100,000 feet is equivalent to approximately 0.0000 light-years. This is a very tiny fraction of a light-year.

Light-years measure enormous cosmic distances, while feet measure relatively small terrestrial distances. The difference in scale is so vast that even a large number of feet becomes almost insignificant when compared to a light-year.

The nearest star system to our Sun, Alpha Centauri, is about 4.37 light-years away.

One light-year is an incredibly large number of feet, approximately 3.1 x 10^19 feet. This is why 100,000 feet is such a small fraction of a light-year.
