Tell me about it. I still remember asking my dad what came before the universe when I was a kid and he said, &quot;No, there was no before.&quot; When I inquired again he said &quot;Time is a property of our universe. You can&#x27;t have a before without it. There wasn&#x27;t <i>nothing</i>, there wasn&#x27;t a <i>before</i>. You are part of this universe and cannot exist without it. There&#x27;s no curtain to look behind, this is it.&quot;<p>That realization made me feel pretty stupid and caused a minor existential crisis.
