oh. Not what most people would think of as a collapse, I guess, but interesting to know.
