With powerful telescopes we zoom past the first galaxies, to a time everything was heavily concentrated in the small existing volume. And we keep on going, but without telescopes. In our minds, we try to piece the puzzle together, We reach likely conclusions, such that the universe now springs from an infinitesimal point. Zero.
But let's say we keep peering back in time. We cross the milli, the micro, the nano. Always getting closer, we approach the pico, the femto, the atto. Much nearer that infinitesimal, sizeless instance we move past the zepto and the yocto.
And we keep going, in this fashion. Always getting closer to "zero"...but, maybe, without ever getting there. As if traversing a logarithmic function - time on the x axis; the order of magnitude of volume, if you will, on the y
Can we conclude this first instant ISN'T undefined, like log(0)? That, while we can keep approaching the instant when the universe was infinitesimal...we can never actually reach such a "zero" point?
