Darkness Means Ignorance
Ignorance and falsehood are equivalent to darkness. When the lights of knowledge and the rays of verity shine, ignorance as darkness diminishes. This truth has always been throughout the universe and always will be. In the affairs of science, when a new theorem is provided and is in accord with the mindsets, the former theorems (regardless of their apparent strength) are dissolved just like snow that melts in the heat of the hot summer.
