Final answer:
Changes in small scenes are hard to detect due to the limited resolution of the human eye and how distant objects appear smaller. Conversely, larger scenes show detectable changes more easily because they span a greater field of view. The Heisenberg's uncertainty principle has negligible effects on the perception of large objects because Planck's constant is extremely small.
Step-by-step explanation:
The difficulty in noticing a change in a small scene compared to a large one can be explained by several physical principles. When an object is far away, it appears smaller to us, making it difficult to discern small changes. This is due to the limited resolution of the human eye. In contrast, larger scenes or objects can undergo significant changes before we notice because they span a greater field of view and thus motions or changes are more easily detectable.
Considering astronomical observations, as illustrated by the Hubble telescope's view of distant galaxies, the effects of changes in large scenes become more profound. For instance, the light from a cluster of stars that brighten simultaneously will not be seen all at once on Earth. This is because the light from those stars takes different amounts of time to reach us, spreading the perceived change over a longer timeframe.
Moreover, the Heisenberg's uncertainty principle is not generally noticeable in everyday life because Planck's constant is extremely small. This means that for large objects, the uncertainty in measuring position and momentum is so minute that it does not affect our daily observations.
