Don’t take this the wrong way, but I care about nothing. Meaning I care about the ongoing argument about the meaning of nothing, not that I don’t care about anything. One has to be careful in discussing nothing.
Anyway, I care particularly about the eternally vexing question: “Why is there something rather than nothing.” In other words, why does the universe exist at all?
There is a long and strong philosophical tradition examining these questions. Some trace the argument back to pre-Socratic philosophers. Then there is the great Roman poet and philosopher Lucretius, who made a point in De Rerum Natura (On the Nature of Things) that “nothing can come from nothing.”
