The Limitations of Technology
With the human eye, we can perceive a vast array of the cosmos. From minute detail of the world around us all the way up through stars and even the dusty appearance of distant galaxies. With that being said, there are limitations to what we can see.
To expand how far we can see, we do this by looking beyond our limits in both directions: big and small.
For the big this is done with, for example, telescopes.
For the small this is done with, for example, microscopes.

This increases our ability to see into the depths of the micro- and macrocosm drastically. We make the mistake, then, of thinking that the improvement in what we can see is so vast that we see to the very limits of reality. In truth, we see to the very limits of our instruments. No different than the limitations of the human eye, technology has this same intrinsic inability to see beyond.
For us, these limits are within the depths of infinity. No matter how deep we look into infinity, there will always be a limit to how far we can see beyond which there is infinitely more, regardless of the lens through which we perceive it. The universe is the manifestation of infinity and no instrumentation can ever pierce its depths.
