Even in a city of people too busy for impromptu sidewalk conversations, the sight was too tempting to resist. “They sat down and asked about the big bang and black holes,” Lederman says. “They were good questions. People were very curious.” Soon about 20 people formed a line down the block. They asked Lederman about the strong force, time and space, fusion, and even time travel.
