The flowers died on Monday. No matter how well-constructed the replacement, the flowers could tell the difference immediately. The weather keep going as normal. The sky looks the same as it always has. The false heat kept the cycles intact. There were plants that survived. Very few, but not none.
The animals were fooled. Although we knew better, our bodies reacted as they always had. We carried on. Our invention left barely a hiccup in the history of the human race. At least, that’s how it seems so far. It’s only been three days since the sun went out, so we still have a ways to go.
