The Vanishing Sunlight

Einstein had a teasing analogy about relativity: if a young man sat with a beautiful girl for two hours, it felt like two minutes; if he sat with an old woman, two minutes felt like two hours.

Relativity held that faster-than-light travel could turn back time. Space was static, and only with the dimension of time could everything around them move. Traveling through time and space required finding the critical point between two spacetime continua. An Einstein-Rosen bridge connected a black hole and a white hole formed by immense gravity, creating a spacetime wormhole.

That genius had been thinking about how to achieve time travel; it had nothing to do with the atomic bomb. But making mistakes was human nature, and the smarter a person was, the more severe the consequences they caused. Einstein's mistake this time was far more serious than getting a female classmate pregnant out of wedlock.

If he had been given the chance to regret his original decision and refrain from publishing relativity, would he have done so?

The price would have been that he would no longer be a world-famous physicist. He would have been merely an ordinary teacher at the University of Bern. Like other Jews, he might have been swept into the war, perhaps even hiding in a Frenchman's wine cellar to evade pursuit.

The power of the atomic bomb was unlike that of a warhorse; it had already surpassed humanity's ability to control it. As technology advanced by the day, this sense of losing control made people increasingly anxious. By comparison, the countryside far from the cities was much more relaxing.

Switzerland was not only a paradise for outdoor enthusiasts but also a world-famous health resort. There were many hot spring resorts within Switzerland, the most famous of which was Leukerbad. According
