Jennifer was explaining her quantum destabilizer invention to her grandson, Eric.


    “That’s fascinating, Grandma! I proudly tell my friends you won a Nobel Prize!”


    Jennifer blushed shyly. “With it, I solved the greatest paradox of ‘all time’ —pun intended.”

    “What’s that?”


    “Do you remember your grandfather?”


    “Yes,” Eric frowned, “before he passed away.”


    “He wasn’t your grandfather always.”


    “Huh?”


    “You’ll build yourself a time machine—based on my quantum destabilizer.“


    “Oh? Why?”


    “You’ll try testing the grandfather paradox with it someday.”


    “But I would never …”


    “It’s okay. It doesn’t matter. I’ll meet someone else. You underestimated the ‘grandmother paradox.’”
