Time Machine Wires — Ancient Sumer Copper Horror

TwoSentenceHorror: "I was relieved when I realized the only damage to the time machine was to the wires."
"All I need to do now is find someone in Ancient Sumer to sell me some good quality copper."

The horror isn’t the damage. The horror is that Ancient Sumer (4500 BCE) was a Bronze Age civilization. They had copper, sure — but not the kind you need for time machine wiring. You’re stuck there forever.
