The chapter describes Professor Gaitonde's strange experience of finding himself in an alternate reality where history had occurred differently. On a train to Bombay, he notices inconsistencies and decides to research at the library, finding accounts that the Marathas won the Battle of Panipat rather than the Mughals. He experiences an even stranger situation of interacting with a public lecture before waking in the hospital, where Rajendra explains his experience was likely due to theories of catastrophe and quantum physics allowing shifts to alternate realities.
