Have you ever wondered where would you find your ancestors if you had the chance to travel back in time? Whether they tried to get rich during the gold rush in California in the 1890s? Or whether they fought in the army of Catherine the Great annexing the Crimea in 1783? Did they perhaps live in Rome when Italian philosopher, astronomer, and mathematician Galileo Galilei arrived there in 1633 to face charges of heresy for advocating Copernican theory, which holds that the Earth revolves around the Sun? Or did they live in South America at the time Magellan discovered the strait down there in the 1520s?
